The origional code has something that looks like this:

   SetWindowAttributes attribs;
   Window wnd;
   attribs.backing_store = Always;
   wnd = XCreateWindow(display, DefaultRootWindow(display),
                0, 0, width, height, 0, 8, InputOutput, visual,
                CWBackingStore | CWBackPixel, &attribs);

Is there any way to cause this to happen in GTK/GDK?

Thanks again!
