title: Qt and OpenGL for game development
body: <p>I have a few questions about Qt.</p>
  
  <ol>
  <li><p>I already know that Qt and OpenGL can be used together. At the
  moment we are using GLUT at my university (for window and input
  management). I saw that Qt is able to do the same thing. <strong>Are there
  any disadvantages of using Qt instead of GLUT?</strong> <em>(performance
  wise)</em></p></li>
  <li><p>I also know that Qt can be used to build a ingame GUI. I even saw
  this 3d GUI example <a href="http://www.youtube.com/watch?v=MXS3xKV-UM0" rel="nofollow">WolfenQt</a>. So it is possible. <strong>But does it
  make sense to use Qt for an ingame GUI if you care about
  perfomance?</strong></p></li>
  </ol>
