The rule is: do not let exceptions propagate through Qt code. If you call qt_metacall directly (or, better, the static version), then the code is compiled with exceptions if they were enabled by the user code. In that case, it's safe to throw exceptions (provided that the class of the return type is also exception-safe). If you use the invokeMethod() machinery, it's not thread-safe today and not meant to be. -- Thiago Macieira - thiago.macieira (AT) intel.com Software Architect - Intel Open Source Technology Center
