gtk2/gtk/gtktypeutils.h
Tim Janik 347efc33b8 deleted most of the argument handling code, since that is now implemented 
Fri Jul 10 00:02:04 1998  Tim Janik  <timj@gtk.org>

	* gtk/gtkcontainer.h:
	* gtk/gtkcontainer.c: deleted most of the argument handling code, since
	that is now implemented in gtkarg.c. similar to gtk_object_args_collect,
	we now export a new function gtk_container_child_args_collect().
	for consistency with the object arguments, a few functions got renamed:
	gtk_container_child_arg_get -> gtk_container_child_get,
	gtk_container_child_arg_set -> gtk_container_child_set,
	gtk_container_child_arg_getv -> gtk_container_child_getv,
	gtk_container_child_arg_setv -> gtk_container_child_setv,
	gtk_container_add_with_argv -> gtk_container_addv.
	note, gtk_container_add_with_args() remained, because its equivalent
	would be gtk_container_add(,, ...) which would break all existing code.
	(gtk_container_add_child_arg_type): similar to gtk_object_add_arg_type,
	we expect the `arg_name' argument to be a const static string now.
	(gtk_container_get_child_arg_type): function removed.

Thu Jul  9 07:03:04 1998  Tim Janik  <timj@gtk.org>

	* gtk/gtkargcollector.c: new file which holds gtk_arg_collect_value().
	this is a static inline function that collects command line arguments
	from a va_list. this file can just be included in all places that
	need this functionality.

	* gtk/gtkarg.h:
	* gtk/gtkarg.c: new files which implement most of the argument
	handling stuff from gtkobject.c. also collected a few more
	gtk_arg_* utility functions from else places.

	* gtk/gtkobject.h:
	* gtk/gtkobject.c: moved most of the argument handling code into
 	gtkarg.c. we now export gtk_object_args_collect() as a non-public
	method with a blind va_list pointer.
	(gtk_object_add_arg_type): the `arg_name' argument is required to be a
	const static string now.
	(gtk_object_get_arg_type): function got removed.

	* gtk/gtkwidget.c:
	(gtk_widget_set):
	(gtk_widget_new): adaptions for gtk_object_args_collect().

	* gtk/gtktypeutils.c (gtk_type_init_builtin_types): changed the internal
 	fundamental type name so as to have a valid prefix, e.g. "bool"->
	"gboolean", "string"->"GtkString" and somesuch, left "void" as is,
	though that should probably be something like GtkNone since the
	type itself is called GTK_TYPE_NONE.
	even the internal type names need to avoid name clashes and must live
	in their own namespace, several code portions rely on that.
	we should relly have typedefs such as typedef gchar* GtkString; so the
	fundamental type names can be used for code dumpers just like with all
	the Gtk/Gdk types.
