   2
   3 A menu item represents an item in a menu. Note that you usually don't have to
   4 deal with it directly as \helpref{wxMenu}{wxmenu} methods usually construct an
   5 object of this class for you.
   6
   7 Also please note that the methods related to fonts and bitmaps are currently
   8 only implemented for Windows.
