used to rendering or shading but only as an underlying volume distance to - determine dynamic step size, by carefully selecting an equation (polynomial for speed) to - step as a function of overall density (not necessarialy rendered) the visual results can be - the same as a naive implementation with ~40% increase in rendering performance. - - Since the dynamic marching step size is even less uniform due to steps not being rendered at all - the fog is evaluated as the difference of the fog integral at each rendered step. - -*/ - -mat2 rot(in float a){float c = cos(a), s = sin(a);return

See suggested mappings in imgui.h ImGuiNavInput_ + download PNG/PSD at http://goo.gl/9LgVZW - - - PROGRAMMER GUIDE - ================ - - READ FIRST - ---------- - - Remember to read the FAQ (https://www.dearimgui.org/faq) - - Your code creates the UI, if your code doesn't run the UI is gone! The UI can be highly dynamic, there are no construction - or destruction steps, less superfluous data retention on your side, less state duplication, less state synchronization, less bugs. - - Call and read ImGui::ShowDemoWindow() for demo code demonstrating most features. - - The library is designed to be built from sources. Avoid pre-compiled binaries and packaged versions. See imconfig.h to configure your build. - - Dear ImGui is an implementation of the IMGUI paradigm (immediate-mode graphical user interface, a term coined by Casey Muratori). - You can learn about IMGUI principles at http://www.johno.se/book/imgui.html, http://mollyrocket.com/861 & more links docs/README.md. - - Dear ImGui is a "single pass" rasterizing implementation of the IMGUI paradigm, aimed at ease of use and high-performances. - For every application frame your UI code will be called only once. This is in contrast to e.g. Unity's own implementation of an IMGUI, - where the UI code is called multiple times ("multiple passes") from a single entry point. There are pros and cons to both approaches. - - Our origin are on the top-left. In axis aligned bounding boxes, Min = top-left, Max = bottom-right. - - This codebase is also optimized to yield decent performances with typical "Debug" builds settings. - - Please make sure you have asserts enabled (IM_ASSERT redirects to assert() by default, but can be redirected). - If you get an assert, read the messages and comments around the assert. - - C++: this is a very C-ish codebase: we don't rely on C++11, we don't include any C++ headers, and ImGui:: is a namespace. - - C++: ImVec2/ImVec4 do not expose math operators by default, because it is expected that you use your own math types. - See FAQ "How can I use my own math types instead of ImVec2/ImVec4?" for details about setting up imconfig.h for that. - However, imgui_internal.h can optionally export math operators for ImVec2/ImVec4, which we use in this codebase. - - C++: pay attention that ImVector<> manipulates plain-old-data and does not honor construction/destruction (avoid using it in your code!). - - HOW TO UPDATE TO A NEWER VERSION OF DEAR IMGUI - ---------------------------------------------- - - Overwrite all the sources files except for imconfig.h (if you have made modification to your copy of imconfig.h) - - Or maintain your own branch where you have imconfig.h modified. - - Read the "API BREAKING CHANGES" section (below). This is where we list occasional API breaking changes. - If a function/type has been renamed / or marked obsolete, try to fix the name in your code before it is permanently removed - from the public API. If you have a problem with a missing function/symbols, search for its name in the code, there will - likely be a comment about it. Please report any issue to the GitHub page! - - Try to keep your copy of dear imgui reasonably up to date. - - GETTING STARTED WITH INTEGRATING DEAR IMGUI IN YOUR CODE/ENGINE - --------------------------------------------------------------- - - Run and study the examples and demo in imgui_demo.cpp to get acquainted with the library. - - In the majority of cases you should be able to use unmodified back-ends files available in the examples/ folder. - - Add the Dear ImGui source files to your projects or using your preferred build system. - It is recommended you build and statically link the .cpp files as part of your project and NOT as shared library (DLL). - - You can later customize the imconfig.h file to tweak some compile-time behavior, such as integrating Dear ImGui types with your own maths types. - - When using Dear ImGui, your programming IDE is your friend: follow the declaration of variables, functions and types to find comments about them. - - Dear ImGui never touches or knows about your GPU state. The only function that knows about GPU is the draw function that you provide. - Effectively it means you can create widgets at any time in your code, regardless of considerations of being in "update" vs "render" - phases of your own application. All rendering information are stored into command-lists that you will retrieve after calling ImGui::Render(). - - Refer to the bindings and demo applications in the examples/ folder for instruction on how to setup your code. - - If you are running over a standard OS with a common graphics API, you should be able to use unmodified imgui_impl_*** files from the examples/ folder. - - HOW A SIMPLE APPLICATION MAY LOOK LIKE - -------------------------------------- - EXHIBIT 1: USING THE EXAMPLE BINDINGS (imgui_impl_XXX.cpp files from the examples/ folder). - - // Application init: create a dear imgui context, setup some options, load fonts - ImGui::CreateContext(); - ImGuiIO& io = ImGui::GetIO(); - // TODO: Set optional io.ConfigFlags values, e.g. 'io.ConfigFlags |= ImGuiConfigFlags_NavEnableKeyboard' to enable keyboard controls. - // TODO: Fill optional fields of the io structure later. - // TODO: Load TTF/OTF fonts if you don't want to use the default font. - - // Initialize helper Platform and Renderer bindings (here we are using imgui_impl_win32.cpp and imgui_impl_dx11.cpp) - ImGui_ImplWin32_Init(hwnd); - ImGui_ImplDX11_Init(g_pd3dDevice, g_pd3dDeviceContext); - - // Application main loop - while (true) - { - // Feed inputs to dear imgui, start new frame - ImGui_ImplDX11_NewFrame(); - ImGui_ImplWin32_NewFrame(); - ImGui::NewFrame(); - - // Any application code here - ImGui::Text("Hello, world!"); - - // Render dear imgui into screen - ImGui::Render(); - ImGui_ImplDX11_RenderDrawData(ImGui::GetDrawData()); - g_pSwapChain->Present(1, 0); - } - - // Shutdown - ImGui_ImplDX11_Shutdown(); - ImGui_ImplWin32_Shutdown(); - ImGui::DestroyContext(); - - EXHIBIT 2: IMPLEMENTING CUSTOM BINDING / CUSTOM ENGINE - - // Application init: create a dear imgui context, setup some options, load fonts - ImGui::CreateContext(); - ImGuiIO& io = ImGui::GetIO(); - // TODO: Set optional io.ConfigFlags values, e.g. 'io.ConfigFlags |= ImGuiConfigFlags_NavEnableKeyboard' to enable keyboard controls. - // TODO: Fill optional fields of the io structure later. - // TODO: Load TTF/OTF fonts if you don't want to use the default font. - - // Build and load the texture atlas into a texture - // (In the examples/ app this is usually done within the ImGui_ImplXXX_Init() function from one of the demo Renderer) - int width, height; - unsigned char* pixels = NULL; - io.Fonts->GetTexDataAsRGBA32(&pixels, &width, &height); - - // At this point you've got the texture data and you need to upload that your your graphic system: - // After we have created the texture, store its pointer/identifier (_in whichever format your engine uses_) in 'io.Fonts->TexID'. - // This will be passed back to your via the renderer.

