GtkSharp/generator/EnumGen.cs
Rachel Hestilow fe699e9fbb 2003-05-29 Rachel Hestilow <rachel@nullenvoid.com>
* gconf/Value.cs: Update to use new string marshalling.

	* generator/StringGen.cs, ConstStringGen.cs: Added.
	* generator/IGeneratable.cs: Add new method ToNativeReturn.
	* generator/CallbackGen.cs: Implement ToNativeReturn. Call
	ToNativeReturn for the return statement. Fix a couple of
	places where s_ret was being used incorrectly for m_ret.
	* generator/ClassGen.cs, EnumGen.cs, ManualGen.cs,
	SimpleGen.cs, StructBase.cs: Implement ToNativeReturn.
	* generator/SignalHandler.cs: Call ToNativeReturn for the
	return statement, instead of CallByName.
	* generator/SymbolTable.cs: Use StringGen for gchar, char,
	and gunichar, and ConstStringGen for their const variants.
	Add a new method wrapper for ToNativeReturn.
	(Trim): Add a special-case for const strings so that the
	const is not stripped. Otherwise there is no way of
	resolving the const case.

	* glade/XML.custom: Update to use new string marshalling.

	* glib/Marshaller.cs: Added.
	* glib/GException.cs, Markup.cs, ObjectManager.cs,
	Value.cs: Update to use new string marshalling.
	* glib/Object.cs: Remove old g_type_name DllImport
	as it is no longer used.

	* glue/fileselection.c (gtksharp_file_selection_get_fileop_entry):
	Mark this as const return.

	* gtk/ColorSelection.custom, FileSelection.custom,
	SelectionData.custom: Update to use new string marshalling.
