cannot use wxSizer directly; instead, you will have to use one of the sizer
classes derived from it. Currently there are \helpref{wxBoxSizer}{wxboxsizer},
\helpref{wxStaticBoxSizer}{wxstaticboxsizer},
-\helpref{wxGridSizer}{wxgridsizer}
-\helpref{wxFlexGridSizer}{wxflexgridsizer} and \helpref{wxGridBagSizer}{wxgridbagsizer}.
+\helpref{wxGridSizer}{wxgridsizer},
+\helpref{wxFlexGridSizer}{wxflexgridsizer},
+\helpref{wxWrapSizer}{wxwrapsizer}
+ and \helpref{wxGridBagSizer}{wxgridbagsizer}.
The layout algorithm used by sizers in wxWidgets is closely related to layout
in other GUI toolkits, such as Java's AWT, the GTK toolkit or the Qt toolkit. It is
method to determine where the drawing operations should take place.
+Please notice that sizers, like child windows, are owned by the library and
+will be deleted by it which implies that they must be allocated on the heap.
+However if you create a sizer and do not add it to another sizer or window, the
+library wouldn't be able to delete such an orphan sizer and in this, and only
+this, case it should be deleted explicitly.
+
\pythonnote{If you wish to create a sizer class in wxPython you should
derive the class from {\tt wxPySizer} in order to get Python-aware
capabilities for the various virtual methods.}

\func{void}{SetSizeHints}{\param{wxWindow* }{window}}
-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.
+
+This method is implicitly used by \helpref{wxWindow::SetSizerAndFit}{wxwindowsetsizerandfit}
+which is commonly invoked in the constructor of a toplevel window itself (see
+the sample in the description of \helpref{wxBoxSizer}{wxboxsizer}) if the
+toplevel window is resizable.

\section{\class{wxSizerFlags}}\label{wxsizerflags}
-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}
+
+you can now write
-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.
+\begin{verbatim}
+ sizer->Add(ctrl, wxSizerFlags().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.
+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);
-Note that by specification, all methods of wxSizerFlags return the wxSizerFlags object itself to ease the calling of multiple methods at a time.
+ 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.
