Add a function to determine if a window is the focus widget within its

Wed Oct 25 14:17:43 2000  Owen Taylor  <otaylor@redhat.com>

	* gtk/gtkwidget.[ch] (gtk_widget_is_focus): Add a function
	to determine if a window is the focus widget within
	its toplevel.

	* gtk/gtkcontainer.[ch]: Fix the return type of ::focus
	to be boolean.

	* gtk/gtkcontainer.c (gtk_container_real_focus): Move handling
	of the case where the container CAN_FOCUS to here instead
	of having it in each individual move-the-focus place.

	* gtk/gtkcontainer.c: Rewrite handling of left-right and up-down
	focusing to be geometric in a much more obvious sense. Arrowing
	around is still non-intuitive because it isn't perfect and
	because entries, etc, grab the arrow keys, but it at least
	usually will do what you expect now.

	* gtk/gtknotebook.[ch]: Many cleanups. Moved docs inline in this
	file.

	* gtk/gtknotebook.c: Change tabs to be a single item in
	the focus chain. Make movement of focus on tabs with arrow
	keys wrap around.

	* gtk/gtknotebook.c (gtk_notebook_find_child): Add
	CHECK_FIND_CHILD macro to give informative error messages
	instead of silent returns.

	* gtk/gtknotebook.c (gtk_notebook_init): Set the RECEIVES_DEFAULT
	flag since we handle GdkReturn on the tabs.

	* gtk/gtknotebook.c (gtk_notebook_expose_tabs): Invalidate
	windows rather than sending expose events directly.

	* gtk/gtknotebook.[ch] docs/Changes-2.0.txt: Move structure
	definition for GtkNotebookPage into .c file, since it is private.

	* gtk/testgtk.c (create_notebook): Add option for
	testing borderless notebook.

	* gtk/testgtk.c (page_switch): Removed egregious poking
	around in GTK+ internals.

	* docs/widget-system.txt: Remove references to GTK_REDRAW_PENDING.

	* gtk/gtkclist.[ch]: Remove key press handler, handle focusing
	properly through gtk_clist_focus. Make the title headers a
	single item in the tab-focus chain, and make left-right wrap
	around.

	* gtk/gtkwindow.c (gtk_window_focus): Add a custom
	focus method so that wrapping around works properly.

	* gtk/gtktreeview.c: Remove calls to gtk_container_set_focus_child() -
	that is handled for the widget now.
