/**
@class wxTreebook
This class is an extension of the wxNotebook class that allows a tree
structured set of pages to be shown in a control. A classic example is a
netscape preferences dialog that shows a tree of preference sections on
the left and select section page on the right.
To use the class simply create it and populate with pages using
InsertPage(), InsertSubPage(), AddPage(), AddSubPage().
If your tree is no more than 1 level in depth then you could simply use
AddPage() and AddSubPage() to sequentially populate your tree by adding at
every step a page or a subpage to the end of the tree.
@beginEventEmissionTable{wxBookCtrlEvent}
@event{EVT_TREEBOOK_PAGE_CHANGED(id, func)}
The page selection was changed.
Processes a @c wxEVT_TREEBOOK_PAGE_CHANGED event.
@event{EVT_TREEBOOK_PAGE_CHANGING(id, func)}
The page selection is about to be changed.
Processes a @c wxEVT_TREEBOOK_PAGE_CHANGING event.
This event can be @ref wxNotifyEvent::Veto() "vetoed".
@event{EVT_TREEBOOK_NODE_COLLAPSED(id, func)}
The page node is going to be collapsed.
Processes a @c wxEVT_TREEBOOK_NODE_COLLAPSED event.
@event{EVT_TREEBOOK_NODE_EXPANDED(id, func)}
The page node is going to be expanded.
Processes a @c wxEVT_TREEBOOK_NODE_EXPANDED event.
