This is probably the wrong way to approach this problem. It might be useful if you could describe what you are actually trying to achieve, rather than describing (in considerable detail, I must say!) the problems you encountered with this approach. It is likely that, if we know where you are going to, we might be able to suggest other ways to get there that will help you! _______________________________________________ fltk mailing list [email protected] http://lists.easysw.com/mailman/listinfo/fltk
