gtk2/gtk/gtkclist.h
Stefan Jeske c8df83a2fe new enum GtkSortType. 
Wed Aug  5 21:12:37 1998  Stefan Jeske  <stefan@gtk.org>

	* gtk/gtkenums.h: new enum GtkSortType.

	* gtk/gtkclist.h:
	* gtk/gtkclist.c:
	Added sorting capabilities to GtkCList. New APIs :
	gtk_clist_set_compare_func, gtk_clist_set_sort_column,
	gtk_clist_set_sort_type, gtk_clist_sort, gtk_clist_set_auto_sort.
	New internal functions : default_compare, merge, mergesort.

	(gtk_clist_append): This is just a wrapper for gtk_clist_insert now.

	(gtk_clist_insert): Modified to handle gtk_clist_append and the
	auto sort flag. Changed the return value from void to gint to
	return the row number where the element was actually inserted.

	(gtk_clist_swap_rows): Return immediately if auto sort flag is set.

	* gtk/gtkctree.h:
	* gtk/gtkctree.c:
	Removed the auto_sort flag, replaced ctree->node_compare with
	clist->compare all over the place, modified default_compare to
	match clist's needs. Removed API´s : gtk_ctree_set_auto_sort,
	gtk_ctree_set_compare_func. Removed GtkCTreeCompareFunc typedef.

	* gtk/testgtk.c: Modified clist/ctree samples to demonstrate
	sorting. The lists can be sorted by a column by clicking the
	corresponding title button.
