title: How to receive touch event in Qt?
body: <p>Is there any way to receive when the screen is touched in Qt. I need to reset a counter to 0, whenever the touch screen is touched.</p>
  
  <p>I'm having the function <code>systemIdleControl</code> which resets the counter to zero. So when I touch the touch screen it should call the <code>systemIdleControl</code>.</p>
