Sun Nov 4 16:02:08 2001 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.[ch]: Add a function gdk_window_invalidate_maybe_recurse() for use in "shallow invalidation" of a widget. (Windows belonging to the widget, but not to the widget's children) * gtk/gtkprivate.h gtk/gtkwidget.c gtk/gtksizegroup.c: Add private flags GTK_ALLOC_NEEDED, GTK_REQUEST_NEEDED. These flags are set up on ancestors up to the resize container on queue_resize. Size requests only actually take place if GTK_REQUEST_NEEDED, size allocations only take place if GTK_ALLOC_NEEDED or the size changed. * gtk/gtkcontainer.c gtk/gtkwidget.c: Remove container->resize_widgets and the RESIZE_NEEDED flag since the above flags are sufficient to figure out what needs to be resized/reallocated. Remove code manipulating container->resize_widget. * gtk/gtkwidget.[ch]: Add gtk_widget_set_redraw_on_alloc(); this allows widgets to turn off being automatically invalidated is when they are resized. * gtk/gtkwidget.[ch] (gtk_widget_size_allocate): Invalidation when a widget is resized or moved is "shallow" as described above - only the windows that need to be invalidated are invalidated. * gtk/gtkbox.c gtk/gtktable.c gtk/gtkalignment.c docs/Changes-2.0.txt: Make these widget's init functions call gtk_widget_set_redraw_on_allocate(widget,FALSE). * gtk/gtkwindow.c (gtk_window_configure_event): Call _gtk_container_queue_resize(), since we don't want redrawing. (Probably could be done for other calls to gtk_widget_queue_resize() in gtkwindow.c, but this is the most important one.) * gtk/gtkwindow.c (gtk_window_move_resize): Don't call gtk_widget_queue_draw() - size_allocate() handles that as appropriate. * gtk/gtkframe.c (gtk_frame_size_allocate): Invalidate instead of queue_clear() to avoid invalidating children.
