So far, given the responses in the interest mailing list, it appears that applications would break imperceptibly for notify() no longer being called in the auxiliary threads. Therefore, I'm redesigning the solution. I'm proposing then the following: 1) deprecate use of notify() in auxiliary threads, with the functionality getting removed in Qt 6 (this is a documentation change only) 2) add a way for threads to individually enable delivery past the QCoreApplication's lifetime, which implies notify() is skipped. I will add this as a private API only. 3) add new mechanisms for filtering and logging events 4) add a mechanism to catch, log and gracefully act on exceptions thrown from event handlers and slots 5) after 3 and 4 are in, deprecate overriding of notify() altogether, with the possibility removed altogether in Qt 6. Since I only need 1 & 2 for my needs, I will not implement 3-5 any time soon (or ever). Exercise left to the reader. -- Thiago Macieira - thiago.macieira (AT) intel.com Software Architect - Intel Open Source Technology Center _______________________________________________ Development mailing list Development@qt-project.org http://lists.qt-project.org/mailman/listinfo/development
