Havoc Pennington 5c37906778 hack on this a bit
2001-01-05  Havoc Pennington  <hp@redhat.com>

	* tests/testtreeview.c: hack on this a bit

	* gtk/gtktextlayout.c (gtk_text_layout_class_init):
	s/GTK_RUN_LAST/G_SIGNAL_RUN_LAST

	* gtk/gtktreemodelsimple.h (GTK_IS_TREE_MODEL_SIMPLE_CLASS):
	was spelled incorrectly
	(GTK_IS_TREE_MODEL_SIMPLE): ditto

	* gtk/gtktreeview.c (gtk_tree_view_set_headers_clickable): rename
	from gtk_tree_view_set_headers_active

	* gtk/gtktexttag.c:
	(gtk_text_tag_get_property): handle PROP_DIRECTION
	(gtk_text_tag_set_property): g_object_notify when we toggle the _set
	properties, bug 40235

	* gtk/gtktextiter.c (gtk_text_iter_forward_to_delimiters): rename
	forward_to_line_end
