Sizers, as represented by the wxSizer class and its descendants in
the wxWindows class hierarchy, have become the method of choice to
Within wxDesigner, this stretch factor gets set from the {\it Option} menu.
+\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.

\helpref{wxBoxSizer}{wxboxsizer} can lay out its children either vertically
It is the unique feature of a box sizer, that it can grow in both directions (height and
width) but can distribute its growth in the main direction (horizontal for a row) {\it unevenly}
among its children. In our example case, the vertical sizer is supposed to propagate all its
-height changes to only the text area, not to the button area. This is determined by the {\it option} parameter
+height changes to only the text area, not to the button area. This is determined by the {\it proportion} parameter
when adding a window (or another sizer) to a sizer. It is interpreted
as a weight factor, i.e. it can be zero, indicating that the window may not be resized
at all, or above zero. If several windows have a value above zero, the value is interpreted

- SetAutoLayout( TRUE ); // tell dialog to use sizer
- SetSizer( topsizer ); // actually set the sizer
+ SetSizer( topsizer ); // use the sizer for layout
- topsizer->Fit( this ); // set size to minimum size as calculated by the sizer

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 );

separately.
+\subsection{CreateButtonSizer}\label{createbuttonsizer}
+
+As a convenience, CreateButtonSizer ( long flags ) can be used to create a standard button sizer
+in which standard buttons are displayed. The following flags can be passed to this function:
+
+
+\begin{verbatim}
+ wxYES_NO // Add Yes/No subpanel
+ wxYES // return wxID_YES
+ wxNO // return wxID_NO
+ wxNO_DEFAULT // make the wxNO button the default, otherwise wxYES or wxOK button will be default
+
+ wxOK // return wxID_OK
+ wxCANCEL // return wxID_CANCEL
+ wxHELP // return wxID_HELP
+
+ wxFORWARD // return wxID_FORWARD
+ wxBACKWARD // return wxID_BACKWARD
+ wxSETUP // return wxID_SETUP
+ wxMORE // return wxID_MORE
