That is the proper way. The "const" is kind of a relic from old times and hints at the fact that using another "add()" may change the base pointer to your menu structure. Looking at the 12 year-old api today, a menu s of course nothing but another widget hierarchy, but back then, there were no submenus and an array was chosen to create a menu bar. FLTK2 is much better in this respect by using said hierarchy.