In every cases you need to pass on the inputs to Dear ImGui. - - Refer to the FAQ for more information. Amusingly, it is called a FAQ because people frequently run into the same issues! - - USING GAMEPAD/KEYBOARD NAVIGATION CONTROLS - ------------------------------------------ - - The gamepad/keyboard navigation is fairly functional and keeps being improved. - - Gamepad support is particularly useful to use Dear ImGui on a console system (e.g. PS4, Switch, XB1) without a mouse! - - You can ask questions and report issues at https://github.com/ocornut/imgui/issues/787 - - The initial focus was to support game controllers, but keyboard is becoming increasingly and decently usable. - - Keyboard: - - Set io.ConfigFlags |= ImGuiConfigFlags_NavEnableKeyboard to enable. - NewFrame() will automatically fill io.NavInputs[] based on your io.KeysDown[] + io.KeyMap[] arrays. - - When keyboard navigation is active (io.NavActive + ImGuiConfigFlags_NavEnableKeyboard), the io.WantCaptureKeyboard flag - will be set. For more advanced uses, you may want to read from: - - io.NavActive: true when a window is focused and it doesn't have the ImGuiWindowFlags_NoNavInputs flag set. - - io.NavVisible: true when the navigation cursor is visible (and usually goes false when mouse is used). - - or query focus information with e.g. IsWindowFocused(ImGuiFocusedFlags_AnyWindow), IsItemFocused() etc. functions. - Please reach out if you think the game vs navigation input sharing could be improved. - - Gamepad: - - Set io.ConfigFlags |= ImGuiConfigFlags_NavEnableGamepad to enable. - - Backend: Set io.BackendFlags |= ImGuiBackendFlags_HasGamepad + fill the io.NavInputs[] fields before calling NewFrame(). - Note that io.NavInputs[] is cleared by EndFrame(). - - See 'enum ImGuiNavInput_' in imgui.h for a description of inputs. For each entry of io.NavInputs[], set the following values: - 0.0f= not held. 1.0f= fully held. Pass intermediate 0.0f..1.0f values for analog triggers/sticks. - - We uses a simple >0.0f test for activation testing, and won't attempt to test for a dead-zone. - Your code will probably need to transform your raw inputs (such as e.g. remapping your 0.2..0.9 raw input range to 0.0..1.0 imgui range, etc.). - - You can download PNG/PSD files depicting the gamepad controls for common controllers at: http://goo.gl/9LgVZW. - - If you need to share inputs between your game and the imgui parts, the easiest approach is to go all-or-nothing, with a buttons combo - to toggle the target. Please reach out if you think the game vs navigation input sharing could be improved. - - Mouse: - - PS4 users: Consider emulating a mouse cursor with DualShock4 touch pad or a spare analog stick as a mouse-emulation fallback. - - Consoles/Tablet/Phone users: Consider using a Synergy 1.x server (on your PC) + uSynergy.c (on your console/tablet/phone app) to share your PC mouse/keyboard. - - On a TV/console system where readability may be lower or mouse inputs may be awkward, you may want to set the ImGuiConfigFlags_NavEnableSetMousePos flag. - Enabling ImGuiConfigFlags_NavEnableSetMousePos + ImGuiBackendFlags_HasSetMousePos instructs dear imgui to move your mouse cursor along with navigation movements. - When enabled, the NewFrame() function may alter 'io.MousePos' and set 'io.WantSetMousePos' to notify you that it wants the mouse cursor to be moved. - When that happens your back-end NEEDS to move the OS or underlying mouse cursor on the next frame. Some of the binding in examples/ do that. - (If you set the NavEnableSetMousePos flag but don't honor 'io.WantSetMousePos' properly, imgui will misbehave as it will see your mouse as moving back and forth!) - (In a setup when you may not have easy control over the mouse cursor, e.g. uSynergy.c doesn't expose moving remote mouse cursor, you may want - to set a boolean to ignore your other external mouse positions until the external source is moved again.) - - - API BREAKING CHANGES - ==================== - - Occasionally introducing changes that are breaking the API. We try to make the breakage minor and easy to fix. - Below is a change-log of API breaking changes only. If you are using one of the functions listed, expect to have to fix some code. - When you are not sure about a old symbol or function name, try using the Search/Find function of your IDE to look for comments or references in all imgui files. - You can read releases logs https://github.com/ocornut/imgui/releases for more details. - - (Docking/Viewport Branch) - - 2019/XX/XX (1.XX) - when multi-viewports are enabled, all positions will be in your natural OS coordinates space. It means that: - - reference to hard-coded positions such as in SetNextWindowPos(ImVec2(0,0)) are probably not what you want anymore. - you may use GetMainViewport()->Pos to offset hard-coded positions, e.g. SetNextWindowPos(GetMainViewport()->Pos) - - likewise io.MousePos and GetMousePos() will use OS coordinates. - If you query mouse positions to interact with non-imgui coordinates you will need to offset them, e.g. subtract GetWindowViewport()->Pos. - - 2019/XX/XX (1.XX) - Moved IME support functions from io.ImeSetInputScreenPosFn, io.ImeWindowHandle to the PlatformIO api. - - - - 2020/01/22 (1.75) - ImDrawList::AddCircle()/AddCircleFilled() functions don't accept negative radius any more. - - 2019/12/17 (1.75) - made Columns() limited to 64 columns by asserting above that limit. While the current code technically supports it, future code may not so we're putting the restriction ahead. - - 2019/12/13 (1.75) - [imgui_internal.h] changed ImRect() default constructor initializes all fields to 0.0f instead of (FLT_MAX,FLT_MAX,-FLT_MAX,-FLT_MAX). If you used ImRect::Add() to create bounding boxes by adding multiple points into it, you may need to fix your initial value. - - 2019/12/08 (1.75) - removed redirecting functions/enums that were marked obsolete in 1.53 (December 2017): - - ShowTestWindow() -> use ShowDemoWindow() - - IsRootWindowFocused() -> use IsWindowFocused(ImGuiFocusedFlags_RootWindow) - - IsRootWindowOrAnyChildFocused() -> use IsWindowFocused(ImGuiFocusedFlags_RootAndChildWindows) - - SetNextWindowContentWidth(w) -> use SetNextWindowContentSize(ImVec2(w, 0.0f) - - GetItemsLineHeightWithSpacing() -> use GetFrameHeightWithSpacing() - - ImGuiCol_ChildWindowBg -> use ImGuiCol_ChildBg - - ImGuiStyleVar_ChildWindowRounding -> use ImGuiStyleVar_ChildRounding - - ImGuiTreeNodeFlags_AllowOverlapMode -> use ImGuiTreeNodeFlags_AllowItemOverlap - - IMGUI_DISABLE_TEST_WINDOWS -> use IMGUI_DISABLE_DEMO_WINDOWS - - 2019/12/08 (1.75) - obsoleted calling ImDrawList::PrimReserve() with a negative count (which was the vaguely documented and rarely if ever used). Instead we added an explicit PrimUnreserve() API. - - 2019/12/06 (1.75) - removed implicit default parameter to IsMouseDragging(int button = 0) to be consistent with other mouse functions (none of the other functions have it). - - 2019/11/21 (1.74) - ImFontAtlas::AddCustomRectRegular() now requires an ID larger than 0x110000 (instead of 0x10000) to conform with supporting Unicode planes 1-16 in a future update. ID below 0x110000 will now assert. - - 2019/11/19 (1.74) - renamed IMGUI_DISABLE_FORMAT_STRING_FUNCTIONS to IMGUI_DISABLE_DEFAULT_FORMAT_FUNCTIONS for consistency. - - 2019/11/19 (1.74) - renamed IMGUI_DISABLE_MATH_FUNCTIONS to IMGUI_DISABLE_DEFAULT_MATH_FUNCTIONS for consistency. - - 2019/10/22 (1.74) - removed redirecting functions/enums that were marked obsolete in 1.52 (October 2017): - - Begin() [old 5 args version] -> use Begin() [3 args], use SetNextWindowSize() SetNextWindowBgAlpha() if needed - - IsRootWindowOrAnyChildHovered() -> use IsWindowHovered(ImGuiHoveredFlags_RootAndChildWindows) - - AlignFirstTextHeightToWidgets() -> use AlignTextToFramePadding() - - SetNextWindowPosCenter() -> use SetNextWindowPos() with a pivot of (0.5f, 0.5f) - - ImFont::Glyph -> use ImFontGlyph - - 2019/10/14 (1.74) - inputs: Fixed a miscalculation in the keyboard/mouse "typematic" repeat delay/rate calculation, used by keys and e.g. repeating mouse buttons as well as the GetKeyPressedAmount() function. - if you were using a non-default value for io.KeyRepeatRate (previous default was 0.250), you can add +io.KeyRepeatDelay to it to compensate for the fix. - The function was triggering on: 0.0 and (delay+rate*N) where (N>=1). Fixed formula responds to (N>=0). Effectively it made io.KeyRepeatRate behave like it was set to (io.KeyRepeatRate + io.KeyRepeatDelay). - If you never altered io.KeyRepeatRate nor used GetKeyPressedAmount() this won't affect you. - - 2019/07/15 (1.72) - removed TreeAdvanceToLabelPos() which is rarely used and only does SetCursorPosX(GetCursorPosX() + GetTreeNodeToLabelSpacing()). Kept redirection function (will obsolete). - - 2019/07/12 (1.72) - renamed ImFontAtlas::CustomRect to ImFontAtlasCustomRect. Kept redirection typedef (will obsolete). - - 2019/06/14 (1.72) - removed redirecting functions/enums names that were marked obsolete in 1.51 (June 2017): ImGuiCol_Column*, ImGuiSetCond_*, IsItemHoveredRect(), IsPosHoveringAnyWindow(), IsMouseHoveringAnyWindow(), IsMouseHoveringWindow(), IMGUI_ONCE_UPON_A_FRAME. Grep this log for details and new names, or see how they were implemented until 1.71. - - 2019/06/07 (1.71) - rendering of child window outer decorations (bg color, border, scrollbars) is now performed as part of the parent window. If you have - overlapping child windows in a same parent, and relied on their relative z-order to be mapped to their submission order, this will affect your rendering. - This optimization is disabled if the parent window has no visual output, because it appears to be the most common situation leading to the creation of overlapping child windows. - Please reach out if you are affected. - - 2019/05/13 (1.71) - renamed SetNextTreeNodeOpen() to SetNextItemOpen(). Kept inline redirection function (will obsolete). - - 2019/05/11 (1.71) - changed io.AddInputCharacter(unsigned short c) signature to io.AddInputCharacter(unsigned int c). - - 2019/04/29 (1.70) - improved ImDrawList thick strokes (>1.0f) preserving correct thickness up to 90 degrees angles (e.g. rectangles). If you have custom rendering using thick lines, they will appear thicker now. - - 2019/04/29 (1.70) - removed GetContentRegionAvailWidth(), use GetContentRegionAvail().x instead. Kept inline redirection function (will obsolete). - - 2019/03/04 (1.69) - renamed GetOverlayDrawList() to GetForegroundDrawList(). Kept redirection function (will obsolete). - - 2019/02/26 (1.69) - renamed ImGuiColorEditFlags_RGB/ImGuiColorEditFlags_HSV/ImGuiColorEditFlags_HEX to ImGuiColorEditFlags_DisplayRGB/ImGuiColorEditFlags_DisplayHSV/ImGuiColorEditFlags_DisplayHex. Kept redirection enums (will obsolete). - - 2019/02/14 (1.68) - made it illegal/assert when io.DisplayTime == 0.0f (with an exception for the first frame). If for some reason your time step calculation gives you a zero value, replace it with a dummy small value! - - 2019/02/01 (1.68) - removed io.DisplayVisibleMin/DisplayVisibleMax (which were marked obsolete and removed from viewport/docking branch already). - - 2019/01/06 (1.67) - renamed io.InputCharacters[], marked internal as was always intended. Please don't access directly, and use AddInputCharacter() instead! - - 2019/01/06 (1.67) - renamed ImFontAtlas::GlyphRangesBuilder to ImFontGlyphRangesBuilder. Kept redirection typedef (will obsolete). - - 2018/12/20 (1.67) - made it illegal to call Begin("") with an empty string. This somehow half-worked before but had various undesirable side-effects. - - 2018/12/10 (1.67) - renamed io.ConfigResizeWindowsFromEdges to io.ConfigWindowsResizeFromEdges as we are doing a large pass on configuration flags. - - 2018/10/12 (1.66) - renamed misc/stl/imgui_stl.* to misc/cpp/imgui_stdlib.* in prevision for other C++ helper files. - - 2018/09/28 (1.66) - renamed SetScrollHere() to SetScrollHereY(). Kept redirection function (will obsolete). - - 2018/09/06 (1.65) - renamed stb_truetype.h to imstb_truetype.h, stb_textedit.h to imstb_textedit.h, and stb_rect_pack.h to imstb_rectpack.h. - If you were conveniently using the imgui copy of those STB headers in your project you will have to update your include paths. - - 2018/09/05 (1.65) - renamed io.OptCursorBlink/io.ConfigCursorBlink to io.ConfigInputTextCursorBlink. (#1427) - - 2018/08/31 (1.64) - added imgui_widgets.cpp file, extracted and moved widgets code out of imgui.cpp into imgui_widgets.cpp. Re-ordered some of the code remaining in imgui.cpp. - NONE OF THE FUNCTIONS HAVE CHANGED. THE CODE IS SEMANTICALLY 100% IDENTICAL, BUT _EVERY_ FUNCTION HAS BEEN MOVED. - Because of this, any local modifications to imgui.cpp will likely conflict when you update. Read docs/CHANGELOG.txt for suggestions. - - 2018/08/22 (1.63) - renamed IsItemDeactivatedAfterChange() to IsItemDeactivatedAfterEdit() for consistency with new IsItemEdited() API. Kept redirection function (will obsolete soonish as IsItemDeactivatedAfterChange() is very recent). - - 2018/08/21 (1.63) - renamed ImGuiTextEditCallback to ImGuiInputTextCallback, ImGuiTextEditCallbackData to ImGuiInputTextCallbackData for consistency. Kept redirection types (will obsolete). - - 2018/08/21 (1.63) - removed ImGuiInputTextCallbackData::ReadOnly since it is a duplication of (ImGuiInputTextCallbackData::Flags & ImGuiInputTextFlags_ReadOnly). - - 2018/08/01 (1.63) - removed per-window ImGuiWindowFlags_ResizeFromAnySide beta flag in favor of a global io.ConfigResizeWindowsFromEdges [update 1.67 renamed to ConfigWindowsResizeFromEdges] to enable the feature. - - 2018/08/01 (1.63) - renamed io.OptCursorBlink to io.ConfigCursorBlink [-> io.ConfigInputTextCursorBlink in 1.65], io.OptMacOSXBehaviors to ConfigMacOSXBehaviors for consistency. - - 2018/07/22 (1.63) - changed ImGui::GetTime() return value from float to double to avoid accumulating floating point imprecisions over time. - - 2018/07/08 (1.63) - style: renamed ImGuiCol_ModalWindowDarkening to ImGuiCol_ModalWindowDimBg for consistency with other features. Kept redirection enum (will obsolete). - - 2018/06/08 (1.62) - examples: the imgui_impl_xxx files have been split to separate platform (Win32, Glfw, SDL2, etc.) from renderer (DX11, OpenGL, Vulkan, etc.). - old bindings will still work as is, however prefer using the separated bindings as they will be updated to support multi-viewports. - when adopting new bindings follow the main.cpp code of your preferred examples/ folder to know which functions to call. - in particular, note that old bindings called ImGui::NewFrame() at the end of their ImGui_ImplXXXX_NewFrame() function. - - 2018/06/06 (1.62) - renamed GetGlyphRangesChinese() to GetGlyphRangesChineseFull() to distinguish other variants and discourage using the full set. - - 2018/06/06 (1.62) - TreeNodeEx()/TreeNodeBehavior(): the ImGuiTreeNodeFlags_CollapsingHeader helper now include the ImGuiTreeNodeFlags_NoTreePushOnOpen flag. See Changelog for details. - - 2018/05/03 (1.61) - DragInt(): the default compile-time format string has been changed from "%.0f" to "%d", as we are not using integers internally any more. - If you used DragInt() with custom format strings, make sure you change them to use %d or an integer-compatible format. - To honor backward-compatibility, the DragInt() code will currently parse and modify format strings to replace %*f with %d, giving time to users to upgrade their code. - If you have IMGUI_DISABLE_OBSOLETE_FUNCTIONS enabled, the code will instead assert! You may run a reg-exp search on your codebase for e.g. "DragInt.*%f" to help you find them. - - 2018/04/28 (1.61) - obsoleted InputFloat() functions taking an optional "int decimal_precision" in favor of an equivalent and more flexible "const char* format", - consistent with other functions. Kept redirection functions (will obsolete). - - 2018/04/09 (1.61) - IM_DELETE() helper function added in 1.60 doesn't clear the input _pointer_ reference, more consistent with expectation and allows passing r-value. - - 2018/03/20 (1.60) - renamed io.WantMoveMouse to io.WantSetMousePos for consistency and ease of understanding (was added in 1.52, _not_ used by core and only honored by some binding ahead of merging the Nav branch). - - 2018/03/12 (1.60) - removed ImGuiCol_CloseButton, ImGuiCol_CloseButtonActive, ImGuiCol_CloseButtonHovered as the closing cross uses regular button colors now. - - 2018/03/08 (1.60) - changed ImFont::DisplayOffset.y to default to 0 instead of +1. Fixed rounding of Ascent/Descent to match TrueType renderer. If you were adding or subtracting to ImFont::DisplayOffset check if your fonts are correctly aligned vertically. - - 2018/03/03 (1.60) - renamed ImGuiStyleVar_Count_ to ImGuiStyleVar_COUNT and ImGuiMouseCursor_Count_ to ImGuiMouseCursor_COUNT for consistency with other public enums. - - 2018/02/18 (1.60) - BeginDragDropSource(): temporarily removed the optional mouse_button=0 parameter because it is not really usable in many situations at the moment. - - 2018/02/16 (1.60) - obsoleted the io.RenderDrawListsFn callback, you can call your graphics engine render function after ImGui::Render(). Use ImGui::GetDrawData() to retrieve the ImDrawData* to display. - - 2018/02/07 (1.60) - reorganized context handling to be more explicit, - - YOU NOW NEED TO CALL ImGui::CreateContext() AT THE BEGINNING OF YOUR APP, AND CALL ImGui::DestroyContext() AT THE END. - - removed Shutdown() function, as DestroyContext() serve this purpose. - - you may pass a ImFontAtlas* pointer to CreateContext() to share a font atlas between contexts. Otherwise CreateContext() will create its own font atlas instance. - - removed allocator parameters from CreateContext(), they are now setup with SetAllocatorFunctions(), and shared by all contexts. - - removed the default global context and font atlas instance, which were confusing for users of DLL reloading and users of multiple contexts. - - 2018/01/31 (1.60) - moved sample TTF files from extra_fonts/ to misc/fonts/. If you loaded files directly from the imgui repo you may need to update your paths. - - 2018/01/11 (1.60) - obsoleted IsAnyWindowHovered() in favor of IsWindowHovered(ImGuiHoveredFlags_AnyWindow). Kept redirection function (will obsolete). - - 2018/01/11 (1.60) - obsoleted IsAnyWindowFocused() in favor of IsWindowFocused(ImGuiFocusedFlags_AnyWindow). Kept redirection function (will obsolete). - - 2018/01/03 (1.60) - renamed ImGuiSizeConstraintCallback to ImGuiSizeCallback, ImGuiSizeConstraintCallbackData to ImGuiSizeCallbackData. - - 2017/12/29 (1.60) - removed CalcItemRectClosestPoint() which was weird and not really used by anyone except demo code. If you need it it's easy to replicate on your side. - - 2017/12/24 (1.53) - renamed the emblematic ShowTestWindow() function to ShowDemoWindow(). Kept redirection function (will obsolete). - - 2017/12/21 (1.53) - ImDrawList: renamed style.AntiAliasedShapes to style.AntiAliasedFill for consistency and as a way to explicitly break code that manipulate those flag at runtime. You can now manipulate ImDrawList::Flags - - 2017/12/21 (1.53) - ImDrawList: removed 'bool anti_aliased = true' final parameter of ImDrawList::AddPolyline() and ImDrawList::AddConvexPolyFilled(). Prefer manipulating ImDrawList::Flags if you need to toggle them during the frame. - - 2017/12/14 (1.53) - using the ImGuiWindowFlags_NoScrollWithMouse flag on a child window forwards the mouse wheel event to the parent window, unless either ImGuiWindowFlags_NoInputs or ImGuiWindowFlags_NoScrollbar are also set. - - 2017/12/13 (1.53) - renamed GetItemsLineHeightWithSpacing() to GetFrameHeightWithSpacing(). Kept redirection function (will obsolete). - - 2017/12/13 (1.53) - obsoleted IsRootWindowFocused() in favor of using IsWindowFocused(ImGuiFocusedFlags_RootWindow). Kept redirection function (will obsolete). - - obsoleted IsRootWindowOrAnyChildFocused() in favor of using IsWindowFocused(ImGuiFocusedFlags_RootAndChildWindows). Kept redirection function (will obsolete). - - 2017/12/12 (1.53) - renamed ImGuiTreeNodeFlags_AllowOverlapMode to ImGuiTreeNodeFlags_AllowItemOverlap. Kept redirection enum (will obsolete). - - 2017/12/10 (1.53) - removed SetNextWindowContentWidth(), prefer using SetNextWindowContentSize(). Kept redirection function (will obsolete). - - 2017/11/27 (1.53) - renamed ImGuiTextBuffer::append() helper to appendf(), appendv() to appendfv(). If you copied the 'Log' demo in your code, it uses appendv() so that needs to be renamed. - - 2017/11/18 (1.53) - Style, Begin: removed ImGuiWindowFlags_ShowBorders window flag. Borders are now fully set up in the ImGuiStyle structure (see e.g. style.FrameBorderSize, style.WindowBorderSize). Use ImGui::ShowStyleEditor() to look them up. - Please note that the style system will keep evolving (hopefully stabilizing in Q1 2018), and so custom styles will probably subtly break over time. It is recommended you use the StyleColorsClassic(), StyleColorsDark(), StyleColorsLight() functions. - - 2017/11/18 (1.53) - Style: removed ImGuiCol_ComboBg in favor of combo boxes using ImGuiCol_PopupBg for consistency. - - 2017/11/18 (1.53) - Style: renamed ImGuiCol_ChildWindowBg to ImGuiCol_ChildBg. - - 2017/11/18 (1.53) - Style: renamed style.ChildWindowRounding to style.ChildRounding, ImGuiStyleVar_ChildWindowRounding to ImGuiStyleVar_ChildRounding. - - 2017/11/02 (1.53) - obsoleted IsRootWindowOrAnyChildHovered() in favor of using IsWindowHovered(ImGuiHoveredFlags_RootAndChildWindows); - - 2017/10/24 (1.52) - renamed IMGUI_DISABLE_WIN32_DEFAULT_CLIPBOARD_FUNCS/IMGUI_DISABLE_WIN32_DEFAULT_IME_FUNCS to IMGUI_DISABLE_WIN32_DEFAULT_CLIPBOARD_FUNCTIONS/IMGUI_DISABLE_WIN32_DEFAULT_IME_FUNCTIONS for consistency. - - 2017/10/20 (1.52) - changed IsWindowHovered() default parameters behavior to return false if an item is active in another window (e.g. click-dragging item from another window to this window). You can use the newly introduced IsWindowHovered() flags to requests this specific behavior if you need it. - - 2017/10/20 (1.52) - marked IsItemHoveredRect()/IsMouseHoveringWindow() as obsolete, in favor of using the newly introduced flags for IsItemHovered() and IsWindowHovered(). See https://github.com/ocornut/imgui/issues/1382 for details. - removed the IsItemRectHovered()/IsWindowRectHovered() names introduced in 1.51 since they were merely more consistent names for the two functions we are now obsoleting. - IsItemHoveredRect() --> IsItemHovered(ImGuiHoveredFlags_RectOnly) - IsMouseHoveringAnyWindow() --> IsWindowHovered(ImGuiHoveredFlags_AnyWindow) - IsMouseHoveringWindow() --> IsWindowHovered(ImGuiHoveredFlags_AllowWhenBlockedByPopup | ImGuiHoveredFlags_AllowWhenBlockedByActiveItem) [weird, old behavior] - - 2017/10/17 (1.52) - marked the old 5-parameters version of Begin() as obsolete (still available). Use SetNextWindowSize()+Begin() instead! - - 2017/10/11 (1.52) - renamed AlignFirstTextHeightToWidgets() to AlignTextToFramePadding(). Kept inline redirection function (will obsolete). - - 2017/09/26 (1.52) - renamed ImFont::Glyph to ImFontGlyph. Kept redirection typedef (will obsolete). - - 2017/09/25 (1.52) - removed SetNextWindowPosCenter() because SetNextWindowPos() now has the optional pivot information to do the same and more. Kept redirection function (will obsolete). - - 2017/08/25 (1.52) - io.MousePos needs to be set to ImVec2(-FLT_MAX,-FLT_MAX) when mouse is unavailable/missing. Previously ImVec2(-1,-1) was enough but we now accept negative mouse coordinates. In your binding if you need to support unavailable mouse, make sure to replace "io.MousePos = ImVec2(-1,-1)" with "io.MousePos = ImVec2(-FLT_MAX,-FLT_MAX)". - - 2017/08/22 (1.51) - renamed IsItemHoveredRect() to IsItemRectHovered(). Kept inline redirection function (will obsolete). -> (1.52) use IsItemHovered(ImGuiHoveredFlags_RectOnly)! - - renamed IsMouseHoveringAnyWindow() to IsAnyWindowHovered() for consistency. Kept inline redirection function (will obsolete). - - renamed IsMouseHoveringWindow() to IsWindowRectHovered() for consistency. Kept inline redirection function (will obsolete). - - 2017/08/20 (1.51) - renamed GetStyleColName() to GetStyleColorName() for consistency. - - 2017/08/20 (1.51) - added PushStyleColor(ImGuiCol idx, ImU32 col) overload, which _might_ cause an "ambiguous call" compilation error if you are using ImColor() with implicit cast. Cast to ImU32 or ImVec4 explicily to fix. - - 2017/08/15 (1.51) - marked the weird IMGUI_ONCE_UPON_A_FRAME helper macro as obsolete. prefer using the more explicit ImGuiOnceUponAFrame type. - - 2017/08/15 (1.51) - changed parameter order for BeginPopupContextWindow() from (const char*,int buttons,bool also_over_items) to (const char*,int buttons,bool also_over_items). Note that most calls relied on default parameters completely. - - 2017/08/13 (1.51) - renamed ImGuiCol_Column to ImGuiCol_Separator, ImGuiCol_ColumnHovered to ImGuiCol_SeparatorHovered, ImGuiCol_ColumnActive to ImGuiCol_SeparatorActive. Kept redirection enums (will obsolete). - - 2017/08/11 (1.51) - renamed ImGuiSetCond_Always to ImGuiCond_Always, ImGuiSetCond_Once to ImGuiCond_Once, ImGuiSetCond_FirstUseEver to ImGuiCond_FirstUseEver, ImGuiSetCond_Appearing to ImGuiCond_Appearing. Kept redirection enums (will obsolete). - - 2017/08/09 (1.51) - removed ValueColor() helpers, they are equivalent to calling Text(label) + SameLine() + ColorButton(). - - 2017/08/08 (1.51) - removed ColorEditMode() and ImGuiColorEditMode in favor of ImGuiColorEditFlags and parameters to the various Color*() functions. The SetColorEditOptions() allows to initialize default but the user can still change them with right-click context menu. - - changed prototype of 'ColorEdit4(const char* label, float col[4], bool show_alpha = true)' to 'ColorEdit4(const char* label, float col[4], ImGuiColorEditFlags flags = 0)', where passing flags = 0x01 is a safe no-op (hello dodgy backward compatibility!). - check and run the demo window, under "Color/Picker Widgets", to understand the various new options. - - changed prototype of rarely used 'ColorButton(ImVec4 col, bool small_height = false, bool outline_border = true)' to 'ColorButton(const char* desc_id, ImVec4 col, ImGuiColorEditFlags flags = 0, ImVec2 size = ImVec2(0,0))' - - 2017/07/20 (1.51) - removed IsPosHoveringAnyWindow(ImVec2), which was partly broken and misleading. ASSERT + redirect user to io.WantCaptureMouse - - 2017/05/26 (1.50) - removed ImFontConfig::MergeGlyphCenterV in favor of a more multipurpose ImFontConfig::GlyphOffset. - - 2017/05/01 (1.50) - renamed ImDrawList::PathFill() (rarely used directly) to ImDrawList::PathFillConvex() for clarity. - - 2016/11/06 (1.50) - BeginChild(const char*) now applies the stack id to the provided label, consistently with other functions as it should always have been. It shouldn't affect you unless (extremely unlikely) you were appending multiple times to a same child from different locations of the stack id. If that's the case, generate an id with GetId() and use it instead of passing string to BeginChild(). - - 2016/10/15 (1.50) - avoid 'void* user_data' parameter to io.SetClipboardTextFn/io.GetClipboardTextFn pointers. We pass io.ClipboardUserData to it. - - 2016/09/25 (1.50) - style.WindowTitleAlign is now a ImVec2 (ImGuiAlign enum was removed). set to (0.5f,0.5f) for horizontal+vertical centering, (0.0f,0.0f) for upper-left, etc. - - 2016/07/30 (1.50) - SameLine(x) with x>0.0f is now relative to left of column/group if any, and not always to left of window. This was sort of always the intent and hopefully breakage should be minimal. - - 2016/05/12 (1.49) - title bar (using ImGuiCol_TitleBg/ImGuiCol_TitleBgActive colors) isn't rendered over a window background (ImGuiCol_WindowBg color) anymore. - If your TitleBg/TitleBgActive alpha was 1.0f or you are using the default theme it will not affect you, otherwise if <1.0f you need tweak your custom theme to readjust for the fact that we don't draw a WindowBg background behind the title bar. - This helper function will convert an old TitleBg/TitleBgActive color into a new one with the same visual output, given the OLD color and the OLD WindowBg color: - ImVec4 ConvertTitleBgCol(const ImVec4& win_bg_col, const ImVec4& title_bg_col) { float new_a = 1.0f - ((1.0f - win_bg_col.w) * (1.0f - title_bg_col.w)), k = title_bg_col.w / new_a; return ImVec4((win_bg_col.x * win_bg_col.w + title_bg_col.x) * k, (win_bg_col.y * win_bg_col.w + title_bg_col.y) * k, (win_bg_col.z * win_bg_col.w + title_bg_col.z) * k, new_a); } - If this is confusing, pick the RGB value from title bar from an old screenshot and apply this as TitleBg/TitleBgActive. Or you may just create TitleBgActive from a tweaked TitleBg color. - - 2016/05/07 (1.49) - removed confusing set of GetInternalState(), GetInternalStateSize(), SetInternalState() functions. Now using CreateContext(), DestroyContext(), GetCurrentContext(), SetCurrentContext(). - - 2016/05/02 (1.49) - renamed SetNextTreeNodeOpened() to SetNextTreeNodeOpen(), no redirection. - - 2016/05/01 (1.49) - obsoleted old signature of CollapsingHeader(const char* label, const char* str_id = NULL, bool display_frame = true, bool default_open = false) as extra parameters were badly designed and rarely used. You can replace the "default_open = true" flag in new API with CollapsingHeader(label, ImGuiTreeNodeFlags_DefaultOpen). - - 2016/04/26 (1.49) - changed ImDrawList::PushClipRect(ImVec4 rect) to ImDrawList::PushClipRect(Imvec2 min,ImVec2 max,bool intersect_with_current_clip_rect=false). Note that higher-level ImGui::PushClipRect() is preferable because it will clip at logic/widget level, whereas ImDrawList::PushClipRect() only affect your renderer. - - 2016/04/03 (1.48) - removed style.WindowFillAlphaDefault setting which was redundant. Bake default BG alpha inside style.Colors[ImGuiCol_WindowBg] and all other Bg color values. (ref github issue #337). - - 2016/04/03 (1.48) - renamed ImGuiCol_TooltipBg to ImGuiCol_PopupBg, used by popups/menus and tooltips. popups/menus were previously using ImGuiCol_WindowBg. (ref github issue #337) - - 2016/03/21 (1.48) - renamed GetWindowFont() to GetFont(), GetWindowFontSize() to GetFontSize(). Kept inline redirection function (will obsolete). - - 2016/03/02 (1.48) - InputText() completion/history/always callbacks: if you modify the text buffer manually (without using DeleteChars()/InsertChars() helper) you need to maintain the BufTextLen field. added an assert. - - 2016/01/23 (1.48) - fixed not honoring exact width passed to PushItemWidth(), previously it would add extra FramePadding.x*2 over that width. if you had manual pixel-perfect alignment in place it might affect you. - - 2015/12/27 (1.48) - fixed ImDrawList::AddRect() which used to render a rectangle 1 px too large on each axis. - - 2015/12/04 (1.47) - renamed Color() helpers to ValueColor() - dangerously named, rarely used and probably to be made obsolete. - - 2015/08/29 (1.45) - with the addition of horizontal scrollbar we made various fixes to inconsistencies with dealing with cursor position. - GetCursorPos()/SetCursorPos() functions now include the scrolled amount. It shouldn't affect the majority of users, but take note that SetCursorPosX(100.0f) puts you at +100 from the starting x position which may include scrolling, not at +100 from the window left side. - GetContentRegionMax()/GetWindowContentRegionMin()/GetWindowContentRegionMax() functions allow include the scrolled amount. Typically those were used in cases where no scrolling would happen so it may not be a problem, but watch out! - - 2015/08/29 (1.45) - renamed style.ScrollbarWidth to style.ScrollbarSize - - 2015/08/05 (1.44) - split imgui.cpp into extra files: imgui_demo.cpp imgui_draw.cpp imgui_internal.h that you need to add to your project. - - 2015/07/18 (1.44) - fixed angles in ImDrawList::PathArcTo(), PathArcToFast() (introduced in 1.43) being off by an extra PI for no justifiable reason - - 2015/07/14 (1.43) - add new ImFontAtlas::AddFont() API. For the old AddFont***, moved the 'font_no' parameter of ImFontAtlas::AddFont** functions to the ImFontConfig structure. - you need to render your textured triangles with bilinear filtering to benefit from sub-pixel positioning of text. - - 2015/07/08 (1.43) - switched rendering data to use indexed rendering. this is saving a fair amount of CPU/GPU and enables us to get anti-aliasing for a marginal cost. - this necessary change will break your rendering function! the fix should be very easy. sorry for that :( - - if you are using a vanilla copy of one of the imgui_impl_XXXX.cpp provided in the example, you just need to update your copy and you can ignore the rest. - - the signature of the io.RenderDrawListsFn handler has changed! - old: ImGui_XXXX_RenderDrawLists(ImDrawList** const cmd_lists, int cmd_lists_count) - new: ImGui_XXXX_RenderDrawLists(ImDrawData* draw_data). - parameters: 'cmd_lists' becomes 'draw_data->CmdLists', 'cmd_lists_count' becomes 'draw_data->CmdListsCount' - ImDrawList: 'commands' becomes 'CmdBuffer', 'vtx_buffer' becomes 'VtxBuffer', 'IdxBuffer' is new. - ImDrawCmd: 'vtx_count' becomes 'ElemCount', 'clip_rect' becomes 'ClipRect', 'user_callback' becomes 'UserCallback', 'texture_id' becomes 'TextureId'. - - each ImDrawList now contains both a vertex buffer and an index buffer. For each command, render ElemCount/3 triangles using indices from the index buffer. - - if you REALLY cannot render indexed primitives, you can call the draw_data->DeIndexAllBuffers() method to de-index the buffers. This is slow and a waste of CPU/GPU. Prefer using indexed rendering! - - refer to code in the examples/ folder or ask on the GitHub if you are unsure of how to upgrade. please upgrade! - - 2015/07/10 (1.43) - changed SameLine() parameters from int to float. - - 2015/07/02 (1.42) - renamed SetScrollPosHere() to SetScrollFromCursorPos(). Kept inline redirection function (will obsolete). - - 2015/07/02 (1.42) - renamed GetScrollPosY() to GetScrollY(). Necessary to reduce confusion along with other scrolling functions, because positions (e.g. cursor position) are not equivalent to scrolling amount. - - 2015/06/14 (1.41) - changed ImageButton() default bg_col parameter from (0,0,0,1) (black) to (0,0,0,0) (transparent) - makes a difference when texture have transparence - - 2015/06/14 (1.41) - changed Selectable() API from (label, selected, size) to (label, selected, flags, size). Size override should have been rarely be used. Sorry! - - 2015/05/31 (1.40) - renamed GetWindowCollapsed() to IsWindowCollapsed() for consistency. Kept inline redirection function (will obsolete). - - 2015/05/31 (1.40) - renamed IsRectClipped() to IsRectVisible() for consistency. Note that return value is opposite! Kept inline redirection function (will obsolete). - - 2015/05/27 (1.40) - removed the third 'repeat_if_held' parameter from Button() - sorry! it was rarely used and inconsistent. Use PushButtonRepeat(true) / PopButtonRepeat() to enable repeat on desired buttons. - - 2015/05/11 (1.40) - changed BeginPopup() API, takes a string identifier instead of a bool. ImGui needs to manage the open/closed state of popups. Call OpenPopup() to actually set the "open" state of a popup. BeginPopup() returns true if the popup is opened. - - 2015/05/03 (1.40) - removed style.AutoFitPadding, using style.WindowPadding makes more sense (the default values were already the same). - - 2015/04/13 (1.38) - renamed IsClipped() to IsRectClipped(). Kept inline redirection function until 1.50. - - 2015/04/09 (1.38) - renamed ImDrawList::AddArc() to ImDrawList::AddArcFast() for compatibility with future API - - 2015/04/03 (1.38) - removed ImGuiCol_CheckHovered, ImGuiCol_CheckActive, replaced with the more general ImGuiCol_FrameBgHovered, ImGuiCol_FrameBgActive. - - 2014/04/03 (1.38) - removed support for passing -FLT_MAX..+FLT_MAX as the range for a SliderFloat(). Use DragFloat() or Inputfloat() instead. - - 2015/03/17 (1.36) - renamed GetItemBoxMin()/GetItemBoxMax()/IsMouseHoveringBox() to GetItemRectMin()/GetItemRectMax()/IsMouseHoveringRect(). Kept inline redirection function until 1.50. - - 2015/03/15 (1.36) - renamed style.TreeNodeSpacing to style.IndentSpacing, ImGuiStyleVar_TreeNodeSpacing to ImGuiStyleVar_IndentSpacing - - 2015/03/13 (1.36) - renamed GetWindowIsFocused() to IsWindowFocused(). Kept inline redirection function until 1.50. - - 2015/03/08 (1.35) - renamed style.ScrollBarWidth to style.ScrollbarWidth (casing) - - 2015/02/27 (1.34) - renamed OpenNextNode(bool) to SetNextTreeNodeOpened(bool, ImGuiSetCond). Kept inline redirection function until 1.50. - - 2015/02/27 (1.34) - renamed ImGuiSetCondition_*** to ImGuiSetCond_***, and _FirstUseThisSession becomes _Once. - - 2015/02/11 (1.32) - changed text input callback ImGuiTextEditCallback return type from void-->int. reserved for future use, return 0 for now. - - 2015/02/10 (1.32) - renamed GetItemWidth() to CalcItemWidth() to clarify its evolving behavior - - 2015/02/08 (1.31) - renamed GetTextLineSpacing() to GetTextLineHeightWithSpacing() - - 2015/02/01 (1.31) - removed IO.MemReallocFn (unused) - - 2015/01/19 (1.30) - renamed ImGuiStorage::GetIntPtr()/GetFloatPtr() to GetIntRef()/GetIntRef() because Ptr was conflicting with actual pointer storage functions. - - 2015/01/11 (1.30) - big font/image API change! now loads TTF file. allow for multiple fonts. no need for a PNG loader. - - 2015/01/11 (1.30) - removed GetDefaultFontData(). uses io.Fonts->GetTextureData*() API to retrieve uncompressed pixels. - - old: const void* png_data; unsigned int png_size; ImGui::GetDefaultFontData(NULL, NULL, &png_data, &png_size); [..Upload texture to GPU..]; - - new: unsigned char* pixels; int width, height; io.Fonts->GetTexDataAsRGBA32(&pixels, &width, &height); [..Upload texture to GPU..]; io.Fonts->TexId = YourTexIdentifier; - you now have more flexibility to load multiple TTF fonts and manage the texture buffer for internal needs. It is now recommended that you sample the font texture with bilinear interpolation. - - 2015/01/11 (1.30) - added texture identifier in ImDrawCmd passed to your render function (we can now render images). make sure to set io.Fonts->TexID. - - 2015/01/11 (1.30) - removed IO.PixelCenterOffset (unnecessary, can be handled in user projection matrix) - - 2015/01/11 (1.30) - removed ImGui::IsItemFocused() in favor of ImGui::IsItemActive() which handles all widgets - - 2014/12/10 (1.18) - removed SetNewWindowDefaultPos() in favor of new generic API SetNextWindowPos(pos, ImGuiSetCondition_FirstUseEver) - - 2014/11/28 (1.17) - moved IO.Font*** options to inside the IO.Font-> structure (FontYOffset, FontTexUvForWhite, FontBaseScale, FontFallbackGlyph) - - 2014/11/26 (1.17) - reworked syntax of IMGUI_ONCE_UPON_A_FRAME helper macro to increase compiler compatibility - - 2014/11/07 (1.15) - renamed IsHovered() to IsItemHovered() - - 2014/10/02 (1.14) - renamed IMGUI_INCLUDE_IMGUI_USER_CPP to IMGUI_INCLUDE_IMGUI_USER_INL and imgui_user.cpp to imgui_user.inl (more IDE friendly) - - 2014/09/25 (1.13) - removed 'text_end' parameter from IO.SetClipboardTextFn (the string is now always zero-terminated for simplicity) - - 2014/09/24 (1.12) - renamed SetFontScale() to SetWindowFontScale() - - 2014/09/24 (1.12) - moved IM_MALLOC/IM_REALLOC/IM_FREE preprocessor defines to IO.MemAllocFn/IO.MemReallocFn/IO.MemFreeFn - - 2014/08/30 (1.09) - removed IO.FontHeight (now computed automatically) - - 2014/08/30 (1.09) - moved IMGUI_FONT_TEX_UV_FOR_WHITE preprocessor define to IO.FontTexUvForWhite - - 2014/08/28 (1.09) - changed the behavior of IO.PixelCenterOffset following various rendering fixes - - - FREQUENTLY ASKED QUESTIONS (FAQ) - ================================ - - Read all answers online: https://www.dearimgui.org/faq, or in docs/FAQ.md (with a Markdown viewer) - Some answers are copied down here to facilitate searching in code. - - Q&A: Basics - =========== - - Q: Where is the documentation? - A: This library is poorly documented at the moment and expects of the user to be acquainted with C/C++. - - Run the examples/ and explore them. - - See demo code in imgui_demo.cpp and particularly the ImGui::ShowDemoWindow() function. - - The demo covers most features of Dear ImGui, so you can read the code and see its output. - - See documentation and comments at the top of imgui.cpp + effectively imgui.h. - - Dozens of standalone example applications using e.g. OpenGL/DirectX are provided in the - examples/ folder to explain how to integrate Dear ImGui with your own engine/application. - - The Wiki (https://github.com/ocornut/imgui/wiki) has many resources and links. - - The Glossary (https://github.com/ocornut/imgui/wiki/Glossary) page also may be useful. - - Your programming IDE is your friend, find the type or function declaration to find comments - associated to it. - - Q: What is this library called? - Q: Which version should I get? - >> This library is called "Dear ImGui", please don't call it "ImGui" :) - >> See https://www.dearimgui.org/faq - - Q&A: Integration - ================ - - Q: How can I tell whether to dispatch mouse/keyboard to Dear ImGui or to my application? - A: You should read the 'io.WantCaptureMouse', 'io.WantCaptureKeyboard' and 'io.WantTextInput' flags! - >> See https://www.dearimgui.org/faq for fully detailed answer. You really want to read this. - - Q. How can I enable keyboard controls? - Q: How can I use this without a mouse, without a keyboard or without a screen? (gamepad, input share, remote display) - Q: I integrated Dear ImGui in my engine and the text or lines are blurry.. - Q: I integrated Dear ImGui in my engine and some elements are clipping or disappearing when I move windows around.. - >> See https://www.dearimgui.org/faq - - Q&A: Usage - ---------- - - Q: Why are multiple widgets reacting when I interact with a single one? - Q: How can I have multiple widgets with the same label or with an empty label? - A: A primer on labels and the ID Stack... - - Dear ImGui internally need to uniquely identify UI elements. - Elements that are typically not clickable (such as calls to the Text functions) don't need an ID. - Interactive widgets (such as calls to Button buttons) need a unique ID. - Unique ID are used internally to track active widgets and occasionally associate state to widgets. - Unique ID are implicitly built from the hash of multiple elements that identify the "path" to the UI element. - - - Unique ID are often derived from a string label: - - Button("OK"); // Label = "OK", ID = hash of (..., "OK") - Button("Cancel"); // Label = "Cancel", ID = hash of (..., "Cancel") - - - ID are uniquely scoped within windows, tree nodes, etc. which all pushes to the ID stack. Having - two buttons labeled "OK" in different windows or different tree locations is fine. - We used "..." above to signify whatever was already pushed to the ID stack previously: - - Begin("MyWindow"); - Button("OK"); // Label = "OK", ID = hash of ("MyWindow", "OK") - End(); - Begin("MyOtherWindow"); - Button("OK"); // Label = "OK", ID = hash of ("MyOtherWindow", "OK") - End(); - - - If you have a same ID twice in the same location, you'll have a conflict: - - Button("OK"); - Button("OK"); // ID collision! Interacting with either button will trigger the first one. - - Fear not! this is easy to solve and there are many ways to solve it! - - - Solving ID conflict in a simple/local context: - When passing a label you can optionally specify extra ID information within string itself. - Use "##" to pass a complement to the ID that won't be visible to the end-user. - This helps solving the simple collision cases when you know e.g. at compilation time which items - are going to be created: - - Begin("MyWindow"); - Button("Play"); // Label = "Play", ID = hash of ("MyWindow", "Play") - Button("Play##foo1"); // Label = "Play", ID = hash of ("MyWindow", "Play##foo1") // Different from above - Button("Play##foo2"); // Label = "Play", ID = hash of ("MyWindow", "Play##foo2") // Different from above - End(); - - - If you want to completely hide the label, but still need an ID: - - Checkbox("##On", &b); // Label = "", ID = hash of (..., "##On") // No visible label, just a checkbox! - - - Occasionally/rarely you might want change a label while preserving a constant ID. This allows - you to animate labels. For example you may want to include varying information in a window title bar, - but windows are uniquely identified by their ID. Use "###" to pass a label that isn't part of ID: - - Button("Hello###ID"); // Label = "Hello", ID = hash of (..., "###ID") - Button("World###ID"); // Label = "World", ID = hash of (..., "###ID") // Same as above, even though the label looks different - - sprintf(buf, "My game (%f FPS)###MyGame", fps); - Begin(buf); // Variable title, ID = hash of "MyGame" - - - Solving ID conflict in a more general manner: - Use PushID() / PopID() to create scopes and manipulate the ID stack, as to avoid ID conflicts - within the same window. This is the most convenient way of distinguishing ID when iterating and - creating many UI elements programmatically. - You can push a pointer, a string or an integer value into the ID stack. - Remember that ID are formed from the concatenation of _everything_ pushed into the ID stack. - At each level of the stack we store the seed used for items at this level of the ID stack. - - Begin("Window"); - for (int i = 0; i < 100; i++) - { - PushID(i); // Push i to the id tack - Button("Click"); // Label = "Click", ID = hash of ("Window", i, "Click") - PopID(); - } - for (int i = 0; i < 100; i++) - { - MyObject* obj = Objects[i]; - PushID(obj); - Button("Click"); // Label = "Click", ID = hash of ("Window", obj pointer, "Click") - PopID(); - } - for (int i = 0; i < 100; i++) - { - MyObject* obj = Objects[i]; - PushID(obj->Name); - Button("Click"); // Label = "Click", ID = hash of ("Window", obj->Name, "Click") - PopID(); - } - End(); - - - You can stack multiple prefixes into the ID stack: - - Button("Click"); // Label = "Click", ID = hash of (..., "Click") - PushID("node"); - Button("Click"); // Label = "Click", ID = hash of (..., "node", "Click") - PushID(my_ptr); - Button("Click"); // Label = "Click", ID = hash of (..., "node", my_ptr, "Click") - PopID(); - PopID(); - - - Tree nodes implicitly creates a scope for you by calling PushID(). - - Button("Click"); // Label = "Click", ID = hash of (..., "Click") - if (TreeNode("node")) // <-- this function call will do a PushID() for you (unless instructed not to, with a special flag) - { - Button("Click"); // Label = "Click", ID = hash of (..., "node", "Click") - TreePop(); - } - - - When working with trees, ID are used to preserve the open/close state of each tree node. - Depending on your use cases you may want to use strings, indices or pointers as ID. - e.g. when following a single pointer that may change over time, using a static string as ID - will preserve your node open/closed state when the targeted object change. - e.g. when displaying a list of objects, using indices or pointers as ID will preserve the - node open/closed state differently.

