 134 wx.SashLayoutWindow responds to OnCalculateLayout events generated by
 135 wxLayoutAlgorithm. It allows the application to use simple accessors to
 136 specify how the window should be laid out, rather than having to respond
 137 to events. The fact that the class derives from wx.SashWindow allows sashes
 138 to be used if required, to allow the windows to be user-resizable.
 139
 140 The documentation for wx.LayoutAlgorithm explains the purpose of this class
 141 in more detail.
