We had to do this for our application, and our solution was subclass
the QStyle and reimplement QStyle::subControlRect() for
SC_ComboBoxListBoxPopup to return the width of the widest item (which
happens to be the size hint of the first column in the combox's view).
If you do this, don't forget to add space for the vertical scroll bar
if it is present.

I'm not sure if this is the best way, but it is how we did it,
