title: Show result of Color selection in Qt?
body: <p>What is the best way to give the user feedback for a color selection?<br>
  I have a dialog with a "Select Color" push button which pops a <code>QColorDialog</code>. After the selection is made I want to show the user the color selected.<br>
  Usually I do this using a <code>QLabel</code> and changing it's background color in the palette. This method is cumbersome and I think not very portable. </p>
  
  <p>Is there a standard way of doing this?</p>
