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