GtkSharp/gtk/Widget.custom
Mike Kestner c1564a1288 2005-05-10 Mike Kestner <mkestner@novell.com>
* gtk/Object.custom : Dispose on a Destroyed event.
	* gtk/Widget.custom : rework the parent_set hack to go direct to
	the native signal instead of using the event so we avoid rewrapping of
	already destroyed parents.
