  16     @class wxTreebook
  17
  18     This class is an extension of the wxNotebook class that allows a tree
  19     structured set of pages to be shown in a control. A classic example is a
  20     netscape preferences dialog that shows a tree of preference sections on
  21     the left and select section page on the right.
  22
  23     To use the class simply create it and populate with pages using
  24     InsertPage(), InsertSubPage(), AddPage(), AddSubPage().
  25
  26     If your tree is no more than 1 level in depth then you could simply use
  27     AddPage() and AddSubPage() to sequentially populate your tree by adding at
  28     every step a page or a subpage to the end of the tree.
