Your assumption is correct. We don't use glib on Windows. We don't even search for it. > 2, There is a lack of good examples regarding Qt and 3rd party glib > implementations for which I believe the class was designed for. There are less than 10 people in the world that need to implement event dispatchers, including the people who wrote the ones in Qt. That's why it's not very documented: too much effort for too little gain. It's best just to read the code for the existing glib and Windows dispatchers and ask questions here and in dev@.

That is, QObject::startTimer calls this function: int QAbstractEventDispatcher::registerTimer(int interval, Qt::TimerType timerType, QObject *object) { int id = QAbstractEventDispatcherPrivate::allocateTimerId(); registerTimer(id, interval, timerType, object); return id; } [Qt 5 code; in Qt 4, there's no timer type] -- Thiago Macieira - thiago.macieira (AT) intel.com Software Architect - Intel Open Source Technology Center
