title: How to set QCamera on label
body: <p>I've decided no to use OpenCV. I will use the QCamera class. Everything is working perfect to this moment. I can capture and save images wherever I want, but the problem is how I can set the camera to a label or graphics view?</p>
  
  <p>I mean, to see what is happening at the moment. When I make infinite loop everything crashes. Write any information you know, cause there are no examples how to do that, or I just can't see. If you can please write some source code.</p>
