  13
  14 A menu item represents an item in a menu. Note that you usually don't have to
  15 deal with it directly as \helpref{wxMenu}{wxmenu} methods usually construct an
  16 object of this class for you.
  17
  18 Also please note that the methods related to fonts and bitmaps are currently
  19 only implemented for Windows and GTK+.
