Thu Jun 28 23:53:31 2001 Tim Janik <timj@gtk.org> * gtk/gtkwidget.c (gtk_widget_hide): !GTK_OBJECT_DESTROYED() -> GTK_WIDGET_REALIZE() for resize queueing. * gtk/gtkmain.c (gtk_main_do_event): !GTK_OBJECT_DESTROYED() -> GTK_WIDGET_REALIZE() for post event delivery destruction upon GDK_DESTROY. * gtk/gtkwidget.c: added GtkWidget::event-after notification signal, to sompensate for former (pre-2.0) connect_after() facility. (gtk_widget_send_expose): (gtk_widget_event): assert the widget is realized, since event delivery to non-realized widgets is essentially a bug. event handlers should be able to unconditionally rely on widget->window (unless they emit events on their own which can trigger widget destruction). (gtk_widget_event_internal): removed old outdated GTK_OBJECT_DESTROYED() logic. event delivery happens as follows: a) emission of GtkWidget::event (RUN_LAST handler). returns was_handled. b) if !was_handled in (a) and the widget is still realized, emit event- specific signal (RUN_LAST handler). returns was_handled. c) emission of GtkWidget::event-after for notification if the widget is still realized (regardless of was_handled from previous stages, no class handler). no return value. d) was_handled gets passed on to caller, to determine further propagation. if the widget got unrealized meanwhile, was_handled is returned as TRUE. * gdk/gdkevents.[hc]: added gdk_event_get_root_coords() and gdk_event_get_coords().
