Thanx a lot for your example!
Now all is clear. I look at your program and at the source code
_generated by fluid_.
You declare several menu item (Fl_Menu_Items[]), and for one of them,
you set a FL_SUBMENU_POINTER , and a user_data which means in this case
a pointer to a submenu...
But in fluid, _my error_ is that I create "Recent" as a "Submenu". In
such a case, fluid generate a sequence like :
{"Recent", 0, 0, 0, 64, FL_NORMAL_LABEL, 2, 12, 0},
{0,0,0,0,0,0,0,0,0}, // the end of the submenu
{"Save", 0, (Fl_Callback*)save, 0, 128, FL_NORMAL_LABEL, 2, 12, 0},
... giving me unexpected results. Now, I decalre "recent" as a normal
Fl_Menu_Item =>
{"Recent", 0, 0, 0, 0, FL_NORMAL_LABEL, 0, 14, 0},
{"Save", 0, (Fl_Callback*)save, 0, 128, FL_NORMAL_LABEL, 2, 12, 0},
In my code, I declare a pointer to "Recent" and I make :
last->flags |= FL_SUBMENU_POINTER;
last->user_data= a_function_giving_a_dynamic_array_of_Fl_Menu_Items();
And that works.
