1. Don't use reinterpret_cast. Use qobject_cast, dynamic_cast, or (if you are absolutely sure what you are doing) static_cast 2. In this case use qobject_cast and check if returned value in each invocation is non-zero. Zero means that you guess about pointer type is wrong. -- Regards, Konstantin _______________________________________________ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest
