\section{\class{wxMenuItem}}\label{wxmenuitem}

A menu item represents an item in a menu. Note that you usually don't have to
deal with it directly as \helpref{wxMenu}{wxmenu} methods usually construct an
object of this class for you.

Also please note that the methods related to fonts and bitmaps are currently
only implemented for Windows and GTK+.
