Hmm, doesn't Fl_Tile do this automatically?
The 'resizebox' demo that comes with FLTK show this pretty well
I think, as well as 'tile'.
Understanding the "resizable()" stuff (making an invisible box
with the right dimensions defining which widgets resize, and
which ones don't) is key to understanding how FLTK's resizing
behavior can be made to work without overriding resize.
Matt has a good description here:

You can do things procedurally too, overriding FLTK's customizable
behavior (your second post), but often fltk's own resizable behavior
can usually be made to work when properly employed.
For examples of custom resize behavior, see:

Keep in mind that if you override Fl_Tile::resize(), then you
probably want to do all management of children and Fl_Tile's
size/position yourself, /INSTEAD/ of calling Fl_Tile::resize().
Calling Fl_Tile::resize() will cause FLTK's automatic child
positioning to take over, which is maybe not what you want
if you want to do it all yourself.
If you want to just modify the default resize behavior,
then after you call Fl_Tile::resize(), and then adjust
things after that, be sure to call init_sizes(), to make
sure FLTK updates its cache with your new changes.
The subject of resizing has been covered quite a bit on the
newsgroup over the years, especially the older articles from
2004/2006. Try searching the forum for 'resize', 'resizable'
and 'resizing', eg:
