title: Qt multiple mouse clicks at the same time
body: <p>I have an application that has two buttons, and I want to detect when both buttons are pressed at the same time. </p>
  
  <p>I have installed another mouse on my Ubuntu 10.04 computer and enabled the second pointer following these steps: <a href="http://ao2.it/en/blog/2010/01/19/poor-mans-multi-touch-using-multiple-mice-xorg" rel="nofollow">http://ao2.it/en/blog/2010/01/19/poor-mans-multi-touch-using-multiple-mice-xorg</a>
  I've executed the example there (demo-paint) and I can perform simultaneous independent drawings with each mouse.</p>
  
  <p>But on my Qt application, if I keep Button1 pressed with mouse1 and move mouse2 and press button2, button1 is immediately unpressed, so I can't keep both pressed at the same time.</p>
  
  <p>Is there anyway to allow both buttons to keep pressed at the same time?</p>
