title: Touch doesnt work with Qt5.1.1 when used with Wayland & qtwayland
body: <p>I want to make Qt 5.1.1 touch example application work with qtwayland module.</p>
  
  <p>I get the window on display, and also I get the touch traces from Weston. I see qtwayland is also getting triggered with the callback function that is registered for touch-up, touch-down, touch-motion.</p>
  
  <p>But, QT doesn't invoke the QPushButton handler in QT application.</p>
  
  <p>Connect API I am using as below:
  connect(ui->b_audio, SIGNAL(pressed()), this, SLOT(on_b_audio_clicked()));</p>
  
  <p>Any clue why this could happen? Please suggest probable problems so that I can explore and debug.</p>
  
  <p>Thanks in Advance.
  Bhushan.</p>
