GtkSharp/generator/Property.cs
Rachel Hestilow 414a14d93e 2002-06-24 Rachel Hestilow <hestilow@ximian.com>
* glib/UnwrappedObject.cs: New class which holds an IntPtr.
	This is used in Value so that we can retrieve the IntPtr itself
	for an object property.

	* glib/Value.cs: Add UnwrappedObject cast operator.

	* glib/Property.cs: If the retrieved value is an object,
	and there is no wrapper object, create a new one.
