+This method should be overridden to return \texttt{true} if this window has
+multiple pages. All standard class with multiple pages such as 
+\helpref{wxNotebook}{wxnotebook}, \helpref{wxListbook}{wxlistbook} and 
+\helpref{wxTreebook}{wxtreebook} already override it to return \texttt{true}
+and user-defined classes with similar behaviour should do it as well to allow
+the library to handle such windows appropriately.
