Multiple QtimerEvent handling

qt_ankit_developer

Dear sir,
I have used single Q TimerEvent to call a timer slot continuously in given specific time. but in My application I have to call multiple Q timer events from a single push button .
so please help me for firing of multiple QTimerevent .
and how to kill by using their QTimerId of every Q timer event;

do you create the timer events manually?! o.O
If so, why??

@J.Hilk said in Q timer Event with timer id:

@qt_ankit_developer
even so @sierdzio is correct, a QTimer instance would be easier. Here is how you would do it via QTimerEvent:

void myClass::startMyTimerEvent()
{
    if (m_timerId == -1)
        m_timerId = startTimer(m_Timeout);
}
 
void myClass:: stopMyTimerEvent()
{
    if (m_timerId != -1)
        killTimer(m_timerId);
    m_timerId = -1;
}

void myClass::timerEvent(QTimerEvent *event)
{
   if(event->timerId() == m_timerId) {
       //do Stufff
       ....
      callMyFunction();
   }
}

instead of a single member variable, m_timerId use a QVector or QList of ints to store your ID's.

I feel you should use the QTimer and be happy. You can refer my GIT see the example. timeEvent handling requires good boilerplate code.
