I had a similar question some time ago

So perhaps the easiest thing to do is just put things where you
want them to be.
Fl_Widget** a = array();
Fl_Widget* tmp = a[2];
a[2] = a[1];
a[1] = a[0];
a[0] = tmp;
A couple of gotchas to watch out for... (1) Fl_Scroll has 2
more children than you think it does, and they'll get moved back
to the last 2 spots in the array no matter what you do. (2) After
you're done moving the children around as you described, the
group tab order will be 3-1-2-(stop). The tab key won't advance
the focus from 2->3. Both of these little issues apply no matter
what method you use to move the children around, AFAIK.
