derive the class from {\tt wxPySizer} in order to get Python-aware
capabilities for the various virtual methods.}

-Tell the sizer to set (and \helpref{Fit}{wxsizerfit}) the minimal size of the \arg{window} to
-match the sizer's minimal size. This is commonly done in the constructor of the window itself,
-see sample in the description of \helpref{wxBoxSizer}{wxboxsizer} if the window is resizable
-(as are many dialogs under Unix and frames on probably all platforms).
+This method first calls \helpref{wxSizer::Fit}{wxsizerfit} and then
+\helpref{SetSizeHints}{wxtoplevelwindowsetsizehints} on the {\it window}
+passed to it. This only makes sense when {\it window} is actually a
+\helpref{wxTopLevelWindow}{wxtoplevelwindow} such as a wxFrame or a
+wxDialog, since SetSizeHints only has any effect in these classes.
+It does nothing in normal windows or controls.

+toplevel window is resizable.

-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 | wxALL, 10);
+\end{verbatim}
-Normally, when you add something to a sizer via \helpref{wxSizer::Add}{wxsizeradd}, you have to specify a lot of flags and parameters. This can be unwieldy.
+you can now write
-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.
+\begin{verbatim}
+ sizer->Add(ctrl, wxSizerFlags().Expand().Border(10));
+\end{verbatim}
-Note that by specification, all methods of wxSizerFlags return the wxSizerFlags object itself to ease the calling of multiple methods at a time.
+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);
+
+ sizer->Add(ctrl1, flagsExpand);
+ sizer->Add(ctrl2, flagsExpand);
+\end{verbatim}
+
+Note that by specification, all methods of wxSizerFlags return the wxSizerFlags
+object itself to allowing chaining multiple methods calls like in the examples
+above.
