drawable-pane

The class of lisp-widget-windows that are instantiated whenever a drawable is added to a window. Probably not of concern to applications unless it needs to intercept low-level window events of a drawable subclass or otherwise add methods to the lisp-widget-window of a drawable. See lisp-widget-window.

A diagram of window and widget classes is shown in Widget and window classes in cgide.htm.