With increased funding we can hire more people working on this project. - - Individuals: you can support continued development via PayPal donations. See README. - - If you are experienced with Dear ImGui and C++, look at the github issues, look at the Wiki, read docs/TODO.txt - and see how you want to help and can help! - - Disclose your usage of Dear ImGui via a dev blog post, a tweet, a screenshot, a mention somewhere etc. - You may post screenshot or links in the gallery threads (github.com/ocornut/imgui/issues/2847). Visuals are ideal as they inspire other programmers. - But even without visuals, disclosing your use of dear imgui help the library grow credibility, and help other teams and programmers with taking decisions. - - If you have issues or if you need to hack into the library, even if you don't expect any support it is useful that you share your issues (on github or privately). - -*/ - -#if defined(_MSC_VER) && !defined(_CRT_SECURE_NO_WARNINGS) -#define _CRT_SECURE_NO_WARNINGS -#endif - -#include "imgui.h" -#ifndef IMGUI_DISABLE - -#ifndef IMGUI_DEFINE_MATH_OPERATORS -#define IMGUI_DEFINE_MATH_OPERATORS -#endif -#include "imgui_internal.h" - -#include // toupper -#include // vsnprintf, sscanf, printf -#if defined(_MSC_VER) && _MSC_VER <= 1500 // MSVC 2008 or earlier -#include // intptr_t -#else -#include // intptr_t -#endif - -// Debug options -#define IMGUI_DEBUG_NAV_SCORING 0 // Display navigation scoring preview when hovering items.

