//
// "$Id$"
//
// An example of using Fl_Menu_Bar's add() to dynamically create menubars
//
// Menu bars can be created several ways. Using add() allows
// dynamically creating a menubar using a 'pathname' syntax.
// Use if you're creating items dynamically, or if you're making
// menubars by hand (as opposed to using fluid), as it's easier
// to type and read.
//
// In this case we're using one callback for all items,
// but you can make unique callbacks for each item if needed.
