Tue Nov 13 21:00:59 2001  Jonathan Blandford  <jrb@redhat.com>

	* gtk/gtktreemodelsort.c (gtk_tree_model_sort_class_init): new
	"model" construct property for language bindings.

	* gtk/gtktreestore.c (gtk_tree_store_set_column_types): New
	function to let you set the column types of a GtkTreeStore for
	language bindings.

	* gtk/gtkliststore.c (gtk_list_store_set_column_types): ditto.