For other of our sources files, they are provided by imgui_internal.h w/ IMGUI_DEFINE_MATH_OPERATORS. -// For your own sources file they are optional and require you either enable those, either provide your own via IM_VEC2_CLASS_EXTRA in imconfig.h. -// Because we don't want to assume anything about your support of maths operators, we don't use them in imgui_demo.cpp. - -/* - -Index of this file: - -// [SECTION] Forward Declarations, Helpers -// [SECTION] Demo Window / ShowDemoWindow() -// [SECTION] About Window / ShowAboutWindow() -// [SECTION] Style Editor / ShowStyleEditor() -// [SECTION] Example App: Main Menu Bar / ShowExampleAppMainMenuBar() -// [SECTION] Example App: Debug Console / ShowExampleAppConsole() -// [SECTION] Example App: Debug Log / ShowExampleAppLog() -// [SECTION] Example App: Simple Layout / ShowExampleAppLayout() -// [SECTION] Example App: Property Editor / ShowExampleAppPropertyEditor() -// [SECTION] Example App: Long Text / ShowExampleAppLongText() -// [SECTION] Example App: Auto Resize / ShowExampleAppAutoResize() -// [SECTION] Example App: Constrained Resize / ShowExampleAppConstrainedResize() -// [SECTION] Example App: Simple Overlay / ShowExampleAppSimpleOverlay() -// [SECTION] Example App: Manipulating Window Titles / ShowExampleAppWindowTitles() -// [SECTION] Example App: Custom Rendering using ImDrawList API / ShowExampleAppCustomRendering() -// [SECTION] Example App: Docking, DockSpace / ShowExampleAppDockSpace() -// [SECTION] Example App: Documents Handling / ShowExampleAppDocuments() - -*/ - -#if defined(_MSC_VER) && !defined(_CRT_SECURE_NO_WARNINGS) -#define _CRT_SECURE_NO_WARNINGS -#endif - -#include "imgui.h" -#ifndef IMGUI_DISABLE - -#include // toupper -#include // INT_MIN, INT_MAX -#include // sqrtf, powf, cosf, sinf, floorf, ceilf -#include // vsnprintf, sscanf, printf -#include // NULL, malloc, free, atoi -#if defined(_MSC_VER) && _MSC_VER <= 1500 // MSVC 2008 or earlier -#include // intptr_t -#else -#include // intptr_t -#endif - -#ifdef _MSC_VER -#pragma warning (disable: 4996) // 'This function or variable may be unsafe': strcpy, strdup, sprintf, vsnprintf, sscanf, fopen -#endif -#if defined(__clang__) -#pragma clang diagnostic ignored "-Wold-style-cast" // warning : use of old-style cast // yes, they are more terse. -#pragma clang diagnostic ignored "-Wdeprecated-declarations" // warning : 'xx' is deprecated: The POSIX name for this item.. // for strdup used in demo code (so user can copy & paste the code) -#pragma clang diagnostic ignored "-Wint-to-void-pointer-cast" // warning : cast to 'void *' from smaller integer type 'int' -#pragma clang diagnostic ignored "-Wformat-security" // warning : warning: format string is not a string literal -#pragma clang diagnostic ignored "-Wexit-time-destructors" // warning : declaration requires an exit-time destructor // exit-time destruction order is undefined. if MemFree() leads to users code that has been disabled before exit it might cause problems.

In this mode, it declares a -// single public symbol, STB_TexteditState, which encapsulates the current -// state of a text widget (except for the string, which you will store -// separately). -// -// To compile in this mode, you must define STB_TEXTEDIT_CHARTYPE to a -// primitive type that defines a single character (e.g. char, wchar_t, etc). -// -// To save space or increase undo-ability, you can optionally define the -// following things that are used by the undo system: -// -// STB_TEXTEDIT_POSITIONTYPE small int type encoding a valid cursor position -// STB_TEXTEDIT_UNDOSTATECOUNT the number of undo states to allow -// STB_TEXTEDIT_UNDOCHARCOUNT the number of characters to store in the undo buffer -// -// If you don't define these, they are set to permissive types and -// moderate sizes. The undo system does no memory allocations, so -// it grows STB_TexteditState by the worst-case storage which is (in bytes): -// -// [4 + 3 * sizeof(STB_TEXTEDIT_POSITIONTYPE)] * STB_TEXTEDIT_UNDOSTATE_COUNT -// + sizeof(STB_TEXTEDIT_CHARTYPE) * STB_TEXTEDIT_UNDOCHAR_COUNT -// -// -// Implementation mode: -// -// If you define STB_TEXTEDIT_IMPLEMENTATION before including this, it -// will compile the implementation of the text edit widget, depending -// on a large number of symbols which must be defined before the include. -// -// The implementation is defined only as static functions. You will then -// need to provide your own APIs in the same file which will access the -// static functions. -// -// The basic concept is that you provide a "string" object which -// behaves like an array of characters. stb_textedit uses indices to -// refer to positions in the string, implicitly representing positions -// in the displayed textedit. This is true for both plain text and -// rich text; even with rich text stb_truetype interacts with your -// code as if there was an array of all the displayed characters. -// -// Symbols that must be the same in header-file and implementation mode: -// -// STB_TEXTEDIT_CHARTYPE the character type -// STB_TEXTEDIT_POSITIONTYPE small type that is a valid cursor position -// STB_TEXTEDIT_UNDOSTATECOUNT the number of undo states to allow -// STB_TEXTEDIT_UNDOCHARCOUNT the number of characters to store in the undo buffer -// -// Symbols you must define for implementation mode: -// -// STB_TEXTEDIT_STRING the type of object representing a string being edited, -// typically this is a wrapper object with other data you need -// -// STB_TEXTEDIT_STRINGLEN(obj) the length of the string (ideally O(1)) -// STB_TEXTEDIT_LAYOUTROW(&r,obj,n) returns the results of laying out a line of characters -// starting from character #n (see discussion below) -// STB_TEXTEDIT_GETWIDTH(obj,n,i) returns the pixel delta from the xpos of the i'th character -// to the xpos of the i+1'th char for a line of characters -// starting at character #n (i.e. accounts for kerning -// with previous char) -// STB_TEXTEDIT_KEYTOTEXT(k) maps a keyboard input to an insertable character -// (return type is int, -1 means not valid to insert) -// STB_TEXTEDIT_GETCHAR(obj,i) returns the i'th character of obj, 0-based -// STB_TEXTEDIT_NEWLINE the character returned by _GETCHAR() we recognize -// as manually wordwrapping for end-of-line positioning -// -// STB_TEXTEDIT_DELETECHARS(obj,i,n) delete n characters starting at i -// STB_TEXTEDIT_INSERTCHARS(obj,i,c*,n) insert n characters at i (pointed to by STB_TEXTEDIT_CHARTYPE*) -// -// STB_TEXTEDIT_K_SHIFT a power of two that is or'd in to a keyboard input to represent the shift key -// -// STB_TEXTEDIT_K_LEFT keyboard input to move cursor left -// STB_TEXTEDIT_K_RIGHT keyboard input to move cursor right -// STB_TEXTEDIT_K_UP keyboard input to move cursor up -// STB_TEXTEDIT_K_DOWN keyboard input to move cursor down -// STB_TEXTEDIT_K_LINESTART keyboard input to move cursor to start of line // e.g. HOME -// STB_TEXTEDIT_K_LINEEND keyboard input to move cursor to end of line // e.g. END -// STB_TEXTEDIT_K_TEXTSTART keyboard input to move cursor to start of text // e.g. ctrl-HOME -// STB_TEXTEDIT_K_TEXTEND keyboard input to move cursor to end of text // e.g. ctrl-END -// STB_TEXTEDIT_K_DELETE keyboard input to delete selection or character under cursor -// STB_TEXTEDIT_K_BACKSPACE keyboard input to delete selection or character left of cursor -// STB_TEXTEDIT_K_UNDO keyboard input to perform undo -// STB_TEXTEDIT_K_REDO keyboard input to perform redo -// -// Optional: -// STB_TEXTEDIT_K_INSERT keyboard input to toggle insert mode -// STB_TEXTEDIT_IS_SPACE(ch) true if character is whitespace (e.g. 'isspace'), -// required for default WORDLEFT/WORDRIGHT handlers -// STB_TEXTEDIT_MOVEWORDLEFT(obj,i) custom handler for WORDLEFT, returns index to move cursor to -// STB_TEXTEDIT_MOVEWORDRIGHT(obj,i) custom handler for WORDRIGHT, returns index to move cursor to -// STB_TEXTEDIT_K_WORDLEFT keyboard input to move cursor left one word // e.g. ctrl-LEFT -// STB_TEXTEDIT_K_WORDRIGHT keyboard input to move cursor right one word // e.g. ctrl-RIGHT -// STB_TEXTEDIT_K_LINESTART2 secondary keyboard input to move cursor to start of line -// STB_TEXTEDIT_K_LINEEND2 secondary keyboard input to move cursor to end of line -// STB_TEXTEDIT_K_TEXTSTART2 secondary keyboard input to move cursor to start of text -// STB_TEXTEDIT_K_TEXTEND2 secondary keyboard input to move cursor to end of text -// -// Todo: -// STB_TEXTEDIT_K_PGUP keyboard input to move cursor up a page -// STB_TEXTEDIT_K_PGDOWN keyboard input to move cursor down a page -// -// Keyboard input must be encoded as a single integer value; e.g. a character code -// and some bitflags that represent shift states. to simplify the interface, SHIFT must -// be a bitflag, so we can test the shifted state of cursor movements to allow selection, -// i.e. (STB_TEXTED_K_RIGHT|STB_TEXTEDIT_K_SHIFT) should be shifted right-arrow. -// -// You can encode other things, such as CONTROL or ALT, in additional bits, and -// then test for their presence in e.g. STB_TEXTEDIT_K_WORDLEFT. For example, -// my Windows implementations add an additional CONTROL bit, and an additional KEYDOWN -// bit. Then all of the STB_TEXTEDIT_K_ values bitwise-or in the KEYDOWN bit, -// and I pass both WM_KEYDOWN and WM_CHAR events to the "key" function in the -// API below. The control keys will only match WM_KEYDOWN events because of the -// keydown bit I add, and STB_TEXTEDIT_KEYTOTEXT only tests for the KEYDOWN -// bit so it only decodes WM_CHAR events. -// -// STB_TEXTEDIT_LAYOUTROW returns information about the shape of one displayed -// row of characters assuming they start on the i'th character--the width and -// the height and the number of characters consumed. This allows this library -// to traverse the entire layout incrementally. You need to compute word-wrapping -// here. -// -// Each textfield keeps its own insert mode state, which is not how normal -// applications work. To keep an app-wide insert mode, update/copy the -// "insert_mode" field of STB_TexteditState before/after calling API functions. -// -// API -// -// void stb_textedit_initialize_state(STB_TexteditState *state, int is_single_line) -// -// void stb_textedit_click(STB_TEXTEDIT_STRING *str, STB_TexteditState *state, float x, float y) -// void stb_textedit_drag(STB_TEXTEDIT_STRING *str, STB_TexteditState *state, float x, float y) -// int stb_textedit_cut(STB_TEXTEDIT_STRING *str, STB_TexteditState *state) -// int stb_textedit_paste(STB_TEXTEDIT_STRING *str, STB_TexteditState *state, STB_TEXTEDIT_CHARTYPE *text, int len) -// void stb_textedit_key(STB_TEXTEDIT_STRING *str, STB_TexteditState *state, STB_TEXEDIT_KEYTYPE key) -// -// Each of these functions potentially updates the string and updates the -// state. -// -// initialize_state: -// set the textedit state to a known good default state when initially -// constructing the textedit. -// -// click: -// call this with the mouse x,y on a mouse down; it will update the cursor -// and reset the selection start/end to the cursor point. the x,y must -// be relative to the text widget, with (0,0) being the top left. -// -// drag: -// call this with the mouse x,y on a mouse drag/up; it will update the -// cursor and the selection end point -// -// cut: -// call this to delete the current selection; returns true if there was -// one. you should FIRST copy the current selection to the system paste buffer. -// (To copy, just copy the current selection out of the string yourself.) -// -// paste: -// call this to paste text at the current cursor point or over the current -// selection if there is one. -// -// key: -// call this for keyboard inputs sent to the textfield. you can use it -// for "key down" events or for "translated" key events. if you need to -// do both (as in Win32), or distinguish Unicode characters from control -// inputs, set a high bit to distinguish the two; then you can define the -// various definitions like STB_TEXTEDIT_K_LEFT have the is-key-event bit -// set, and make STB_TEXTEDIT_KEYTOCHAR check that the is-key-event bit is -// clear. STB_TEXTEDIT_KEYTYPE defaults to int, but you can #define it to -// anything other type you wante before including. -// -// -// When rendering, you can read the cursor position and selection state from -// the STB_TexteditState. -// -// -// Notes: -// -// This is designed to be usable in IMGUI, so it allows for the possibility of -// running in an IMGUI that has NOT cached the multi-line layout. For this -// reason, it provides an interface that is compatible with computing the -// layout incrementally--we try to make sure we make as few passes through -// as possible. (For example, to locate the mouse pointer in the text, we -// could define functions that return the X and Y positions of characters -// and binary search Y and then X, but if we're doing dynamic layout this -// will run the layout algorithm many times, so instead we manually search -// forward in one pass. Similar logic applies to e.g. up-arrow and -// down-arrow movement.) -// -// If it's run in a widget that *has* cached the layout, then this is less -// efficient, but it's not horrible on modern computers. But you wouldn't -// want to edit million-line files with it. - - -//////////////////////////////////////////////////////////////////////////// -//////////////////////////////////////////////////////////////////////////// -//// -//// Header-file mode -//// -//// - -#ifndef INCLUDE_STB_TEXTEDIT_H -#define INCLUDE_STB_TEXTEDIT_H - -//////////////////////////////////////////////////////////////////////// -// -// STB_TexteditState -// -// Definition of STB_TexteditState which you should store -// per-textfield;

Thus, anti-aliasing of intersecting shapes may look wrong. If -// this turns out to be a problem, you can re-enable the old rasterizer with -// #define STBTT_RASTERIZER_VERSION 1 -// which will incur about a 15% speed hit. -// -// ADDITIONAL DOCUMENTATION -// -// Immediately after this block comment are a series of sample programs. -// -// After the sample programs is the "header file" section. This section -// includes documentation for each API function. -// -// Some important concepts to understand to use this library: -// -// Codepoint -// Characters are defined by unicode codepoints, e.g. 65 is -// uppercase A, 231 is lowercase c with a cedilla, 0x7e30 is -// the hiragana for "ma". -// -// Glyph -// A visual character shape (every codepoint is rendered as -// some glyph) -// -// Glyph index -// A font-specific integer ID representing a glyph -// -// Baseline -// Glyph shapes are defined relative to a baseline, which is the -// bottom of uppercase characters. Characters extend both above -// and below the baseline. -// -// Current Point -// As you draw text to the screen, you keep track of a "current point" -// which is the origin of each character. The current point's vertical -// position is the baseline. Even "baked fonts" use this model. -// -// Vertical Font Metrics -// The vertical qualities of the font, used to vertically position -// and space the characters. See docs for stbtt_GetFontVMetrics. -// -// Font Size in Pixels or Points -// The preferred interface for specifying font sizes in stb_truetype -// is to specify how tall the font's vertical extent should be in pixels. -// If that sounds good enough, skip the next paragraph. -// -// Most font APIs instead use "points", which are a common typographic -// measurement for describing font size, defined as 72 points per inch. -// stb_truetype provides a point API for compatibility. However, true -// "per inch" conventions don't make much sense on computer displays -// since different monitors have different number of pixels per -// inch. For example, Windows traditionally uses a convention that -// there are 96 pixels per inch, thus making 'inch' measurements have -// nothing to do with inches, and thus effectively defining a point to -// be 1.333 pixels. Additionally, the TrueType font data provides -// an explicit scale factor to scale a given font's glyphs to points, -// but the author has observed that this scale factor is often wrong -// for non-commercial fonts, thus making fonts scaled in points -// according to the TrueType spec incoherently sized in practice. -// -// DETAILED USAGE: -// -// Scale: -// Select how high you want the font to be, in points or pixels. -// Call ScaleForPixelHeight or ScaleForMappingEmToPixels to compute -// a scale factor SF that will be used by all other functions. -// -// Baseline: -// You need to select a y-coordinate that is the baseline of where -// your text will appear. Call GetFontBoundingBox to get the baseline-relative -// bounding box for all characters. SF*-y0 will be the distance in pixels -// that the worst-case character could extend above the baseline, so if -// you want the top edge of characters to appear at the top of the -// screen where y=0, then you would set the baseline to SF*-y0. -// -// Current point: -// Set the current point where the first character will appear. The -// first character could extend left of the current point; this is font -// dependent. You can either choose a current point that is the leftmost -// point and hope, or add some padding, or check the bounding box or -// left-side-bearing of the first character to be displayed and set -// the current point based on that. -// -// Displaying a character: -// Compute the bounding box of the character. It will contain signed values -// relative to .

It provides a simple, platform-independent API for -creating windows, contexts and surfaces, reading input, handling events, etc. - -GLFW natively supports Windows, macOS and Linux and other Unix-like systems. -Experimental implementations for the Wayland protocol and the Mir display server -are available but not yet officially supported. - -GLFW is licensed under the [zlib/libpng -license](http://www.glfw.org/license.html). - -The latest stable release is version 3.2.1. - -See the [downloads](http://www.glfw.org/download.html) page for details and -files, or fetch the `latest` branch, which always points to the latest stable -release. Each release starting with 3.0 also has a corresponding [annotated -tag](https://github.com/glfw/glfw/releases) with source and binary archives. -The [version history](http://www.glfw.org/changelog.html) lists all user-visible -changes for every release. - -This is a development branch for version 3.3, which is _not yet described_. -Pre-release documentation is available [here](http://www.glfw.org/docs/3.3/). - -The `master` branch is the stable integration branch and _should_ always compile -and run on all supported platforms, although details of newly added features may -change until they have been included in a release. New features and many bug -fixes live in [other branches](https://github.com/glfw/glfw/branches/all) until -they are stable enough to merge. - -If you are new to GLFW, you may find the -[tutorial](http://www.glfw.org/docs/latest/quick.html) for GLFW 3 useful. If -you have used GLFW 2 in the past, there is a [transition -guide](http://www.glfw.org/docs/latest/moving.html) for moving to the GLFW -3 API. - - -## Compiling GLFW - -GLFW itself requires only the headers and libraries for your window system. It -does not need the headers for any context creation API (WGL, GLX, EGL, NSGL, -OSMesa) or rendering API (OpenGL, OpenGL ES, Vulkan) to enable support for them. - -GLFW supports compilation on Windows with Visual C++ 2010 and later, MinGW and -MinGW-w64, on macOS with Clang and on Linux and other Unix-like systems with GCC -and Clang. It will likely compile in other environments as well, but this is -not regularly tested. - -There are [pre-compiled Windows binaries](http://www.glfw.org/download.html) -available for all supported compilers. - -See the [compilation guide](http://www.glfw.org/docs/latest/compile.html) for -more information about how to compile GLFW yourself. - - -## Using GLFW - -See the [documentation](http://www.glfw.org/docs/latest/) for tutorials, guides -and the API reference. - - -## Contributing to GLFW - -See the [contribution -guide](https://github.com/glfw/glfw/blob/master/docs/CONTRIBUTING.md) for -more information. - - -## System requirements - -GLFW supports Windows XP and later and macOS 10.7 and later. Linux and other -Unix-like systems running the X Window System are supported even without -a desktop environment or modern extensions, although some features require -a running window or clipboard manager. The OSMesa backend requires Mesa 6.3. - -See the [compatibility guide](http://www.glfw.org/docs/latest/compat.html) -in the documentation for more information. - - -## Dependencies - -GLFW itself depends only on the headers and libraries for your window system. - -The (experimental) Wayland backend also depends on the `extra-cmake-modules` -package, which is used to generated Wayland protocol headers. - -The examples and test programs depend on a number of tiny libraries. These are -located in the `deps/` directory. - - - [getopt\_port](https://github.com/kimgr/getopt_port/) for examples - with command-line options - - [TinyCThread](https://github.com/tinycthread/tinycthread) for threaded - examples - - An OpenGL 3.2 core loader generated by - [glad](https://github.com/Dav1dde/glad) for examples using modern OpenGL - - [linmath.h](https://github.com/datenwolf/linmath.h) for linear algebra in - examples - - [Nuklear](https://github.com/vurtun/nuklear) for test and example UI - - [stb\_image\_write](https://github.com/nothings/stb) for writing images to disk - - [Vulkan headers](https://www.khronos.org/registry/vulkan/) for Vulkan tests - -The Vulkan example additionally requires the LunarG Vulkan SDK to be installed, -or it will not be included in the build. On macOS you need to provide the path -to the SDK manually as it has no standard installation location. - -The documentation is generated with [Doxygen](http://doxygen.org/) if CMake can -find that tool. - - -## Reporting bugs - -Bugs are reported to our [issue tracker](https://github.com/glfw/glfw/issues). -Please check the [contribution -guide](https://github.com/glfw/glfw/blob/master/docs/CONTRIBUTING.md) for -information on what to include when reporting a bug. -

