Thu Nov 15 14:19:34 2001 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.c (gdk_window_invalidate_maybe_recurse): Cal gdk_window_invalidate_maybe_recurse() for recursion. (Soeren Sandmann) * gtk/gtkviewport.c: Make !redraw_on_allocate. (Soeren Sandmann) * gtk/gtkcontainer.c (gtk_container_expose): Call gtk_container_forall() not _foreach() to propagate, since we need to propagate exposes to internal children as well. * gtk/gtkwidget.c (gtk_widget_set_events, gtk_widget_add_events): Remove the restriction of only being able to call these on window widgets, since we have lots of NO_WINDOW widgets with windows now; for add events, recurse over the children of widget->window to find one owned by the widget. * gtk/gtkbutton.[ch]: Make a NO_WINDOW widget, using an input-only window to catch events. * gtk/gtktogglebutton.[ch]: Remove the code for switching between NO_WINDOW and WINDOW widgets based on the mode. * gtk/gtkcheckbutton.c gtk/gtkoptionmenu.c gtk/gtkclist.c gtk/gtktreeview.c: Adopt to NO_WINDOW change for GtkButton. * gtk/gtkrange.[ch]: Make into a NO_WINDOW widget. * gtk/gtkhscale.c, gtk/gtkvscale.c: Adopt to NO_WINDOW change for range. * gtk/gtknotebook.[ch]: Make into a NO_WINDOW widget. * docs/Changes-2.0.txt: Add a note about the NO_WINDOW changes.
