title: touch events in linux using Qt
body: <p>I am trying to program touch events in linux using Qt. My touch screen works, however when I touch the screen I get mouse events rather than touch events. The mouse cursor moves to where I touch the screen. I don't know if it is a Qt problem or something that happens at the OS level.</p>
  <p>I am using Qt 5.4.0 on Debian Jessie.</p>