ANSI C or ISO C90) - - Small codebase (~18kLOC) - - Focus on portability, efficiency and simplicity - - No dependencies (not even the standard library if not wanted) - - Fully skinnable and customizable - - Low memory footprint with total memory control if needed or wanted - - UTF-8 support - - No global or hidden state - - Customizable library modules (you can compile and use only what you need) - - Optional font baker and vertex buffer output - -USAGE: - This library is self contained in one single header file and can be used either - in header only mode or in implementation mode. The header only mode is used - by default when included and allows including this header in other headers - and does not contain the actual implementation. - - The implementation mode requires to define the preprocessor macro - NK_IMPLEMENTATION in *one* .c/.cpp file before #includeing this file, e.g.: - - #define NK_IMPLEMENTATION - #include "nuklear.h" - - Also optionally define the symbols listed in the section "OPTIONAL DEFINES" - below in header and implementation mode if you want to use additional functionality - or need more control over the library. - IMPORTANT: Every time you include "nuklear.h" you have to define the same flags. - This is very important not doing it either leads to compiler errors - or even worse stack corruptions. - -FEATURES: - - Absolutely no platform dependent code - - Memory management control ranging from/to - - Ease of use by allocating everything from standard library - - Control every byte of memory inside the library - - Font handling control ranging from/to - - Use your own font implementation for everything - - Use this libraries internal font baking and handling API - - Drawing output control ranging from/to - - Simple shapes for more high level APIs which already have drawing capabilities - - Hardware accessible anti-aliased vertex buffer output - - Customizable colors and properties ranging from/to - - Simple changes to color by filling a simple color table - - Complete control with ability to use skinning to decorate widgets - - Bendable UI library with widget ranging from/to - - Basic widgets like buttons, checkboxes, slider, ... - - Advanced widget like abstract comboboxes, contextual menus,... - - Compile time configuration to only compile what you need - - Subset which can be used if you do not want to link or use the standard library - - Can be easily modified to only update on user input instead of frame updates - -OPTIONAL DEFINES: - NK_PRIVATE - If defined declares all functions as static, so they can only be accessed - inside the file that contains the implementation - - NK_INCLUDE_FIXED_TYPES - If defined it will include header for fixed sized types - otherwise nuklear tries to select the correct type. If that fails it will - throw a compiler error and you have to select the correct types yourself. - If used needs to be defined for implementation and header - - NK_INCLUDE_DEFAULT_ALLOCATOR - if defined it will include header and provide additional functions - to use this library without caring for memory allocation control and therefore - ease memory management. - Adds the standard library with malloc and free so don't define if you - don't want to link to the standard library - If used needs to be defined for implementation and header - - NK_INCLUDE_STANDARD_IO - if defined it will include header and provide - additional functions depending on file loading. - Adds the standard library with fopen, fclose,... so don't define this - if you don't want to link to the standard library - If used needs to be defined for implementation and header - - NK_INCLUDE_STANDARD_VARARGS - if defined it will include header and provide - additional functions depending on variable arguments - Adds the standard library with va_list and so don't define this if - you don't want to link to the standard library - If used needs to be defined for implementation and header - - NK_INCLUDE_VERTEX_BUFFER_OUTPUT - Defining this adds a vertex draw command list backend to this - library, which allows you to convert queue commands into vertex draw commands. - This is mainly if you need a hardware accessible format for OpenGL, DirectX, - Vulkan, Metal,... - If used needs to be defined for implementation and header - - NK_INCLUDE_FONT_BAKING - Defining this adds `stb_truetype` and `stb_rect_pack` implementation - to this library and provides font baking and rendering. - If you already have font handling or do not want to use this font handler - you don't have to define it. - If used needs to be defined for implementation and header - - NK_INCLUDE_DEFAULT_FONT - Defining this adds the default font: ProggyClean.ttf into this library - which can be loaded into a font atlas and allows using this library without - having a truetype font - Enabling this adds ~12kb to global stack memory - If used needs to be defined for implementation and header - - NK_INCLUDE_COMMAND_USERDATA - Defining this adds a userdata pointer into each command. Can be useful for - example if you want to provide custom shaders depending on the used widget. - Can be combined with the style structures. - If used needs to be defined for implementation and header - - NK_BUTTON_TRIGGER_ON_RELEASE - Different platforms require button clicks occurring either on buttons being - pressed (up to down) or released (down to up). - By default this library will react on buttons being pressed, but if you - define this it will only trigger if a button is released. - If used it is only required to be defined for the implementation part - - NK_ZERO_COMMAND_MEMORY - Defining this will zero out memory for each drawing command added to a - drawing queue (inside nk_command_buffer_push). Zeroing command memory - is very useful for fast checking (using memcmp) if command buffers are - equal and avoid drawing frames when nothing on screen has changed since - previous frame. - - NK_ASSERT - If you don't define this, nuklear will use with assert(). - Adds the standard library so define to nothing of not wanted - If used needs to be defined for implementation and header - - NK_BUFFER_DEFAULT_INITIAL_SIZE - Initial buffer size allocated by all buffers while using the default allocator - functions included by defining NK_INCLUDE_DEFAULT_ALLOCATOR. If you don't - want to allocate the default 4k memory then redefine it. - If used needs to be defined for implementation and header - - NK_MAX_NUMBER_BUFFER - Maximum buffer size for the conversion buffer between float and string - Under normal circumstances this should be more than sufficient. - If used needs to be defined for implementation and header - - NK_INPUT_MAX - Defines the max number of bytes which can be added as text input in one frame. - Under normal circumstances this should be more than sufficient. - If used it is only required to be defined for the implementation part - - NK_MEMSET - You can define this to 'memset' or your own memset implementation - replacement. If not nuklear will use its own version. - If used it is only required to be defined for the implementation part - - NK_MEMCPY - You can define this to 'memcpy' or your own memcpy implementation - replacement. If not nuklear will use its own version. - If used it is only required to be defined for the implementation part - - NK_SQRT - You can define this to 'sqrt' or your own sqrt implementation - replacement. If not nuklear will use its own slow and not highly - accurate version. - If used it is only required to be defined for the implementation part - - NK_SIN - You can define this to 'sinf' or your own sine implementation - replacement. If not nuklear will use its own approximation implementation. - If used it is only required to be defined for the implementation part - - NK_COS - You can define this to 'cosf' or your own cosine implementation - replacement. If not nuklear will use its own approximation implementation. - If used it is only required to be defined for the implementation part - - NK_STRTOD - You can define this to `strtod` or your own string to double conversion - implementation replacement. If not defined nuklear will use its own - imprecise and possibly unsafe version (does not handle nan or infinity!). - If used it is only required to be defined for the implementation part - - NK_DTOA - You can define this to `dtoa` or your own double to string conversion - implementation replacement. If not defined nuklear will use its own - imprecise and possibly unsafe version (does not handle nan or infinity!). - If used it is only required to be defined for the implementation part - - NK_VSNPRINTF - If you define `NK_INCLUDE_STANDARD_VARARGS` as well as `NK_INCLUDE_STANDARD_IO` - and want to be safe define this to `vsnprintf` on compilers supporting - later versions of C or C++. By default nuklear will check for your stdlib version - in C as well as compiler version in C++. if `vsnprintf` is available - it will define it to `vsnprintf` directly. If not defined and if you have - older versions of C or C++ it will be defined to `vsprintf` which is unsafe. - If used it is only required to be defined for the implementation part - - NK_BYTE - NK_INT16 - NK_UINT16 - NK_INT32 - NK_UINT32 - NK_SIZE_TYPE - NK_POINTER_TYPE - If you compile without NK_USE_FIXED_TYPE then a number of standard types - will be selected and compile time validated.

-/* ============================================================================= - * - * LAYOUT - * - * ============================================================================= */ -/* Layouting in general describes placing widget inside a window with position and size. - * While in this particular implementation there are five different APIs for layouting - * each with different trade offs between control and ease of use. - * - * All layouting methods in this library are based around the concept of a row. - * A row has a height the window content grows by and a number of columns and each - * layouting method specifies how each widget is placed inside the row. - * After a row has been allocated by calling a layouting functions and then - * filled with widgets will advance an internal pointer over the allocated row. - * - * To actually define a layout you just call the appropriate layouting function - * and each subsequent widget call will place the widget as specified. Important - * here is that if you define more widgets then columns defined inside the layout - * functions it will allocate the next row without you having to make another layouting - * call. - * - * Biggest limitation with using all these APIs outside the `nk_layout_space_xxx` API - * is that you have to define the row height for each. However the row height - * often depends on the height of the font. - * - * To fix that internally nuklear uses a minimum row height that is set to the - * height plus padding of currently active font and overwrites the row height - * value if zero. - * - * If you manually want to change the minimum row height then - * use nk_layout_set_min_row_height, and use nk_layout_reset_min_row_height to - * reset it back to be derived from font height. - * - * Also if you change the font in nuklear it will automatically change the minimum - * row height for you and. This means if you change the font but still want - * a minimum row height smaller than the font you have to repush your value. - * - * For actually more advanced UI I would even recommend using the `nk_layout_space_xxx` - * layouting method in combination with a cassowary constraint solver (there are - * some versions on github with permissive license model) to take over all control over widget - * layouting yourself. However for quick and dirty layouting using all the other layouting - * functions should be fine. - * - * Usage - * ------------------- - * 1.) nk_layout_row_dynamic - * The easiest layouting function is `nk_layout_row_dynamic`. It provides each - * widgets with same horizontal space inside the row and dynamically grows - * if the owning window grows in width. So the number of columns dictates - * the size of each widget dynamically by formula: - * - * widget_width = (window_width - padding - spacing) * (1/colum_count) - * - * Just like all other layouting APIs if you define more widget than columns this - * library will allocate a new row and keep all layouting parameters previously - * defined. - * - * if (nk_begin_xxx(...) { - * // first row with height: 30 composed of two widgets - * nk_layout_row_dynamic(&ctx, 30, 2); - * nk_widget(...); - * nk_widget(...); - * - * // second row with same parameter as defined above - * nk_widget(...); - * nk_widget(...); - * - * // third row uses 0 for height which will use auto layouting - * nk_layout_row_dynamic(&ctx, 0, 2); - * nk_widget(...); - * nk_widget(...); - * } - * nk_end(...); - * - * 2.) nk_layout_row_static - * Another easy layouting function is `nk_layout_row_static`. It provides each - * widget with same horizontal pixel width inside the row and does not grow - * if the owning window scales smaller or bigger. - * - * if (nk_begin_xxx(...) { - * // first row with height: 30 composed of two widgets with width: 80 - * nk_layout_row_static(&ctx, 30, 80, 2); - * nk_widget(...); - * nk_widget(...); - * - * // second row with same parameter as defined above - * nk_widget(...); - * nk_widget(...); - * - * // third row uses 0 for height which will use auto layouting - * nk_layout_row_static(&ctx, 0, 80, 2); - * nk_widget(...); - * nk_widget(...); - * } - * nk_end(...); - * - * 3.) nk_layout_row_xxx - * A little bit more advanced layouting API are functions `nk_layout_row_begin`, - * `nk_layout_row_push` and `nk_layout_row_end`. They allow to directly - * specify each column pixel or window ratio in a row. It supports either - * directly setting per column pixel width or widget window ratio but not - * both. Furthermore it is a immediate mode API so each value is directly - * pushed before calling a widget. Therefore the layout is not automatically - * repeating like the last two layouting functions. - * - * if (nk_begin_xxx(...) { - * // first row with height: 25 composed of two widgets with width 60 and 40 - * nk_layout_row_begin(ctx, NK_STATIC, 25, 2); - * nk_layout_row_push(ctx, 60); - * nk_widget(...); - * nk_layout_row_push(ctx, 40); - * nk_widget(...); - * nk_layout_row_end(ctx); - * - * // second row with height: 25 composed of two widgets with window ratio 0.25 and 0.75 - * nk_layout_row_begin(ctx, NK_DYNAMIC, 25, 2); - * nk_layout_row_push(ctx, 0.25f); - * nk_widget(...); - * nk_layout_row_push(ctx, 0.75f); - * nk_widget(...); - * nk_layout_row_end(ctx); - * - * // third row with auto generated height: composed of two widgets with window ratio 0.25 and 0.75 - * nk_layout_row_begin(ctx, NK_DYNAMIC, 0, 2); - * nk_layout_row_push(ctx, 0.25f); - * nk_widget(...); - * nk_layout_row_push(ctx, 0.75f); - * nk_widget(...); - * nk_layout_row_end(ctx); - * } - * nk_end(...); - * - * 4.) nk_layout_row - * The array counterpart to API nk_layout_row_xxx is the single nk_layout_row - * functions. Instead of pushing either pixel or window ratio for every widget - * it allows to define it by array. The trade of for less control is that - * `nk_layout_row` is automatically repeating. Otherwise the behavior is the - * same. - * - * if (nk_begin_xxx(...) { - * // two rows with height: 30 composed of two widgets with width 60 and 40 - * const float size[] = {60,40}; - * nk_layout_row(ctx, NK_STATIC, 30, 2, ratio); - * nk_widget(...); - * nk_widget(...); - * nk_widget(...); - * nk_widget(...); - * - * // two rows with height: 30 composed of two widgets with window ratio 0.25 and 0.75 - * const float ratio[] = {0.25, 0.75}; - * nk_layout_row(ctx, NK_DYNAMIC, 30, 2, ratio); - * nk_widget(...); - * nk_widget(...); - * nk_widget(...); - * nk_widget(...); - * - * // two rows with auto generated height composed of two widgets with window ratio 0.25 and 0.75 - * const float ratio[] = {0.25, 0.75}; - * nk_layout_row(ctx, NK_DYNAMIC, 30, 2, ratio); - * nk_widget(...); - * nk_widget(...); - * nk_widget(...); - * nk_widget(...); - * } - * nk_end(...); - * - * 5.) nk_layout_row_template_xxx - * The most complex and second most flexible API is a simplified flexbox version without - * line wrapping and weights for dynamic widgets. It is an immediate mode API but - * unlike `nk_layout_row_xxx` it has auto repeat behavior and needs to be called - * before calling the templated widgets. - * The row template layout has three different per widget size specifier. The first - * one is the static widget size specifier with fixed widget pixel width. They do - * not grow if the row grows and will always stay the same. The second size - * specifier is nk_layout_row_template_push_variable which defines a - * minimum widget size but it also can grow if more space is available not taken - * by other widgets. Finally there are dynamic widgets which are completely flexible - * and unlike variable widgets can even shrink to zero if not enough space - * is provided. - * - * if (nk_begin_xxx(...) { - * // two rows with height: 30 composed of three widgets - * nk_layout_row_template_begin(ctx, 30); - * nk_layout_row_template_push_dynamic(ctx); - * nk_layout_row_template_push_variable(ctx, 80); - * nk_layout_row_template_push_static(ctx, 80); - * nk_layout_row_template_end(ctx); - * - * nk_widget(...); // dynamic widget can go to zero if not enough space - * nk_widget(...); // variable widget with min 80 pixel but can grow bigger if enough space - * nk_widget(...); // static widget with fixed 80 pixel width - * - * // second row same layout - * nk_widget(...); - * nk_widget(...); - * nk_widget(...); - * } - * nk_end(...); - * - * 6.) nk_layout_space_xxx - * Finally the most flexible API directly allows you to place widgets inside the - * window. The space layout API is an immediate mode API which does not support - * row auto repeat and directly sets position and size of a widget.

-/* =============================================================== - * - * FONT - * - * ===============================================================*/ -/* Font handling in this library was designed to be quite customizable and lets - you decide what you want to use and what you want to provide. There are three - different ways to use the font atlas. The first two will use your font - handling scheme and only requires essential data to run nuklear. The next - slightly more advanced features is font handling with vertex buffer output. - Finally the most complex API wise is using nuklear's font baking API. - - 1.) Using your own implementation without vertex buffer output - -------------------------------------------------------------- - So first up the easiest way to do font handling is by just providing a - `nk_user_font` struct which only requires the height in pixel of the used - font and a callback to calculate the width of a string. This way of handling - fonts is best fitted for using the normal draw shape command API where you - do all the text drawing yourself and the library does not require any kind - of deeper knowledge about which font handling mechanism you use. - IMPORTANT: the `nk_user_font` pointer provided to nuklear has to persist - over the complete life time! I know this sucks but it is currently the only - way to switch between fonts. - - float your_text_width_calculation(nk_handle handle, float height, const char *text, int len) - { - your_font_type *type = handle.ptr; - float text_width = ...; - return text_width; - } - - struct nk_user_font font; - font.userdata.ptr = &your_font_class_or_struct; - font.height = your_font_height; - font.width = your_text_width_calculation; - - struct nk_context ctx; - nk_init_default(&ctx, &font); - - 2.) Using your own implementation with vertex buffer output - -------------------------------------------------------------- - While the first approach works fine if you don't want to use the optional - vertex buffer output it is not enough if you do. To get font handling working - for these cases you have to provide two additional parameters inside the - `nk_user_font`. First a texture atlas handle used to draw text as subimages - of a bigger font atlas texture and a callback to query a character's glyph - information (offset, size, ...). So it is still possible to provide your own - font and use the vertex buffer output. - - float your_text_width_calculation(nk_handle handle, float height, const char *text, int len) - { - your_font_type *type = handle.ptr; - float text_width = ...; - return text_width; - } - void query_your_font_glyph(nk_handle handle, float font_height, struct nk_user_font_glyph *glyph, nk_rune codepoint, nk_rune next_codepoint) - { - your_font_type *type = handle.ptr; - glyph.width = ...; - glyph.height = ...; - glyph.xadvance = ...; - glyph.uv[0].x = ...; - glyph.uv[0].y = ...; - glyph.uv[1].x = ...; - glyph.uv[1].y = ...; - glyph.offset.x = ...; - glyph.offset.y = ...; - } - - struct nk_user_font font; - font.userdata.ptr = &your_font_class_or_struct; - font.height = your_font_height; - font.width = your_text_width_calculation; - font.query = query_your_font_glyph; - font.texture.id = your_font_texture; - - struct nk_context ctx; - nk_init_default(&ctx, &font); - - 3.) Nuklear font baker - ------------------------------------ - The final approach if you do not have a font handling functionality or don't - want to use it in this library is by using the optional font baker. - The font baker APIs can be used to create a font plus font atlas texture - and can be used with or without the vertex buffer output. - - It still uses the `nk_user_font` struct and the two different approaches - previously stated still work. The font baker is not located inside - `nk_context` like all other systems since it can be understood as more of - an extension to nuklear and does not really depend on any `nk_context` state. - - Font baker need to be initialized first by one of the nk_font_atlas_init_xxx - functions. If you don't care about memory just call the default version - `nk_font_atlas_init_default` which will allocate all memory from the standard library. - If you want to control memory allocation but you don't care if the allocated - memory is temporary and therefore can be freed directly after the baking process - is over or permanent you can call `nk_font_atlas_init`. - - After successfully initializing the font baker you can add Truetype(.ttf) fonts from - different sources like memory or from file by calling one of the `nk_font_atlas_add_xxx`. - functions. Adding font will permanently store each font, font config and ttf memory block(!) - inside the font atlas and allows to reuse the font atlas. If you don't want to reuse - the font baker by for example adding additional fonts you can call - `nk_font_atlas_cleanup` after the baking process is over (after calling nk_font_atlas_end). - - As soon as you added all fonts you wanted you can now start the baking process - for every selected glyph to image by calling `nk_font_atlas_bake`. - The baking process returns image memory, width and height which can be used to - either create your own image object or upload it to any graphics library. - No matter which case you finally have to call `nk_font_atlas_end` which - will free all temporary memory including the font atlas image so make sure - you created our texture beforehand. `nk_font_atlas_end` requires a handle - to your font texture or object and optionally fills a `struct nk_draw_null_texture` - which can be used for the optional vertex output. If you don't want it just - set the argument to `NULL`. - - At this point you are done and if you don't want to reuse the font atlas you - can call `nk_font_atlas_cleanup` to free all truetype blobs and configuration - memory. Finally if you don't use the font atlas and any of it's fonts anymore - you need to call `nk_font_atlas_clear` to free all memory still being used. - - struct nk_font_atlas atlas; - nk_font_atlas_init_default(&atlas); - nk_font_atlas_begin(&atlas); - nk_font *font = nk_font_atlas_add_from_file(&atlas, "Path/To/Your/TTF_Font.ttf", 13, 0); - nk_font *font2 = nk_font_atlas_add_from_file(&atlas, "Path/To/Your/TTF_Font2.ttf", 16, 0); - const void* img = nk_font_atlas_bake(&atlas, &img_width, &img_height, NK_FONT_ATLAS_RGBA32); - nk_font_atlas_end(&atlas, nk_handle_id(texture), 0); - - struct nk_context ctx; - nk_init_default(&ctx, &font->handle); - while (1) { - - } - nk_font_atlas_clear(&atlas); - - The font baker API is probably the most complex API inside this library and - I would suggest reading some of my examples `example/` to get a grip on how - to use the font atlas. There are a number of details I left out. For example - how to merge fonts, configure a font with `nk_font_config` to use other languages, - use another texture coordinate format and a lot more: - - struct nk_font_config cfg = nk_font_config(font_pixel_height); - cfg.merge_mode = nk_false or nk_true; - cfg.range = nk_font_korean_glyph_ranges(); - cfg.coord_type = NK_COORD_PIXEL; - nk_font *font = nk_font_atlas_add_from_file(&atlas, "Path/To/Your/TTF_Font.ttf", 13, &cfg);

