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{wxNotebookSizer}{wxnotebooksizer}, \helpref{wxGridSizer}{wxgridsizer}
+\helpref{wxGridSizer}{wxgridsizer}
\helpref{wxFlexGridSizer}{wxflexgridsizer} 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
based upon the idea of the individual subwindows reporting their minimal required
size and their ability to get stretched if the size of the parent window has changed.

children, which can be normal windows, empty space or other sizers, so that
a hierarchy of sizers can be constructed. Note that wxSizer does not derive from wxWindow

What makes sizers so well fitted for use in wxWidgets is the fact that every control

Shows or hides the {\it window}, {\it sizer}, or item at {\it index}.
To make a sizer item disappear or reappear, use Show() followed by Layout().
+Use parameter {\it recursive} to show or hide elements found in subsizers.
+
+Returns true if the child item was found, false otherwise.
Note that this only works with wxBoxSizer and wxFlexGridSizer, since they
are the only two sizer classes that can size rows/columns independently.
