I think the problem here might be that since we're in the draw_cell()
routine, we're basically in FLTK's draw() call.
So calling redraw() might not be useful in this context.
What I did find is that if I changed the cell->redraw()
to cell->draw() instead, it worked.
Well, sort of, the correct row would turn yellow, but
the previous row that was selected didn't redraw itself
correctly, so it would probably need to be redrawn as well.
In this case, you'd probably need to make a local copy of
Fl_Table_Row, and rework it so that you do all the widget
color()ing and redraw() logic in the event handler, rather
than during actual drawing.
Hope that points you in the right direction.
Maybe what's needed is a callback() of some kind to Fl_Table_Row,
so that it provides the needed hook for this kind of thing.
Let me know what you find out..
