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.
