When a GtkWindow first appears after gtk_widget_show() is called on it, there is a moment during which it isn't yet rendered, and the X11 window's space is filled with all white background. I understand that this is an artifact of the normal allocate -> map -> expose progression. Is there a way to force that the window already has a rendered copy of itself available for the first refresh cycle, so that applications don't flicker to/from white at startup? I tried something like: GtkWidget* window = gtk_window_new (GTK_WINDOW_TOPLEVEL); ... add some children to the window ... GtkAllocation a; a.x = 0; a.y = 0; a.width = 100; a.height = 100; gtk_widget_realize (w); gtk_widget_size_allocate (w, &a); gdk_window_invalidate_rect (w->window, &w->allocation, TRUE); gdk_window_process_updates (w->window, TRUE); gtk_widget_show (w); That's an attempt to force allocation of the underlying X resources (and subsequent painting) before marking the window visible. The same flickering still happens at startup, though. Can anything else be done? _______________________________________________ gtk-list mailing list gtk-list@xxxxxxxxx http://mail.gnome.org/mailman/listinfo/gtk-list
