-Removes a child from the sizer and destroys it. {\it sizer} is the wxSizer to be removed,
-{\it 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.
