GtkSharp/generator/Ctor.cs
Rachel Hestilow 1f4ff5bb86 2002-06-24 Rachel Hestilow <hestilow@ximian.com>
* glib/EnumWrapper.cs: New class which holds an enum int.

	* glib/Value.cs: Add support for glib enum types. We needed
	to use EnumWrapper for this because otherwise the int operator
	wouldn't know which glib function to use.

	* generator/BoxedGen.cs, ClassBase.cs, Ctor.cs, EnumGen.cs,
	InterfaceGen.cs, Method.cs, ObjectGen.cs, Signal.cs, StructGen.cs:
	Create more doc stubs.

	* generator/Property.cs: Generate enum values correctly.

	* generator/Ctor.cs: Refactor generation to honor metadata-specified
	collision preference.

	* parser/Gtk.metadata: Added constructor collision preferences to
	all known clashes.

	* parse/Gdk.metadata: Added (for Pixbuf clashes).
