There's a qtRuby book available (PDF, for US$8.50) http://www.pragmaticprogrammer.com/titles/ctrubyqt/ Is anyone able to give a quick rundown on which of these toolkits will work on both Windows and OS X? It's not that clear from a number of the sites which platforms they will work on. Some (like qt) seem Linux only. I don't use Linux <ducks> but a mix os Win and OS X. Cheers, Dave