Of course using the fixed size API removes the - ability to automatically resize a buffer if not enough memory is provided so - you have to take over the resizing. While being a fixed sized buffer sounds - quite limiting, it is very effective in this library since the actual memory - consumption is quite stable and has a fixed upper bound for a lot of cases. - - If you don't want to think about how much memory the library should allocate - at all time or have a very dynamic UI with unpredictable memory consumption - habits but still want control over memory allocation you can use the dynamic - allocator based API.

use at your own risk - - Before #including, - - #define STB_IMAGE_WRITE_IMPLEMENTATION - - in the file that you want to have the implementation. - - Will probably not work correctly with strict-aliasing optimizations. - -ABOUT: - - This header file is a library for writing images to C stdio. It could be - adapted to write to memory or a general streaming interface; let me know. - - The PNG output is not optimal; it is 20-50% larger than the file - written by a decent optimizing implementation. This library is designed - for source code compactness and simplicity, not optimal image file size - or run-time performance. - -BUILDING: - - You can #define STBIW_ASSERT(x) before the #include to avoid using assert.h. - You can #define STBIW_MALLOC(), STBIW_REALLOC(), and STBIW_FREE() to replace - malloc,realloc,free. - You can define STBIW_MEMMOVE() to replace memmove() - -USAGE: - - There are four functions, one for each image file format: - - int stbi_write_png(char const *filename, int w, int h, int comp, const void *data, int stride_in_bytes); - int stbi_write_bmp(char const *filename, int w, int h, int comp, const void *data); - int stbi_write_tga(char const *filename, int w, int h, int comp, const void *data); - int stbi_write_hdr(char const *filename, int w, int h, int comp, const float *data); - - There are also four equivalent functions that use an arbitrary write function. You are - expected to open/close your file-equivalent before and after calling these: - - int stbi_write_png_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const void *data, int stride_in_bytes); - int stbi_write_bmp_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const void *data); - int stbi_write_tga_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const void *data); - int stbi_write_hdr_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const float *data); - - where the callback is: - void stbi_write_func(void *context, void *data, int size); - - You can define STBI_WRITE_NO_STDIO to disable the file variant of these - functions, so the library will not use stdio.h at all. However, this will - also disable HDR writing, because it requires stdio for formatted output. - - Each function returns 0 on failure and non-0 on success. - - The functions create an image file defined by the parameters. The image - is a rectangle of pixels stored from left-to-right, top-to-bottom. - Each pixel contains 'comp' channels of data stored interleaved with 8-bits - per channel, in the following order: 1=Y, 2=YA, 3=RGB, 4=RGBA. (Y is - monochrome color.) The rectangle is 'w' pixels wide and 'h' pixels tall. - The *data pointer points to the first byte of the top-left-most pixel. - For PNG, "stride_in_bytes" is the distance in bytes from the first byte of - a row of pixels to the first byte of the next row of pixels. - - PNG creates output files with the same number of components as the input. - The BMP format expands Y to RGB in the file format and does not - output alpha. - - PNG supports writing rectangles of data even when the bytes storing rows of - data are not consecutive in memory (e.g. sub-rectangles of a larger image), - by supplying the stride between the beginning of adjacent rows. The other - formats do not. (Thus you cannot write a native-format BMP through the BMP - writer, both because it is in BGR order and because it may have padding - at the end of the line.) - - HDR expects linear float data. Since the format is always 32-bit rgb(e) - data, alpha (if provided) is discarded, and for monochrome data it is - replicated across all three channels. - - TGA supports RLE or non-RLE compressed data. To use non-RLE-compressed - data, set the global variable 'stbi_write_tga_with_rle' to 0. - -CREDITS: - - PNG/BMP/TGA - Sean Barrett - HDR - Baldur Karlsson - TGA monochrome: - Jean-Sebastien Guay - misc enhancements: - Tim Kelsey - TGA RLE - Alan Hickman - initial file IO callback implementation - Emmanuel Julien - bugfixes: - github:Chribba - Guillaume Chereau - github:jry2 - github:romigrou - Sergio Gonzalez - Jonas Karlsson - Filip Wasil - Thatcher Ulrich - -LICENSE - -This software is dual-licensed to the public domain and under the following -license: you are granted a perpetual, irrevocable license to copy, modify, -publish, and distribute this file as you see fit. - -*/ - -#ifndef INCLUDE_STB_IMAGE_WRITE_H -#define INCLUDE_STB_IMAGE_WRITE_H - -#ifdef __cplusplus -extern "C" { -#endif - -#ifdef STB_IMAGE_WRITE_STATIC -#define STBIWDEF static -#else -#define STBIWDEF extern -extern int stbi_write_tga_with_rle; -#endif - -#ifndef STBI_WRITE_NO_STDIO -STBIWDEF int stbi_write_png(char const *filename, int w, int h, int comp, const void *data, int stride_in_bytes); -STBIWDEF int stbi_write_bmp(char const *filename, int w, int h, int comp, const void *data); -STBIWDEF int stbi_write_tga(char const *filename, int w, int h, int comp, const void *data); -STBIWDEF int stbi_write_hdr(char const *filename, int w, int h, int comp, const float *data); -#endif - -typedef void stbi_write_func(void *context, void *data, int size); - -STBIWDEF int stbi_write_png_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const void *data, int stride_in_bytes); -STBIWDEF int stbi_write_bmp_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const void *data); -STBIWDEF int stbi_write_tga_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const void *data); -STBIWDEF int stbi_write_hdr_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const float *data); - -#ifdef __cplusplus -} -#endif - -#endif//INCLUDE_STB_IMAGE_WRITE_H - -#ifdef STB_IMAGE_WRITE_IMPLEMENTATION - -#ifdef _WIN32 - #ifndef _CRT_SECURE_NO_WARNINGS - #define _CRT_SECURE_NO_WARNINGS - #endif - #ifndef _CRT_NONSTDC_NO_DEPRECATE - #define _CRT_NONSTDC_NO_DEPRECATE - #endif -#endif - -#ifndef STBI_WRITE_NO_STDIO -#include -#endif // STBI_WRITE_NO_STDIO - -#include -#include -#include -#include - -#if defined(STBIW_MALLOC) && defined(STBIW_FREE) && (defined(STBIW_REALLOC) || defined(STBIW_REALLOC_SIZED)) -// ok -#elif !defined(STBIW_MALLOC) && !defined(STBIW_FREE) && !defined(STBIW_REALLOC) && !defined(STBIW_REALLOC_SIZED) -// ok -#else -#error "Must define all or none of STBIW_MALLOC, STBIW_FREE, and STBIW_REALLOC (or STBIW_REALLOC_SIZED)." -#endif - -#ifndef STBIW_MALLOC -#define STBIW_MALLOC(sz) malloc(sz) -#define STBIW_REALLOC(p,newsz) realloc(p,newsz) -#define STBIW_FREE(p) free(p) -#endif - -#ifndef STBIW_REALLOC_SIZED -#define STBIW_REALLOC_SIZED(p,oldsz,newsz) STBIW_REALLOC(p,newsz) -#endif - - -#ifndef STBIW_MEMMOVE -#define STBIW_MEMMOVE(a,b,sz) memmove(a,b,sz) -#endif - - -#ifndef STBIW_ASSERT -#include -#define STBIW_ASSERT(x) assert(x) -#endif - -#define STBIW_UCHAR(x) (unsigned char) ((x) & 0xff) - -typedef struct -{ - stbi_write_func *func; - void *context; -} stbi__write_context; - -// initialize a callback-based context -static void stbi__start_write_callbacks(stbi__write_context *s, stbi_write_func *c, void *context) -{ - s->func = c; - s->context = context; -} - -#ifndef STBI_WRITE_NO_STDIO - -static void stbi__stdio_write(void *context, void *data, int size) -{ - fwrite(data,1,size,(FILE*) context); -} - -static int stbi__start_write_file(stbi__write_context *s, const char *filename) -{ - FILE *f = fopen(filename, "wb"); - stbi__start_write_callbacks(s, stbi__stdio_write, (void *) f); - return f != NULL; -} - -static void stbi__end_write_file(stbi__write_context *s) -{ - fclose((FILE *)s->context); -} - -#endif // !STBI_WRITE_NO_STDIO - -typedef unsigned int stbiw_uint32; -typedef int stb_image_write_test[sizeof(stbiw_uint32)==4 ?

- -## Asking a question - -Questions about how to use GLFW should be asked either in the [support -section](http://discourse.glfw.org/c/support) of the forum, under the [Stack -Overflow tag](https://stackoverflow.com/questions/tagged/glfw) or [Game -Development tag](https://gamedev.stackexchange.com/questions/tagged/glfw) on -Stack Exchange or in the IRC channel `#glfw` on -[Freenode](http://freenode.net/). - -Questions about the design or implementation of GLFW or about future plans -should be asked in the [dev section](http://discourse.glfw.org/c/dev) of the -forum or in the IRC channel. Please don't open a GitHub issue to discuss design -questions without first checking with a maintainer. - - -## Reporting a bug - -If GLFW is behaving unexpectedly at run-time, start by setting an [error -callback](http://www.glfw.org/docs/latest/intro_guide.html#error_handling). -GLFW will often tell you the cause of an error via this callback. If it -doesn't, that might be a separate bug. - -If GLFW is crashing or triggering asserts, make sure that all your object -handles and other pointers are valid. - -For bugs where it makes sense, a short, self contained example is absolutely -invaluable. Just put it inline in the body text. Note that if the bug is -reproducible with one of the test programs that come with GLFW, just mention -that instead. - -__Don't worry about adding too much information__. Unimportant information can -be abbreviated or removed later, but missing information can stall bug fixing, -especially when your schedule doesn't align with that of the maintainer. - -__Please provide text as text, not as images__. This includes code, error -messages and any other text. Text in images cannot be found by other users -searching for the same problem and may have to be re-typed by maintainers when -debugging. - -You don't need to manually indent your code or other text to quote it with -GitHub Markdown; just surround it with triple backticks: - - ``` - Some quoted text. - ``` - -You can also add syntax highlighting by appending the common file extension: - - ```c - int five(void) - { - return 5; - } - ``` - -There are issue labels for both platforms and GPU manufacturers, so there is no -need to mention these in the subject line. If you do, it will be removed when -the issue is labeled. - -If your bug is already reported, please add any new information you have, or if -it already has everything, give it a :+1:. - - -### Reporting a compile or link bug - -__Note:__ GLFW needs many system APIs to do its job, which on some platforms -means linking to many system libraries. If you are using GLFW as a static -library, that means your application needs to link to these in addition to GLFW. - -__Note:__ Check the [Compiling -GLFW](http://www.glfw.org/docs/latest/compile.html) guide and or [Building -applications](http://www.glfw.org/docs/latest/build.html) guide for before -opening an issue of this kind. Most issues are caused by a missing package or -linker flag. - -Always include the __operating system name and version__ (e.g. `Windows -7 64-bit` or `Ubuntu 15.10`) and the __compiler name and version__ (e.g. `Visual -C++ 2015 Update 2`). If you are using an official release of GLFW, -include the __GLFW release version__ (e.g. `3.1.2`), otherwise include the -__GLFW commit ID__ (e.g. `3795d78b14ef06008889cc422a1fb8d642597751`) from Git. - -Please also include the __complete build log__ from your compiler and linker, -even if it's long. It can always be shortened later, if necessary. - - -#### Quick template - -``` -OS and version: -Compiler version: -Release or commit: -Build log: -``` - - -### Reporting a segfault or other crash bug - -Always include the __operating system name and version__ (e.g. `Windows -7 64-bit` or `Ubuntu 15.10`). If you are using an official release of GLFW, -include the __GLFW release version__ (e.g. `3.1.2`), otherwise include the -__GLFW commit ID__ (e.g. `3795d78b14ef06008889cc422a1fb8d642597751`) from Git. - -Please also include any __error messages__ provided to your application via the -[error -callback](http://www.glfw.org/docs/latest/intro_guide.html#error_handling) and -the __full call stack__ of the crash, or if the crash does not occur in debug -mode, mention that instead. - - -#### Quick template - -``` -OS and version: -Release or commit: -Error messages: -Call stack: -``` - - -### Reporting a context creation bug - -__Note:__ Windows ships with graphics drivers that do not support OpenGL. If -GLFW says that your machine lacks support for OpenGL, it very likely does. -Install drivers from the computer manufacturer or graphics card manufacturer -([Nvidia](http://www.geforce.com/drivers), -[AMD](http://support.amd.com/en-us/download), -[Intel](https://www-ssl.intel.com/content/www/us/en/support/detect.html)) to -fix this. - -__Note:__ AMD only supports OpenGL ES on Windows via EGL. See the -[GLFW\_CONTEXT\_CREATION\_API](http://www.glfw.org/docs/latest/window_guide.html#window_hints_ctx) -hint for how to select EGL. - -Please verify that context creation also fails with the `glfwinfo` tool before -reporting it as a bug. This tool is included in the GLFW source tree as -`tests/glfwinfo.c` and is built along with the library. It has switches for all -GLFW context and framebuffer hints. Run `glfwinfo -h` for a complete list. - -Always include the __operating system name and version__ (e.g. `Windows -7 64-bit` or `Ubuntu 15.10`). If you are using an official release of GLFW, -include the __GLFW release version__ (e.g. `3.1.2`), otherwise include the -__GLFW commit ID__ (e.g. `3795d78b14ef06008889cc422a1fb8d642597751`) from Git. - -If you are running your program in a virtual machine, please mention this and -include the __VM name and version__ (e.g. `VirtualBox 5.1`). - -Please also include the __GLFW version string__ (`3.2.0 X11 EGL clock_gettime -/dev/js`), as described -[here](http://www.glfw.org/docs/latest/intro.html#intro_version_string), the -__GPU model and driver version__ (e.g. `GeForce GTX660 with 352.79`), and the -__output of `glfwinfo`__ (with switches matching any hints you set in your -code) when reporting this kind of bug. If this tool doesn't run on the machine, -mention that instead. - - -#### Quick template - -``` -OS and version: -GPU and driver: -Release or commit: -Version string: -glfwinfo output: -``` - - -### Reporting a monitor or video mode bug - -__Note:__ On headless systems on some platforms, no monitors are reported. This -causes glfwGetPrimaryMonitor to return `NULL`, which not all applications are -prepared for. - -__Note:__ Some third-party tools report more video modes than are approved of -by the OS. For safety and compatibility, GLFW only reports video modes the OS -wants programs to use. This is not a bug. - -The `monitors` tool is included in the GLFW source tree as `tests/monitors.c` -and is built along with the library. It lists all information GLFW provides -about monitors it detects. - -Always include the __operating system name and version__ (e.g. `Windows -7 64-bit` or `Ubuntu 15.10`). If you are using an official release of GLFW, -include the __GLFW release version__ (e.g. `3.1.2`), otherwise include the -__GLFW commit ID__ (e.g. `3795d78b14ef06008889cc422a1fb8d642597751`) from Git. - -If you are running your program in a virtual machine, please mention this and -include the __VM name and version__ (e.g. `VirtualBox 5.1`). - -Please also include any __error messages__ provided to your application via the -[error -callback](http://www.glfw.org/docs/latest/intro_guide.html#error_handling) and -the __output of `monitors`__ when reporting this kind of bug.

This is not a bug. Set a [refresh -callback](http://www.glfw.org/docs/latest/window.html#window_refresh) if you -want to keep the window contents updated during a move or size operation. - -The `events` tool is included in the GLFW source tree as `tests/events.c` and is -built along with the library. It prints all information provided to every -callback supported by GLFW as events occur. Each event is listed with the time -and a unique number to make discussions about event logs easier. The tool has -command-line options for creating multiple windows and full screen windows. - -Always include the __operating system name and version__ (e.g. `Windows -7 64-bit` or `Ubuntu 15.10`).

Features can be -added and existing parts can sometimes be overloaded (in the general sense of -doing more things, not in the C++ sense), but code written to the API of one -minor release should both compile and run on subsequent minor releases. - diff --git a/src/lib/third_party/glfw/OLD/docs/Doxyfile.in b/src/lib/third_party/glfw/OLD/docs/Doxyfile.in deleted file mode 100644 index c2069c5c..00000000 --- a/src/lib/third_party/glfw/OLD/docs/Doxyfile.in +++ /dev/null @@ -1,1862 +0,0 @@ -# Doxyfile 1.8.3.1 - -# This file describes the settings to be used by the documentation system -# doxygen (www.doxygen.org) for a project. -# -# All text after a hash (#) is considered a comment and will be ignored. -# The format is: -# TAG = value [value, ...] -# For lists items can also be appended using: -# TAG += value [value, ...] -# Values that contain spaces should be placed between quotes (" "). - -#--------------------------------------------------------------------------- -# Project related configuration options -#--------------------------------------------------------------------------- - -# This tag specifies the encoding used for all characters in the config file -# that follow.

Without this macro, GLFW will expect the necessary configuration -macros to be defined on the command-line. - -The window creation API is used to create windows, handle input, monitors, gamma -ramps and clipboard. The options are: - - - @b _GLFW_COCOA to use the Cocoa frameworks - - @b _GLFW_WIN32 to use the Win32 API - - @b _GLFW_X11 to use the X Window System - - @b _GLFW_WAYLAND to use the Wayland API (experimental and incomplete) - - @b _GLFW_MIR to use the Mir API (experimental and incomplete) - - @b _GLFW_OSMESA to use the OSMesa API (headless and non-interactive) - -If you are building GLFW as a shared library / dynamic library / DLL then you -must also define @b _GLFW_BUILD_DLL. Otherwise, you must not define it. - -If you are linking the Vulkan loader statically into your application then you -must also define @b _GLFW_VULKAN_STATIC. Otherwise, GLFW will attempt to use the -external version. - -If you are using a custom name for the Vulkan, EGL, GLX, OSMesa, OpenGL, GLESv1 -or GLESv2 library, you can override the default names by defining those you need -of @b _GLFW_VULKAN_LIBRARY, @b _GLFW_EGL_LIBRARY, @b _GLFW_GLX_LIBRARY, @b -_GLFW_OSMESA_LIBRARY, @b _GLFW_OPENGL_LIBRARY, @b _GLFW_GLESV1_LIBRARY and @b -_GLFW_GLESV2_LIBRARY. Otherwise, GLFW will use the built-in default names. - -For the EGL context creation API, the following options are available: - - - @b _GLFW_USE_EGLPLATFORM_H to use `EGL/eglplatform.h` for native handle - definitions (fallback) - -@note None of the @ref build_macros may be defined during the compilation of -GLFW. If you define any of these in your build files, make sure they are not -applied to the GLFW sources. - -*/ diff --git a/src/lib/third_party/glfw/OLD/docs/context.dox b/src/lib/third_party/glfw/OLD/docs/context.dox deleted file mode 100644 index 5e1eb25c..00000000 --- a/src/lib/third_party/glfw/OLD/docs/context.dox +++ /dev/null @@ -1,346 +0,0 @@ -/*! - -@page context_guide Context guide - -@tableofcontents - -This guide introduces the OpenGL and OpenGL ES context related functions of -GLFW.

