/** Size of the menu starting from this menu item */
/** Size of the menu starting from this menu item.
This method counts all menu items starting with \p this menu item,
including all menu items in the same (sub)menu level, all nested
submenus, \b and the terminating empty (0) menu item.
It does \b not count menu items referred to by FL_SUBMENU_POINTER
menu items (except the single menu item with FL_SUBMENU_POINTER).
All menu items counted are consecutive in memory (one array).
Example:
\code
schemechoice = new Fl_Choice(X+125,Y,140,25,"FLTK Scheme");
schemechoice->add("none");
schemechoice->add("plastic");
schemechoice->add("gtk+");
schemechoice->add("gleam");
printf("schemechoice->menu()->size() = %d\n", schemechoice->menu()->size());
\endcode
Output:
schemechoice->menu()->%size() = 5
