grow-box-spacer-pane% : class?

  superclass: pane%

A grow-box-spacer-pane% object is intended for use as a lightweight spacer in the bottom-right corner of a frame, rather than as a container. On Mac OS X, a grow-box-spacer-pane% has the same width and height as the grow box that is inset into the bottom-right corner of a frame. On Windows and Unix, a grow-box-spacer-pane% has zero width and height. Unlike all other container types, a grow-box-spacer-pane% is unstretchable by default.
