+\subsubsection{Hiding controls using sizers}\label{sizershiding}
+
+You can hide controls contained in sizers the same way you would hide any control,
+using the \helpref{wxWindow::Show}{wxwindowshow} method.
+
+However, wxSizer also offers a separate method which can tell the sizer not to
+consider that control in its size calculations. To hide a window using the sizer,
+call \helpref{wxSizer::Show}{wxsizershow}. You must then call Layout on the sizer
+to force an update.
+
+This is useful when hiding parts of the interface, since you can avoid removing
+the controls from the sizer and having to add them back later.
+
+Note: This is supported only by wxBoxSizer and wxFlexGridSizer.

In order to query the size of notebook page, this page needs to have its
own sizer, otherwise the wxNotebookSizer will ignore it. Notebook pages
get their sizer by assigning one to them using \helpref{wxWindow::SetSizer}{wxwindowsetsizer}
-and setting the auto-layout option to TRUE using
+and setting the auto-layout option to true using
\helpref{wxWindow::SetAutoLayout}{wxwindowsetautolayout}. Here is one
example showing how to add a notebook page that the notebook sizer is
aware of:
// Add controls to panel and panelsizer here...
- panel->SetAutoLayout( TRUE );
+ panel->SetAutoLayout( true );
panel->SetSizer( panelsizer );
