In the case of QComboBox, "index" refers to an item's position in the combo 
box's list of items. The list of items is a list of strings.

There are a number of ways to do what you want, but they would be things like 
maintaining a separate data structure which maps items and (your) index 
values, or subclassing QComboBox to do that for you automatically. The 
implementation would depend a lot on your application.
