title: QToolButton - Text on top of icon
body: <p>been searching the forums quite a bit..but couldnt find something reasonable. 
  I have a QToolButton and an icon. I dont want to bake the text into the icon image, I d rather have a text using btn.setText("Text").
  The problem the text is set right underneath the icon which I dont want in my case. 
  It should be on top of the icon. Is there any way to do that? 
  I guess with a custom QToolButton..could someone help me out there?</p>
  
  <pre><code>btn = QtGui.QToolButton()
  btn.setText("Text")
  icon = QtGui.QIcon()
  icon.addPixmap(os.path.join('path_to_icon.png', QtGui.QIcon.Normal, QtGui.QIcon.On)
  btn.setIcon(icon)
  </code></pre>
  
  <p>ideally:</p>
  
  <pre><code>icon.setToolButtonStyle(QtCore.Qt.ToolButtonTextOnTopIcon)
  </code></pre>
  
  <p>Is there a way to offset the text using style sheet?
  Any help is appreciated</p>
