@class wxBookCtrlBase
- @wxheader{bookctrl.h}
- @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.

+ It allows the program to examine the current page (which can be retrieved
