title: Qt application title
body: <p>I'm developping a Qt application</p>
  
  <p>I managed to set the main window title using methode</p>
  
  <pre><code>setWindowTitle("my title");
  </code></pre>
  
  <p>however this changes the name in the application top bar, it doesn't affect the title displayed in the top bar of gnome shell (ubuntu) nor the title displayed when doing alt+tab.</p>
  
  <p>How to change it ?</p>
  
  <p>I've tried using the DEPLOYMENT.display_name variable in my .pro file</p>
