title: Qt Fullscreen Window hiding Win8/10 touch keyboard
body: <p>I'm currently trying to keep the Windows Touch Keyboard (<code>TabTip.exe</code>) over a <strong>fullscreen</strong> Qt QML application.</p>
  
  <p>Unfortunately, after showing (and forcing it to be on top) it's dismissed again.</p>
  
  <p>It does not matter if I start the keyboard before starting the application or while running the application in fullscreen, after Qt is gaining focus, the keyboard is behind.</p>
  
  <p>Any ideas what this could cause? Is this a Qt or Windows issue?</p>
