... or, what you might want is to use "X+W" instead of "W" to
draw a line over the full width of your widget.
Note that you should not position your window to (0,0,...), but
you'd better use (50,50,...). Also, the use of a static variable
effectively prevents correct resizing of your widget, but this was
not asked here.
