We've been actively discussing Tk, GTK, FOX, and wx. What happened to FLTK? It seems very lightweight (plus), already exists for ruby (plus), and supports Windows (plus). It may have few widgets? (minus), and does not support Mac (minus). I personally haven't used FLTK, but am curious if anyone here has. And if so, what do you think about it. If not, why have you chosen one of the other options? Kevin
