-PRELIMINARY.
+Normally, when you add an item to a sizer via
+\helpref{wxSizer::Add}{wxsizeradd}, you have to specify a lot of flags and
+parameters which can be unwieldy. This is where wxSizerFlags comes in: it
+allows you to specify all parameters using the named methods instead. For
+example, instead of
+
+\begin{verbatim}
+ sizer->Add(ctrl, 0, wxEXPAND | wxBORDER, 10);
+\end{verbatim}
+
+you can now write
+
+\begin{verbatim}
+ sizer->Add(ctrl, wxSizerFlags().Expand().Border(10));
+\end{verbatim}
+
+This is more readable and also allows you to create wxSizerFlags objects which
+can be reused for several sizer items.
+\begin{verbatim}
+ wxSizerFlags flagsExpand(1);
+ flagsExpand.Expand().Border(10);

+\end{verbatim}
-This is where wxSizerFlags comes in. Instead of a bunch of flags and other stuff, you can use wxSizerFlags, which is a convenient class for doing so.
+Note that by specification, all methods of wxSizerFlags return the wxSizerFlags
