Yes: just catch them before letting them come back to any Qt function. You should treat all your slots and event handlers as "noexcept" (you may even want to mark them as such). > I want this for "debug purposes" only.

If an exception escapes, BadThings™ will happen. Your application may crash before getting to notify(), or abort by std::terminate(). Or it may cause data corruption. -- Thiago Macieira - thiago.macieira (AT) intel.com Software Architect - Intel System Software Products _______________________________________________ Interest mailing list Interest@qt-project.org https://lists.qt-project.org/listinfo/interest
