wxSashLayoutWindow responds to OnCalculateLayout events generated
by wxLayoutAlgorithm. It allows the
application to use simple accessors to specify how the window should be
laid out, rather than having to respond to events. The fact that
the class derives from wxSashWindow allows sashes to be used if required,
to allow the windows to be user-resizable.
