Catching exceptions with Qt

[Zlatomir]

Disclaimer: I'm not good with exceptions but i think you will need (to exclude the main return from the try block) something like this:

int main(int argc, char *argv[])
{
    QApplication app(argc, argv);
    //...
    int ret_val;
    try {
        ret_val = app.exec();
    }
    catch (...){
        qDebug() << "Exception";
    }
    return ret_val;
}

int main(int argc, char *argv[])
{
    QApplication app(argc, argv);
    //...
    int ret_val;
    try {
        ret_val = app.exec();
    }
    catch (...){
        qDebug() << "Exception";
    }
    return ret_val;
}

But remember that Qt doesn't throw exceptions, you will catch only yours.

Thanks, but it's still crashing.
But I think I'm getting closer to the problem, since now I'm getting a segmentation fault in QApplicationPrivate::notify_helper():

// deliver the event
bool consumed = receiver->event(e);
e->spont = false;
return consumed;

// deliver the event
bool consumed = receiver->event(e);
e->spont = false;
return consumed;

receiver is just not valid anymore here... But why is this code still executed, when an execution has been thrown?
