GtkSharp/generator/Ctor.cs
Rachel Hestilow fb1256d2f3 2002-07-13 Rachel Hestilow <hestilow@ximian.com>
* parser/Gnome.metadata, Gtk.metadata: More conflict
	fixes.
	* parser/build.pl: Fully qualify all lib names. (Gtk+ packages
	are now LFS-compliant in Debian...)
	* parser/gapi2xml.pl: Fix for whitespace in fields, defines,
	and docs.

	* generator/BoxedGen.cs: Remove extraneous CallByName definition,
	add "override" keyword to FromNative.
	(Generate): Generate methods after fields.
	* generator/ClassBase.cs: Change CallByName, FromNative to virtual.
	(.ctor): Ignore "hidden" nodes. Set container on signal.
	(GenSignals, GenMethods): Add "implementor" argument for interface
	use.
	(Get(Method|Signal|Property)Recursively): Rework to correctly
	recurse interfaces.
	(Implements): Added.
	* generator/Ctor.cs (Initialize): Move clash initialization completely
	out of Generate, so we can check for collisions.
	* generator/Method.cs (GenerateDeclCommon): Check for duplicates,
	for "new" keyword.
	(Generate): Add "implementor" argument.
	* generator/ObjectGen.cs (Generate): Initialize ctor clashes on
	this and all parents, before generating.
	(Ctors, InitializeCtors): Added.
	* generator/Signal.cs: Store the container_type, check for
	collisions.
	* generator/StructGen.cs: Add "override" keyword to overriden methods.

	* gtk/FileSelection.custom (ActionArea): Add "new" keyword.
