GtkSharp/glib/SignalCallback.cs
Mike Kestner 8b85bf647a 2002-07-16 Mike Kestner <mkestner@speakeasy.net>
* generator/ClassBase.cs : make MarshalType virtual.
	* generator/Parameters.cs : add Parameter class and Indexer.
	* generator/Signal.cs : Now use Parameters.
	(GetHandlerName): New abstraction of name handling.
	(GenerateDecls): use GetHandlerName.
	(GenComments): make private.
	(GenHandler): New. Generate custom event handlers and args.
	(Generate): use GenHandler. Pass args type to SignalHandler.
	* generate/SignalHandler.cs : store args type. Generate handler
	  dependent args and use MulticastDelegate.DynamicInvoke.
	* generate/StructGen.cs : override MarshalType.
	* glib/SignalCallback.cs : store a MulticastDelegate and args type
	* sample/*.cs : use new DeleteEventHandler
