title: How to flip an image in Qt?
body: <p>I found <a href="http://www.youtube.com/watch?v=eZyV4f9r5m8" rel="nofollow">that video</a> on Youtube. It shows how to flip something called QML Flipable. I'm completely unfamiliar with QML so I have the following questions:</p>
  
  <p>1) Is it possible to flip an ordinary QLabel like this? If yes how do I do that?</p>
  
  <p>2) If it's not possible then how do I add that Flipable entity to my QMainWindow?</p>
  
  <p>Thanks, everyone</p>
