    I need to have a QTimer that fires every 10s, however, the first invocation of the slot is 10s after the timer is started.

    QTimer timer;
    connect(timer, SIGNAL(timeout()), this, SLOT(timeoutFired()));
    timer.setInterval(10000);
    timer.start();
    

    Is it possible to have the timer fire immediately on calling start() and have the rest of the notifications after 10s?
