hope this is not too far off-topic but i'm currently pre-pub reviewing the second (upcoming) edition of this book, http://www.amazon.ca/Introduction-Design-Patterns-Qt/dp/0131879057/ for pearson publishing and i was wondering if anyone out there is using a combination of C++ and Qt libs for serious production projects. if so, what do you think? any immediate advantages? any notable drawbacks? i'm just curious. rday -- ======================================================================== Robert P.
