Probably depends on if you're setting the callback for the widget,
or the callback for the items.
Each item can have its own callback and userdata.
Also, the Menu widget itself can also have its own callback + userdata.
(The latter is used for items that have no callback of their own, IIRC.)
If you're setting the callback for the widget, then
w->userdata() should have any user_data() you'd set.
But if you're setting the item's individual callbacks,
then to access that item's userdata, your callback would have
to first find the last item picked (with 'mvalue()')
and then access its user_data(), eg:
const Fl_Menu_Item *item = w->mvalue(); // get last picked item
long i = (long)item->user_data(); // get user data for
that item
..or something like that.
