You forgot, that programmers *love* recursions!
void Recur(Fl_Group *pG)
{
for ( int i=0; i<pG->children(); i++ )
{ // walk all groups children
const char *classname = "?";
Fl_Widget *w = win->child(i);
if (Fl_Group* pR= dynamic_cast< Fl_Group* >(w)) Recur(pR);
// Yes, that's it! :O)
else
{

I'm not sure, wether all the brackets are right, but even if not
compilable this should show the idea.
