/**
@class wxBookCtrlBase
@todo Document this class.
A book control is a convenient way of displaying multiple pages of information,
displayed one page at a time. wxWidgets has five variants of this control:
@li wxChoicebook: controlled by a wxChoice
@li wxListbook: controlled by a wxListCtrl
@li wxNotebook: uses a row of tabs
@li wxTreebook: controlled by a wxTreeCtrl
@li wxToolbook: controlled by a wxToolBar
This abstract class is the parent of all these book controls, and provides
their basic interface.
This is a pure virtual class so you cannot allocate it directly.

with wxBookCtrlEvent::GetOldSelection) and to veto the page change by calling
wxNotifyEvent::Veto if, for example, the current values in the controls
of the old page are invalid.
