Hmm, why don't you just use the pointer to the Fl_Menu_Item you want to change and call the do_callback method?
http://www.fltk.org/doc-1.3/structFl__Menu__Item.html Of course you will need to get the pointer first: Use: Fl_Menu_Item* pItem= mymenu->find_item("path/to/menuitem"); or Fl_Menu_Item* pItem= mymenu->find_item(callback_of_menuitem); More methods here: http://www.fltk.org/doc-1.3/classFl__Menu__.html I hope this takes care of your problem.