The name and number of this chapter unfortunately varies between -versions and APIs, but has at times been named _Shared Objects and Multiple -Contexts_. - -GLFW comes with a barebones object sharing example program called `sharing`. - - -@subsection context_offscreen Offscreen contexts - -GLFW doesn't support creating contexts without an associated window. However, -contexts with hidden windows can be created with the -[GLFW_VISIBLE](@ref GLFW_VISIBLE_hint) window hint. - -@code -glfwWindowHint(GLFW_VISIBLE, GLFW_FALSE); - -GLFWwindow* offscreen_context = glfwCreateWindow(640, 480, "", NULL, NULL); -@endcode - -The window never needs to be shown and its context can be used as a plain -offscreen context. Depending on the window manager, the size of a hidden -window's framebuffer may not be usable or modifiable, so framebuffer -objects are recommended for rendering with such contexts. - -You should still [process events](@ref events) as long as you have at least one -window, even if none of them are visible. - -@macos The first time a window is created the menu bar is created. This is not -desirable for example when writing a command-line only application. Menu bar -creation can be disabled with the @ref GLFW_COCOA_MENUBAR init hint. - - -@subsection context_less Windows without contexts - -You can disable context creation by setting the -[GLFW_CLIENT_API](@ref GLFW_CLIENT_API_hint) hint to `GLFW_NO_API`. Windows -without contexts must not be passed to @ref glfwMakeContextCurrent or @ref -glfwSwapBuffers. - - -@section context_current Current context - -Before you can make OpenGL or OpenGL ES calls, you need to have a current -context of the correct type. A context can only be current for a single thread -at a time, and a thread can only have a single context current at a time. - -When moving a context between threads, you must make it non-current on the old -thread before making it current on the new one. - -The context of a window is made current with @ref glfwMakeContextCurrent. - -@code -glfwMakeContextCurrent(window); -@endcode - -The window of the current context is returned by @ref glfwGetCurrentContext. - -@code -GLFWwindow* window = glfwGetCurrentContext(); -@endcode - -The following GLFW functions require a context to be current.

The extension above was created by the ARB, but there -are many different affixes, like `NV` for Nvidia and `AMD` for, well, AMD. Any -group may also use the generic `EXT` affix. Lists of extensions, together with -their specifications, can be found at the -[OpenGL Registry](http://www.opengl.org/registry/) and -[OpenGL ES Registry](https://www.khronos.org/registry/gles/). - - -@subsection context_glext_auto Loading extension with a loader library - -An extension loader library is the easiest and best way to access both OpenGL and -OpenGL ES extensions and modern versions of the core OpenGL or OpenGL ES APIs. -They will take care of all the details of declaring and loading everything you -need. One such library is [glad](https://github.com/Dav1dde/glad) and there are -several others. - -The following example will use glad but all extension loader libraries work -similarly. - -First you need to generate the source files using the glad Python script. This -example generates a loader for any version of OpenGL, which is the default for -both GLFW and glad, but loaders for OpenGL ES, as well as loaders for specific -API versions and extension sets can be generated. The generated files are -written to the `output` directory. - -@code{.sh} -python main.py --generator c --no-loader --out-path output -@endcode - -The `--no-loader` option is added because GLFW already provides a function for -loading OpenGL and OpenGL ES function pointers, one that automatically uses the -selected context creation API, and glad can call this instead of having to -implement its own. There are several other command-line options as well. See -the glad documentation for details. - -Add the generated `output/src/glad.c`, `output/include/glad/glad.h` and -`output/include/KHR/khrplatform.h` files to your build. Then you need to -include the glad header file, which will replace the OpenGL header of your -development environment. By including the glad header before the GLFW header, -it suppresses the development environment's OpenGL or OpenGL ES header. - -@code -#include -#include -@endcode - -Finally you need to initialize glad once you have a suitable current context. - -@code -window = glfwCreateWindow(640, 480, "My Window", NULL, NULL); -if (!window) -{ - ... -} - -glfwMakeContextCurrent(window); - -gladLoadGLLoader((GLADloadproc) glfwGetProcAddress); -@endcode - -Once glad has been loaded, you have access to all OpenGL core and extension -functions supported by both the context you created and the glad loader you -generated and you are ready to start rendering. - -You can specify a minimum required OpenGL or OpenGL ES version with -[context hints](@ref window_hints_ctx). If your needs are more complex, you can -check the actual OpenGL or OpenGL ES version with -[context attributes](@ref window_attribs_ctx), or you can check whether -a specific version is supported by the current context with the -`GLAD_GL_VERSION_x_x` booleans. - -@code -if (GLAD_GL_VERSION_3_2) -{ - // Call OpenGL 3.2+ specific code -} -@endcode - -To check whether a specific extension is supported, use the `GLAD_GL_xxx` -booleans. - -@code -if (GLAD_GL_ARB_debug_output) -{ - // Use GL_ARB_debug_output -} -@endcode - - -@subsection context_glext_manual Loading extensions manually - -__Do not use this technique__ unless it is absolutely necessary. An -[extension loader library](@ref context_glext_auto) will save you a ton of -tedious, repetitive, error prone work. - -To use a certain extension, you must first check whether the context supports -that extension and then, if it introduces new functions, retrieve the pointers -to those functions. GLFW provides @ref glfwExtensionSupported and @ref -glfwGetProcAddress for manual loading of extensions and new API functions. - -This section will demonstrate manual loading of OpenGL extensions. The loading -of OpenGL ES extensions is identical except for the name of the extension header. - - -@subsubsection context_glext_header The glext.h header - -The `glext.h` extension header is a continually updated file that defines the -interfaces for all OpenGL extensions. The latest version of this can always be -found at the [OpenGL Registry](http://www.opengl.org/registry/). There are also -extension headers for the various versions of OpenGL ES at the -[OpenGL ES Registry](https://www.khronos.org/registry/gles/). It it strongly -recommended that you use your own copy of the extension header, as the one -included in your development environment may be several years out of date and -may not include the extensions you wish to use. - -The header defines function pointer types for all functions of all extensions it -supports. These have names like `PFNGLGETDEBUGMESSAGELOGARBPROC` (for -`glGetDebugMessageLogARB`), i.e. the name is made uppercase and `PFN` (pointer -to function) and `PROC` (procedure) are added to the ends. - -To include the extension header, define @ref GLFW_INCLUDE_GLEXT before including -the GLFW header. - -@code -#define GLFW_INCLUDE_GLEXT -#include -@endcode - - -@subsubsection context_glext_string Checking for extensions - -A given machine may not actually support the extension (it may have older -drivers or a graphics card that lacks the necessary hardware features), so it -is necessary to check at run-time whether the context supports the extension. -This is done with @ref glfwExtensionSupported. - -@code -if (glfwExtensionSupported("GL_ARB_debug_output")) -{ - // The extension is supported by the current context -} -@endcode - -The argument is a null terminated ASCII string with the extension name. If the -extension is supported, @ref glfwExtensionSupported returns `GLFW_TRUE`, -otherwise it returns `GLFW_FALSE`. - - -@subsubsection context_glext_proc Fetching function pointers - -Many extensions, though not all, require the use of new OpenGL functions. -These functions often do not have entry points in the client API libraries of -your operating system, making it necessary to fetch them at run time. You can -retrieve pointers to these functions with @ref glfwGetProcAddress. - -@code -PFNGLGETDEBUGMESSAGELOGARBPROC pfnGetDebugMessageLog = glfwGetProcAddress("glGetDebugMessageLogARB"); -@endcode - -In general, you should avoid giving the function pointer variables the (exact) -same name as the function, as this may confuse your linker. Instead, you can -use a different prefix, like above, or some other naming scheme. - -Now that all the pieces have been introduced, here is what they might look like -when used together. - -@code -#define GLFW_INCLUDE_GLEXT -#include - -#define glGetDebugMessageLogARB pfnGetDebugMessageLog -PFNGLGETDEBUGMESSAGELOGARBPROC pfnGetDebugMessageLog; - -// Flag indicating whether the extension is supported -int has_ARB_debug_output = 0; - -void load_extensions(void) -{ - if (glfwExtensionSupported("GL_ARB_debug_output")) - { - pfnGetDebugMessageLog = (PFNGLGETDEBUGMESSAGELOGARBPROC) - glfwGetProcAddress("glGetDebugMessageLogARB"); - has_ARB_debug_output = 1; - } -} - -void some_function(void) -{ - if (has_ARB_debug_output) - { - // Now the extension function can be called as usual

For details on -a specific function in this category, see the @ref input. There are also guides -for the other areas of GLFW. - - - @ref intro_guide - - @ref window_guide - - @ref context_guide - - @ref vulkan_guide - - @ref monitor_guide - -GLFW provides many kinds of input. While some can only be polled, like time, or -only received via callbacks, like scrolling, many provide both callbacks and -polling. Callbacks are more work to use than polling but is less CPU intensive -and guarantees that you do not miss state changes. - -All input callbacks receive a window handle. By using the -[window user pointer](@ref window_userptr), you can access non-global structures -or objects from your callbacks. - -To get a better feel for how the various events callbacks behave, run the -`events` test program. It register every callback supported by GLFW and prints -out all arguments provided for every event, along with time and sequence -information. - - -@section events Event processing - -GLFW needs to poll the window system for events both to provide input to the -application and to prove to the window system that the application hasn't locked -up. Event processing is normally done each frame after -[buffer swapping](@ref buffer_swap). Even when you have no windows, event -polling needs to be done in order to receive monitor and joystick connection -events. - -There are three functions for processing pending events. @ref glfwPollEvents, -processes only those events that have already been received and then returns -immediately. - -@code -glfwPollEvents(); -@endcode - -This is the best choice when rendering continuously, like most games do. - -If you only need to update the contents of the window when you receive new -input, @ref glfwWaitEvents is a better choice. - -@code -glfwWaitEvents(); -@endcode - -It puts the thread to sleep until at least one event has been received and then -processes all received events. This saves a great deal of CPU cycles and is -useful for, for example, editing tools. There must be at least one GLFW window -for this function to sleep. - -If you want to wait for events but have UI elements or other tasks that need -periodic updates, @ref glfwWaitEventsTimeout lets you specify a timeout. - -@code -glfwWaitEventsTimeout(0.7); -@endcode - -It puts the thread to sleep until at least one event has been received, or until -the specified number of seconds have elapsed. It then processes any received -events. - -If the main thread is sleeping in @ref glfwWaitEvents, you can wake it from -another thread by posting an empty event to the event queue with @ref -glfwPostEmptyEvent. - -@code -glfwPostEmptyEvent(); -@endcode - -Do not assume that callbacks will _only_ be called in response to the above -functions. While it is necessary to process events in one or more of the ways -above, window systems that require GLFW to register callbacks of its own can -pass events to GLFW in response to many window system function calls. GLFW will -pass those events on to the application callbacks before returning. - -For example, on Windows the system function that @ref glfwSetWindowSize is -implemented with will send window size events directly to the event callback -that every window has and that GLFW implements for its windows. If you have set -a [window size callback](@ref window_size) GLFW will call it in turn with the -new size before everything returns back out of the @ref glfwSetWindowSize call. - - -@section input_keyboard Keyboard input - -GLFW divides keyboard input into two categories; key events and character -events. Key events relate to actual physical keyboard keys, whereas character -events relate to the Unicode code points generated by pressing some of them. - -Keys and characters do not map 1:1. A single key press may produce several -characters, and a single character may require several keys to produce. This -may not be the case on your machine, but your users are likely not all using the -same keyboard layout, input method or even operating system as you. - - -@subsection input_key Key input - -If you wish to be notified when a physical key is pressed or released or when it -repeats, set a key callback. - -@code -glfwSetKeyCallback(window, key_callback); -@endcode - -The callback function receives the [keyboard key](@ref keys), platform-specific -scancode, key action and [modifier bits](@ref mods). - -@code -void key_callback(GLFWwindow* window, int key, int scancode, int action, int mods) -{ - if (key == GLFW_KEY_E && action == GLFW_PRESS) - activate_airship(); -} -@endcode - -The action is one of `GLFW_PRESS`, `GLFW_REPEAT` or `GLFW_RELEASE`. The key -will be `GLFW_KEY_UNKNOWN` if GLFW lacks a key token for it, for example -_E-mail_ and _Play_ keys. - -The scancode is unique for every key, regardless of whether it has a key token. -Scancodes are platform-specific but consistent over time, so keys will have -different scancodes depending on the platform but they are safe to save to disk. -You can query the scancode for any [named key](@ref keys) on the current -platform with @ref glfwGetKeyScancode. - -@code -const int scancode = glfwGetKeyScancode(GLFW_KEY_X); -set_key_mapping(scancode, swap_weapons); -@endcode - -The last reported state for every [named key](@ref keys) is also saved in -per-window state arrays that can be polled with @ref glfwGetKey. - -@code -int state = glfwGetKey(window, GLFW_KEY_E); -if (state == GLFW_PRESS) -{ - activate_airship(); -} -@endcode - -The returned state is one of `GLFW_PRESS` or `GLFW_RELEASE`. - -This function only returns cached key event state. It does not poll the -system for the current physical state of the key. - -@anchor GLFW_STICKY_KEYS -Whenever you poll state, you risk missing the state change you are looking for. -If a pressed key is released again before you poll its state, you will have -missed the key press. The recommended solution for this is to use a -key callback, but there is also the `GLFW_STICKY_KEYS` input mode. - -@code -glfwSetInputMode(window, GLFW_STICKY_KEYS, 1); -@endcode - -When sticky keys mode is enabled, the pollable state of a key will remain -`GLFW_PRESS` until the state of that key is polled with @ref glfwGetKey. Once -it has been polled, if a key release event had been processed in the meantime, -the state will reset to `GLFW_RELEASE`, otherwise it will remain `GLFW_PRESS`. - -@anchor GLFW_LOCK_KEY_MODS -If you wish to know what the state of the Caps Lock and Num Lock keys was when -input events were generated, set the `GLFW_LOCK_KEY_MODS` input mode. - -@code -glfwSetInputMode(window, GLFW_LOCK_KEY_MODS, 1); -@endcode - -When this input mode is enabled, any callback that receives -[modifier bits](@ref mods) will have the @ref GLFW_MOD_CAPS_LOCK bit set if Caps -Lock was on when the event occurred and the @ref GLFW_MOD_NUM_LOCK bit set if -Num Lock was on. - -The `GLFW_KEY_LAST` constant holds the highest value of any -[named key](@ref keys). - - -@subsection input_char Text input - -GLFW supports text input in the form of a stream of -[Unicode code points](https://en.wikipedia.org/wiki/Unicode), as produced by the -operating system text input system. Unlike key input, text input obeys keyboard -layouts and modifier keys and supports composing characters using -[dead keys](https://en.wikipedia.org/wiki/Dead_key). Once received, you can -encode the code points into UTF-8 or any other encoding you prefer. - -Because an `unsigned int` is 32 bits long on all platforms supported by GLFW, -you can treat the code point argument as native endian UTF-32. - -If you wish to offer regular text input, set a character callback. - -@code -glfwSetCharCallback(window, character_callback); -@endcode - -The callback function receives Unicode code points for key events that would -have led to regular text input and generally behaves as a standard text field on -that platform. - -@code -void character_callback(GLFWwindow* window, unsigned int codepoint) -{ -} -@endcode - - -@subsection input_key_name Key names - -If you wish to refer to keys by name, you can query the keyboard layout -dependent name of printable keys with @ref glfwGetKeyName. - -@code -const char* key_name = glfwGetKeyName(GLFW_KEY_W, 0); -show_tutorial_hint("Press %s to move forward", key_name); -@endcode - -This function can handle both [keys and scancodes](@ref input_key). If the -specified key is `GLFW_KEY_UNKNOWN` then the scancode is used, otherwise it is -ignored. This matches the behavior of the key callback, meaning the callback -arguments can always be passed unmodified to this function. - - -@section input_mouse Mouse input - -Mouse input comes in many forms, including cursor motion, button presses and -scrolling offsets. The cursor appearance can also be changed, either to -a custom image or a standard cursor shape from the system theme. - - -@subsection cursor_pos Cursor position - -If you wish to be notified when the cursor moves over the window, set a cursor -position callback. - -@code -glfwSetCursorPosCallback(window, cursor_pos_callback); -@endcode - -The callback functions receives the cursor position, measured in screen -coordinates but relative to the top-left corner of the window client area. On -platforms that provide it, the full sub-pixel cursor position is passed on. - -@code -static void cursor_position_callback(GLFWwindow* window, double xpos, double ypos) -{ -} -@endcode - -The cursor position is also saved per-window and can be polled with @ref -glfwGetCursorPos. - -@code -double xpos, ypos; -glfwGetCursorPos(window, &xpos, &ypos); -@endcode - - -@subsection cursor_mode Cursor mode - -@anchor GLFW_CURSOR -The `GLFW_CURSOR` input mode provides several cursor modes for special forms of -mouse motion input. By default, the cursor mode is `GLFW_CURSOR_NORMAL`, -meaning the regular arrow cursor (or another cursor set with @ref glfwSetCursor) -is used and cursor motion is not limited. - -If you wish to implement mouse motion based camera controls or other input -schemes that require unlimited mouse movement, set the cursor mode to -`GLFW_CURSOR_DISABLED`. - -@code -glfwSetInputMode(window, GLFW_CURSOR, GLFW_CURSOR_DISABLED); -@endcode - -This will hide the cursor and lock it to the specified window. GLFW will then -take care of all the details of cursor re-centering and offset calculation and -providing the application with a virtual cursor position. This virtual position -is provided normally via both the cursor position callback and through polling. - -@note You should not implement your own version of this functionality using -other features of GLFW. It is not supported and will not work as robustly as -`GLFW_CURSOR_DISABLED`. - -If you only wish the cursor to become hidden when it is over a window but still -want it to behave normally, set the cursor mode to `GLFW_CURSOR_HIDDEN`. - -@code -glfwSetInputMode(window, GLFW_CURSOR, GLFW_CURSOR_HIDDEN); -@endcode - -This mode puts no limit on the motion of the cursor. - -To exit out of either of these special modes, restore the `GLFW_CURSOR_NORMAL` -cursor mode. - -@code -glfwSetInputMode(window, GLFW_CURSOR, GLFW_CURSOR_NORMAL); -@endcode - - -@subsection cursor_object Cursor objects - -GLFW supports creating both custom and system theme cursor images, encapsulated -as @ref GLFWcursor objects. They are created with @ref glfwCreateCursor or @ref -glfwCreateStandardCursor and destroyed with @ref glfwDestroyCursor, or @ref -glfwTerminate, if any remain. - - -@subsubsection cursor_custom Custom cursor creation - -A custom cursor is created with @ref glfwCreateCursor, which returns a handle to -the created cursor object. For example, this creates a 16x16 white square -cursor with the hot-spot in the upper-left corner: - -@code -unsigned char pixels[16 * 16 * 4]; -memset(pixels, 0xff, sizeof(pixels)); - -GLFWimage image; -image.width = 16; -image.height = 16; -image.pixels = pixels; - -GLFWcursor* cursor = glfwCreateCursor(&image, 0, 0); -@endcode - -If cursor creation fails, `NULL` will be returned, so it is necessary to check -the return value. - -The image data is 32-bit, little-endian, non-premultiplied RGBA, i.e. eight bits -per channel with the red channel first. The pixels are arranged canonically as -sequential rows, starting from the top-left corner. - - -@subsubsection cursor_standard Standard cursor creation - -A cursor with a [standard shape](@ref shapes) from the current system cursor -theme can be can be created with @ref glfwCreateStandardCursor. - -@code -GLFWcursor* cursor = glfwCreateStandardCursor(GLFW_HRESIZE_CURSOR); -@endcode - -These cursor objects behave in the exact same way as those created with @ref -glfwCreateCursor except that the system cursor theme provides the actual image. - - -@subsubsection cursor_destruction Cursor destruction - -When a cursor is no longer needed, destroy it with @ref glfwDestroyCursor. - -@code -glfwDestroyCursor(cursor); -@endcode - -Cursor destruction always succeeds. If the cursor is current for any window, -that window will revert to the default cursor. This does not affect the cursor -mode. All remaining cursors remaining are destroyed when @ref glfwTerminate is -called. - - -@subsubsection cursor_set Cursor setting - -A cursor can be set as current for a window with @ref glfwSetCursor. - -@code -glfwSetCursor(window, cursor); -@endcode - -Once set, the cursor image will be used as long as the system cursor is over the -client area of the window and the [cursor mode](@ref cursor_mode) is set -to `GLFW_CURSOR_NORMAL`. - -A single cursor may be set for any number of windows. - -To revert to the default cursor, set the cursor of that window to `NULL`. - -@code -glfwSetCursor(window, NULL); -@endcode - -When a cursor is destroyed, any window that has it set will revert to the -default cursor. This does not affect the cursor mode. - - -@subsection cursor_enter Cursor enter/leave events - -If you wish to be notified when the cursor enters or leaves the client area of -a window, set a cursor enter/leave callback. - -@code -glfwSetCursorEnterCallback(window, cursor_enter_callback); -@endcode - -The callback function receives the new classification of the cursor. - -@code -void cursor_enter_callback(GLFWwindow* window, int entered) -{ - if (entered) - { - // The cursor entered the client area of the window - } - else - { - // The cursor left the client area of the window - } -} -@endcode - -You can query whether the cursor is currently inside the client area of the -window with the [GLFW_HOVERED](@ref GLFW_HOVERED_attrib) window attribute. - -@code -if (glfwGetWindowAttrib(window, GLFW_HOVERED)) -{ - highlight_interface(); -} -@endcode - - -@subsection input_mouse_button Mouse button input - -If you wish to be notified when a mouse button is pressed or released, set -a mouse button callback. - -@code -glfwSetMouseButtonCallback(window, mouse_button_callback); -@endcode - -The callback function receives the [mouse button](@ref buttons), button action -and [modifier bits](@ref mods). - -@code -void mouse_button_callback(GLFWwindow* window, int button, int action, int mods) -{ - if (button == GLFW_MOUSE_BUTTON_RIGHT && action == GLFW_PRESS) - popup_menu(); -} -@endcode - -The action is one of `GLFW_PRESS` or `GLFW_RELEASE`. - -Mouse button states for [named buttons](@ref buttons) are also saved in -per-window state arrays that can be polled with @ref glfwGetMouseButton. - -@code -int state = glfwGetMouseButton(window, GLFW_MOUSE_BUTTON_LEFT); -if (state == GLFW_PRESS) -{ - upgrade_cow(); -} -@endcode - -The returned state is one of `GLFW_PRESS` or `GLFW_RELEASE`. - -This function only returns cached mouse button event state.

