Thu Oct 25 16:27:29 2001  Jonathan Blandford  <jrb@redhat.com>

	* gtk/gtkrbtree.c (_gtk_rbnode_rotate_left): Add support for
	invalid nodes.
	 (_gtk_rbnode_rotate_right): Ditto.
	 (_gtk_rbtree_node_mark_invalid): New function.
	 (_gtk_rbtree_node_mark_valid): New function.

	* gtk/gtktreemodelsort.c (gtk_tree_model_sort_class_init): We're a
	GObject, not a GtkObject.
	(gtk_tree_model_sort_row_has_child_toggled): Rewrote to be more
	correct.
	(gtk_tree_model_sort_row_deleted): ditto.
	(gtk_tree_model_sort_{un,}ref_node): Fix.

	* gtk/gtktreeview.c: Protean incremental reflow support (commented
	out)

	* gtk/gtktreeview.h (GtkTreeViewSearchEqualFunc): change char *key
	to const char *key.

	* gtk/gtktreemodel.c (gtk_tree_row_reference_unref_path_helper):
	Important 1 line fix to fix a lot of refcounting woes.
