Fix #145463, reported by Michael Natterer.

2004-12-09  Matthias Clasen  <mclasen@redhat.com>

	Fix #145463, reported by Michael Natterer.

	* gtk/gtkcellrenderer.h (struct _GtkCellRenderer): Add an
	editing flag to keep track of when editing is done.

	* gtk/gtkcellrenderer.h:
	* gtk/gtkcellrenderer.c (gtk_cell_renderer_stop_editing): New
	function to replace gtk_cell_renderer_editing_canceled().
	Deprecate gtk_cell_renderer_editing_canceled().

	* gtk/gtkcellrenderertext.c (gtk_cell_renderer_text_editing_done):
	* gtk/gtkcellrenderercombo.c (gtk_cell_renderer_combo_editing_done):
	* gtk/gtktreeview.c (gtk_tree_view_stop_editing):
	Use gtk_cell_renderer_stop_editing().
