The source project of this merge request has been removed.

Ghost User requested to merge (removed):master into master Sep 20, 2021

The impetus of this patch were the invalid return types of ButtonHandler, DrawHandler and SizeChangeHandler.

The C++ implementation internally uses partial template specialization which is needed to separate the type "void" from other data types.

The file gtk.cc contains comments with HTTP links to Gtk and Xfce documentation which can be used to verify the handler function signatures.
