UiBuilder troubles

[matytyma]

Whenever I try to use an UiBuilder instance in order to create a window (I have even tried copying the UiBuilder demo code (including the ui file) and did not succeed...), the program just finishes without displaying any window. This is my code at the moment:

import ch.bailu.gtk.gio.ApplicationFlags
import ch.bailu.gtk.gtk.Application
import ch.bailu.gtk.gtk.Window
import ch.bailu.gtk.lib.bridge.UiBuilder
import ch.bailu.gtk.type.Strs
import kotlin.system.exitProcess

fun main(args: Array<String>) {
    val app = Application("dev.matytyma.DevTools", ApplicationFlags.FLAGS_NONE)
    app.onActivate {
        val builder = UiBuilder.fromResource("/window.ui")
        val window = Window(builder.getObject("window"))
        window.show()
    }
    exitProcess(app.run(args.size, Strs(args)));
}

A GTK application needs an application Window. It's a GTK Api thing.
I'm not exactly sure what the correct way is to set an application window in this case but I've managed to run your example by adding app.addWindow(window)

fun main(args: Array<String>) {
    val app = Application("dev.matytyma.DevTools", ApplicationFlags.FLAGS_NONE)
    app.onActivate {
        val builder = UiBuilder.fromResource("/window.ui")
        val window = Window(builder.getObject("window"))
        app.addWindow(window)
        window.show()
    }
   exitProcess(app.run(args.size, Strs(args)))
}
