I have exactly the same problem. I tried a lot of different styles to apply, but none of them worked. In my opinion, the following CSS should work, but it doesn't:
Qt Code:
  1. {
  2. padding-top: 10px;
  3. padding-bottom: 10px;
  4. }
To copy to clipboard, switch view to plain text mode 
I tried also the tip from another thread (http://www.qtcentre.org/forum/f-qt-p...box-12025.html) to add the QApplication::globalStrut. This works for all Widgets, except AbstractItemView of the QComboBox.

I'm at the moment with Qt 4.3.2, and will try it today with Qt 4.4.

One solution would be to implement a custom model. But it would be so nice if I don't have to implement a custom model.
