Grouping properties in a group (formerly "Which properties have changed?")

[vicenrico]

Is there any option to know which properties have changed? Or should I implement the usual propertychagelistener code?

Hi @vicenrico, you can try PropertiesComparator: first, create a CompareResults object:

CompareResults results = PropertiesComparator.compare(before, after);

then call results.getRightOnly(), results.getLeftOnly() or results.getDifferentValues().

For a real-world example, you can see: ConfigurationHandler.java, method doPost.

Ok. Thanks again. Now I have another problem. I have a label with foreground and background color, and and I'd like to group both properties in a group, like your example for Radiogroupfieldeditor. Is it possible this behaviour? Or is it only for radio buttons?

Sorry @vicenrico, this feature is missing. You can use isSeparate() (PreferenceDetails/IPreference) to emulate grouping of properties.

Happy new year!
