Quote from fltk 1.3.0 , 30.77.2.4 :
**int Fl Menu Item::add ( const char mytext, int sc, Fl_Callback cb, void
data = 0, int myflags = 0 ) Adds an item.
The text is split at â/â characters to automatically produce submenus
(actually a totally unnecessary feature as you can now add submenu titles
directly by setting SUBMENU in the flags)**
As you can see fltk documentation calls '/' actually a totally unnecessary
feature. Can you explain me above para in easy word and how does "SUBMENU" (did
he mean FL_SUBMENU ? ) in flags does that?
Also I could'nt understand what's use of flag FL_SUBMENU_POINTER? . Please
teach with an easy example?
Thanks a lot , I really appreciate the help :)
