title: How to center text in QComboBox?
body: <p>I've tried using QComboBox's model() with no apparent success. I wonder if it would be possible to align a text at the center of QCombobox. Aside from text alignment it seems the item's font is not effected by changing its PointSize.... </p>
  
  <pre><code>    combo=QtGui.QComboBox()
      comboModel=combo.model()
  
      for name in ['one','two','three']:
          item = QtGui.QStandardItem(name)
          itemFont = item.font()
          itemFont.setPointSize(8)
          item.setFont(itemFont)
          # item.setAlignment(QtCore.Qt.AlignCenter)
          comboModel.appendRow(item)
  </code></pre>
