that's quite another approach than mine - but works perfect. Thanks for that!
In the meantime I found out how to work with add:
int n = 3;
Fl_Menu_Item *pop = new Fl_Menu_Item[n];
pop->add( "First item", 0, 0, 0, 0 );
pop->add( "Second item", 0, 0, 0, 0 );
..
pop->popup( 10, 10, 0, 0, 0 );
Apparently add() may be used only after having allocated an array of
Fl_Menu_Items whose size is one more than the number of Items to be added.
I think I'll be using Fl_Menu_Button.
Thanks again and bye
