GtkSharp/glib/Object.cs
Mike Kestner c3b0ed58d9 2001-10-30 Mike Kestner <mkestner@speakeasy.net>
* codegen/defs-parse.pl : streamline mkdir stuff.  Prune the object
	list back to just Window for now. Suppress generation of the Prop
	get/set accessor methods.
	* codegen/gdk-types.defs : Updated the 2button/3button event types
	since I don't feel like automangling them now.
	* gdk/Event.cs : Killed the now redundant EventType declaration.
	* glib/Object.cs : Override the Equals and GetHashCode methods.
