Yes, you are right, it should be a gboolean and the widget
should not be deleted in the event, but that does not change anything.
The delete_callback only is called when you press the delete button
of the window manager, it is not called when you press the close
button or destroy the widget.

I do not see a reason to reference any objects here.