Once it has been polled, if a mouse button release event -had been processed in the meantime, the state will reset to `GLFW_RELEASE`, -otherwise it will remain `GLFW_PRESS`. - -The `GLFW_MOUSE_BUTTON_LAST` constant holds the highest value of any -[named button](@ref buttons). - - -@subsection scrolling Scroll input - -If you wish to be notified when the user scrolls, whether with a mouse wheel or -touchpad gesture, set a scroll callback. - -@code -glfwSetScrollCallback(window, scroll_callback); -@endcode - -The callback function receives two-dimensional scroll offsets. - -@code -void scroll_callback(GLFWwindow* window, double xoffset, double yoffset) -{ -} -@endcode - -A normal mouse wheel, being vertical, provides offsets along the Y-axis. - - -@section joystick Joystick input - -The joystick functions expose connected joysticks and controllers, with both -referred to as joysticks. It supports up to sixteen joysticks, ranging from -`GLFW_JOYSTICK_1`, `GLFW_JOYSTICK_2` up to and including `GLFW_JOYSTICK_16` or -`GLFW_JOYSTICK_LAST`. You can test whether a [joystick](@ref joysticks) is -present with @ref glfwJoystickPresent. - -@code -int present = glfwJoystickPresent(GLFW_JOYSTICK_1); -@endcode - -Each joystick has zero or more axes, zero or more buttons, zero or more hats, -a human-readable name, a user pointer and an SDL compatible GUID. - -When GLFW is initialized, detected joysticks are added to to the beginning of -the array. Once a joystick is detected, it keeps its assigned ID until it is -disconnected or the library is terminated, so as joysticks are connected and -disconnected, there may appear gaps in the IDs. - -Joystick axis, button and hat state is updated when polled and does not require -a window to be created or events to be processed. However, if you want joystick -connection and disconnection events reliably delivered to the -[joystick callback](@ref joystick_event) then you must -[process events](@ref events). - -To see all the properties of all connected joysticks in real-time, run the -`joysticks` test program. - - -@subsection joystick_axis Joystick axis states - -The positions of all axes of a joystick are returned by @ref -glfwGetJoystickAxes.

Joystick buttons are specified as `bN`, for example -`b2` for the third button. Joystick axes are specified as `aN`, for example -`a7` for the eighth button. Joystick hat bit masks are specified as `hN.N`, for -example `h0.8` for left on the first hat. More than one bit may be set in the -mask. - -Before an axis there may be a `+` or `-` range modifier, for example `+a3` for -the positive half of the fourth axis.

Both use the same unit: _virtual screen -coordinates_, or just _screen coordinates_, which don't necessarily correspond -to pixels. - - - -Both the virtual screen and the client area coordinate systems have the X-axis -pointing to the right and the Y-axis pointing down. - -Window and monitor positions are specified as the position of the upper-left -corners of their content areas relative to the virtual screen, while cursor -positions are specified relative to a window's client area. - -Because the origin of the window's client area coordinate system is also the -point from which the window position is specified, you can translate client area -coordinates to the virtual screen by adding the window position. The window -frame, when present, extends out from the client area but does not affect the -window position. - -Almost all positions and sizes in GLFW are measured in screen coordinates -relative to one of the two origins above. This includes cursor positions, -window positions and sizes, window frame sizes, monitor positions and video mode -resolutions. - -Two exceptions are the [monitor physical size](@ref monitor_size), which is -measured in millimetres, and [framebuffer size](@ref window_fbsize), which is -measured in pixels. - -Pixels and screen coordinates may map 1:1 on your machine, but they won't on -every other machine, for example on a Mac with a Retina display. The ratio -between screen coordinates and pixels may also change at run-time depending on -which monitor the window is currently considered to be on. - - -@section guarantees_limitations Guarantees and limitations - -This section describes the conditions under which GLFW can be expected to -function, barring bugs in the operating system or drivers. Use of GLFW outside -of these limits may work on some platforms, or on some machines, or some of the -time, or on some versions of GLFW, but it may break at any time and this will -not be considered a bug. - - -@subsection lifetime Pointer lifetimes - -GLFW will never free any pointer you provide to it and you must never free any -pointer it provides to you. - -Many GLFW functions return pointers to dynamically allocated structures, strings -or arrays, and some callbacks are provided with strings or arrays. These are -always managed by GLFW and should never be freed by the application. The -lifetime of these pointers is documented for each GLFW function and callback. -If you need to keep this data, you must copy it before its lifetime expires. - -Many GLFW functions accept pointers to structures or strings allocated by the -application. These are never freed by GLFW and are always the responsibility of -the application. If GLFW needs to keep the data in these structures or strings, -it is copied before the function returns. - -Pointer lifetimes are guaranteed not to be shortened in future minor or patch -releases. - - -@subsection reentrancy Reentrancy - -GLFW event processing and object destruction are not reentrant.

This guarantees source -and binary backward compatibility with earlier minor versions of the API. This -means that you can drop in a newer version of the library and existing programs -will continue to compile and existing binaries will continue to run. - -Once a function or constant has been added, the signature of that function or -value of that constant will remain unchanged until the next major version of -GLFW. No compatibility of any kind is guaranteed between major versions. - -Undocumented behavior, i.e. behavior that is not described in the documentation, -may change at any time until it is documented. - -If the reference documentation and the implementation differ, the reference -documentation will almost always take precedence and the implementation will be -fixed in the next release.

The MSDN library doesn't even provide -documentation for version older than Windows 2000, making it difficult to -maintain compatibility with these versions even if it was deemed worth the -effort. - -The Win32 API has also not stood still, and GLFW 3 uses many functions only -present on Windows XP or later. Even supporting an OS as new as XP (new -from the perspective of GLFW 2, which still supports Windows 95) requires -runtime checking for a number of functions that are present only on modern -version of Windows. - - -@subsection moving_syskeys Capture of system-wide hotkeys - -The ability to disable and capture system-wide hotkeys like Alt+Tab has been -removed. Modern applications, whether they're games, scientific visualisations -or something else, are nowadays expected to be good desktop citizens and allow -these hotkeys to function even when running in full screen mode. - - -@subsection moving_terminate Automatic termination - -GLFW 3 does not register @ref glfwTerminate with `atexit` at initialization, -because `exit` calls registered functions from the calling thread and while it -is permitted to call `exit` from any thread, @ref glfwTerminate must only be -called from the main thread. - -To release all resources allocated by GLFW, you should call @ref glfwTerminate -yourself, from the main thread, before the program terminates.

Some of them use GLFW to create the context and window -while others use GLUT or SDL, but remember that OpenGL itself always works the -same. - - -@subsection quick_timer Reading the timer - -To create smooth animation, a time source is needed. GLFW provides a timer that -returns the number of seconds since initialization. The time source used is the -most accurate on each platform and generally has micro- or nanosecond -resolution. - -@code -double time = glfwGetTime(); -@endcode - - -@subsection quick_swap_buffers Swapping buffers - -GLFW windows by default use double buffering. That means that each window has -two rendering buffers; a front buffer and a back buffer. The front buffer is -the one being displayed and the back buffer the one you render to. - -When the entire frame has been rendered, the buffers need to be swapped with one -another, so the back buffer becomes the front buffer and vice versa. - -@code -glfwSwapBuffers(window); -@endcode - -The swap interval indicates how many frames to wait until swapping the buffers, -commonly known as _vsync_. By default, the swap interval is zero, meaning -buffer swapping will occur immediately. On fast machines, many of those frames -will never be seen, as the screen is still only updated typically 60-75 times -per second, so this wastes a lot of CPU and GPU cycles. - -Also, because the buffers will be swapped in the middle the screen update, -leading to [screen tearing](https://en.wikipedia.org/wiki/Screen_tearing). - -For these reasons, applications will typically want to set the swap interval to -one. It can be set to higher values, but this is usually not recommended, -because of the input latency it leads to. - -@code -glfwSwapInterval(1); -@endcode - -This function acts on the current context and will fail unless a context is -current. - - -@subsection quick_process_events Processing events - -GLFW needs to communicate regularly with the window system both in order to -receive events and to show that the application hasn't locked up. Event -processing must be done regularly while you have visible windows and is normally -done each frame after buffer swapping. - -There are two methods for processing pending events; polling and waiting. This -example will use event polling, which processes only those events that have -already been received and then returns immediately. - -@code -glfwPollEvents(); -@endcode - -This is the best choice when rendering continually, like most games do. If -instead you only need to update your rendering once you have received new input, -@ref glfwWaitEvents is a better choice. It waits until at least one event has -been received, putting the thread to sleep in the meantime, and then processes -all received events. This saves a great deal of CPU cycles and is useful for, -for example, many kinds of editing tools. - - -@section quick_example Putting it together - -Now that you know how to initialize GLFW, create a window and poll for -keyboard input, it's possible to create a simple program. - -This program creates a 640 by 480 windowed mode window and starts a loop that -clears the screen, renders a triangle and processes events until the user either -presses _Escape_ or closes the window. - -@snippet simple.c code - -The program above can be found in the -[source package](http://www.glfw.org/download.html) as `examples/simple.c` -and is compiled along with all other examples when you build GLFW. If you -built GLFW from the source package then already have this as `simple.exe` on -Windows, `simple` on Linux or `simple.app` on macOS. - -This tutorial used only a few of the many functions GLFW provides. There are -guides for each of the areas covered by GLFW. Each guide will introduce all the -functions for that category. - - - @ref intro_guide - - @ref window_guide - - @ref context_guide - - @ref monitor_guide - - @ref input_guide - -You can access reference documentation for any GLFW function by clicking it and -the reference for each function links to related functions and guide sections. - -The tutorial ends here. Once you have written a program that uses GLFW, you -will need to compile and link it. How to do that depends on the development -environment you are using and is best explained by the documentation for that -environment.

That means that you have two -rendering buffers; a front buffer and a back buffer. The front buffer is -the one being displayed and the back buffer the one you render to. - -When the entire frame has been rendered, it is time to swap the back and the -front buffers in order to display what has been rendered and begin rendering -a new frame. This is done with @ref glfwSwapBuffers. - -@code -glfwSwapBuffers(window); -@endcode - -Sometimes it can be useful to select when the buffer swap will occur. With the -function @ref glfwSwapInterval it is possible to select the minimum number of -monitor refreshes the driver wait should from the time @ref glfwSwapBuffers was -called before swapping the buffers: - -@code -glfwSwapInterval(1); -@endcode - -If the interval is zero, the swap will take place immediately when @ref -glfwSwapBuffers is called without waiting for a refresh. Otherwise at least -interval retraces will pass between each buffer swap. Using a swap interval of -zero can be useful for benchmarking purposes, when it is not desirable to -measure the time it takes to wait for the vertical retrace. However, a swap -interval of one lets you avoid tearing. - -Note that this may not work on all machines, as some drivers have -user-controlled settings that override any swap interval the application -requests. - -A context that supports either the `WGL_EXT_swap_control_tear` or the -`GLX_EXT_swap_control_tear` extension also accepts _negative_ swap intervals, -which allows the driver to swap immediately even if a frame arrives a little bit -late. This trades the risk of visible tears for greater framerate stability. -You can check for these extensions with @ref glfwExtensionSupported. - -*/ diff --git a/src/lib/third_party/glfw/OLD/examples/CMakeLists.txt b/src/lib/third_party/glfw/OLD/examples/CMakeLists.txt deleted file mode 100644 index b458609f..00000000 --- a/src/lib/third_party/glfw/OLD/examples/CMakeLists.txt +++ /dev/null @@ -1,77 +0,0 @@ - -link_libraries(glfw) - -include_directories(${glfw_INCLUDE_DIRS} "${GLFW_SOURCE_DIR}/deps") - -if (MATH_LIBRARY) - link_libraries("${MATH_LIBRARY}") -endif() - -if (MSVC) - add_definitions(-D_CRT_SECURE_NO_WARNINGS) -endif() - -if (GLFW_USE_OSMESA) - add_definitions(-DUSE_NATIVE_OSMESA) -endif() - -if (WIN32) - set(ICON glfw.rc) -elseif (APPLE) - set(ICON glfw.icns) - set_source_files_properties(glfw.icns PROPERTIES - MACOSX_PACKAGE_LOCATION "Resources") -endif() - -set(GLAD "${GLFW_SOURCE_DIR}/deps/glad/glad.h" - "${GLFW_SOURCE_DIR}/deps/glad.c") -set(GETOPT "${GLFW_SOURCE_DIR}/deps/getopt.h" - "${GLFW_SOURCE_DIR}/deps/getopt.c") -set(TINYCTHREAD "${GLFW_SOURCE_DIR}/deps/tinycthread.h" - "${GLFW_SOURCE_DIR}/deps/tinycthread.c") - -add_executable(boing WIN32 MACOSX_BUNDLE boing.c ${ICON} ${GLAD}) -add_executable(gears WIN32 MACOSX_BUNDLE gears.c ${ICON} ${GLAD}) -add_executable(heightmap WIN32 MACOSX_BUNDLE heightmap.c ${ICON} ${GLAD}) -add_executable(offscreen offscreen.c ${ICON} ${GLAD}) -add_executable(particles WIN32 MACOSX_BUNDLE particles.c ${ICON} ${TINYCTHREAD} ${GETOPT} ${GLAD}) -add_executable(sharing WIN32 MACOSX_BUNDLE sharing.c ${ICON} ${GLAD}) -add_executable(simple WIN32 MACOSX_BUNDLE simple.c ${ICON} ${GLAD}) -add_executable(splitview WIN32 MACOSX_BUNDLE splitview.c ${ICON} ${GLAD}) -add_executable(wave WIN32 MACOSX_BUNDLE wave.c ${ICON} ${GLAD}) - -target_link_libraries(particles "${CMAKE_THREAD_LIBS_INIT}") -if (RT_LIBRARY) - target_link_libraries(particles "${RT_LIBRARY}") -endif() - -set(WINDOWS_BINARIES boing gears heightmap particles sharing simple splitview wave) -set(CONSOLE_BINARIES offscreen) - -set_target_properties(${WINDOWS_BINARIES} ${CONSOLE_BINARIES} PROPERTIES - FOLDER "GLFW3/Examples") - -if (MSVC) - # Tell MSVC to use main instead of WinMain for Windows subsystem executables - set_target_properties(${WINDOWS_BINARIES} PROPERTIES - LINK_FLAGS "/ENTRY:mainCRTStartup") -endif() - -if (APPLE) - set_target_properties(boing PROPERTIES MACOSX_BUNDLE_BUNDLE_NAME "Boing") - set_target_properties(gears PROPERTIES MACOSX_BUNDLE_BUNDLE_NAME "Gears") - set_target_properties(heightmap PROPERTIES MACOSX_BUNDLE_BUNDLE_NAME "Heightmap") - set_target_properties(particles PROPERTIES MACOSX_BUNDLE_BUNDLE_NAME "Particles") - set_target_properties(sharing PROPERTIES MACOSX_BUNDLE_BUNDLE_NAME "Sharing") - set_target_properties(simple PROPERTIES MACOSX_BUNDLE_BUNDLE_NAME "Simple") - set_target_properties(splitview PROPERTIES MACOSX_BUNDLE_BUNDLE_NAME "SplitView") - set_target_properties(wave PROPERTIES MACOSX_BUNDLE_BUNDLE_NAME "Wave") - - set_target_properties(${WINDOWS_BINARIES} PROPERTIES - RESOURCE glfw.icns - MACOSX_BUNDLE_SHORT_VERSION_STRING ${GLFW_VERSION} - MACOSX_BUNDLE_LONG_VERSION_STRING ${GLFW_VERSION_FULL} - MACOSX_BUNDLE_ICON_FILE glfw.icns - MACOSX_BUNDLE_INFO_PLIST "${GLFW_SOURCE_DIR}/CMake/MacOSXBundleInfo.plist.in") -endif() - diff --git a/src/lib/third_party/glfw/OLD/examples/boing.c b/src/lib/third_party/glfw/OLD/examples/boing.c deleted file mode 100644 index 45c867fd..00000000 --- a/src/lib/third_party/glfw/OLD/examples/boing.c +++ /dev/null @@ -1,678 +0,0 @@ -/***************************************************************************** - * Title: GLBoing - * Desc: Tribute to Amiga Boing. - * Author: Jim Brooks - * Original Amiga authors were R.J.
