// Note:
//   One might think it's a good idea for this QRange class to use a RangeCombo.
//   But it violates the principles of object oriented programming.
//   That's because a RangeCombo requires two Combos to keep them in sync.
//   However, as a private member, Combo is hidden by QSliderEdit, and
//   QRange simply cannot access Combos.
