The class of widget-windows that are instantiated whenever a
vertical-scroll-bar is added to a
window. Probably not of concern to applications unless it needs to
intercept low-level window events of a vertical-scroll-bar subclass or
otherwise add methods to the widget-window of a vertical-scroll-bar. See os-widget-window.
A diagram of window and widget classes is shown in Widget and window classes in cgide.htm.
