Jonathan Blandford 92841cb95a Make a GtkCellEditable (get_widget_window_size): Change to let it honor
Tue Sep 25 12:34:42 2001  Jonathan Blandford  <jrb@redhat.com>

	* gtk/gtkentry.c: Make a GtkCellEditable
	(get_widget_window_size): Change to let it honor size_allocate
	when a CellEditable.

	* gtk/gtktreeview.c: M-x clean-line-ends.  Lots of focus and
	editable changes.
	(gtk_tree_view_set_cursor): Now you can set the cursor
	horizontally, as well as start editing.

	* gtk/gtkstyle.c (gtk_default_draw_check): changing toggle drawing
	code to look more like the other check buttons.

	* gtk/gtkcellrenderertoggle.c (gtk_cell_renderer_toggle_get_size):
	Change the way we calculate cell size.

	* gtk/gtkmarshal.list (VOID:STRING,STRING): new marshaller.

	* demos/gtk-demo/sizegroup.c: Add mnemonics.

	* gtk/gtkcellrenderer.c (gtk_cell_renderer_get_size): Fix docs.
	Fix logic.

	* gtk/gtkcellrenderertext.c: Change to be editable.

	* gtk/gtkcellrenderertoggle.c: Change to be activatable.

	* test/testtreesort.c: Fix misspelling

	* test/testreecolumns.c: Add mnemonics.

	* test/testreeedit.c: New test program.

* DO NOT!!! I REPEAT DO NOT! EVER LOOK AT THIS CODE AS AN EXAMPLE OF WHAT YOUR
* CODE SHOULD LOOK LIKE.
*
* IT IS VERY CONFUSING, AND IS MEANT TO TEST A LOT OF CODE IN THE TREE. WHILE
* IT IS ACTUALLY CORRECT CODE, IT IS NOT USEFUL.
