See the fltk 1.3.0 example/menubar-add.cxx which shows how
to dynamically construct a menu bar, and also how to dynamically
change an item's state using find_item().
Also, there's several Fl_Menu oriented examples on my cheat page,
in particular:
http://seriss.com/people/erco/fltk/#Menu_ChangeLabel
find_item() can be used to find an item pointer by its 'pathname';
once you have the item's pointer, you can mess around with its
contents using the Fl_Menu_Item methods (see the docs).
Conversely, item_path() can be used to convert an item
back into a pathname.
If you ^F search the cheat page for "Fl_Menu", you'll find other
insights as well on working with Fl_Menu and its derivatives
(such as Fl_Menu_Bar)
