started with then use wxFIXED\_MINSIZE.}

\func{wxSizerItem *}{GetItem}{\param{wxWindow* }{window}, \param{bool }{recursive = false}}
\func{bool}{Remove}{\param{size\_t }{index}}
-Removes a child from the sizer and destroys it. \arg{sizer} is the wxSizer to be removed,
-\arg{index} is the position of the child in the sizer, typically 0 for the first item.
+Removes a child from the sizer and destroys it if it is a sizer or a spacer,
+but not if it is a window (because windows are owned by their parent window,
+not the sizer). \arg{sizer} is the wxSizer to be removed,
+\arg{index} is the position of the child in the sizer, e.g. $0$ for the first item.
This method does not cause any layout or resizing to take place, call
\helpref{wxSizer::Layout}{wxsizerlayout} to update the layout "on screen" after removing a
child from the sizer.
-{\bf NB:} The method taking a wxWindow* parameter is deprecated. For historical reasons
-it does not destroy the window as would usually be expected from Remove. You should use
-\helpref{wxSizer::Detach}{wxsizerdetach} in new code instead. There is currently no wxSizer
-method that will both detach and destroy a wxWindow item.

+
+The detached child is removed {\bf only} if it is a sizer or a spacer

\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 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
-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, 0, wxEXPAND | wxBORDER, 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.
+you can now write
-Note that by specification, all methods of wxSizerFlags return the wxSizerFlags object itself to ease the calling of multiple methods at a time.
+\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);
+
+ 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.
