Yes, that's right. But I forgot to mention in my post that I need to use 
ListBoxItems. Why? I need a value associated to each item of the combo, just 
like 'value' when using the tag <SELECT> in HTML. Do you know?

So, I thought that I could create a new class which inherited from ListBoxItem 
(let's call ListBoxItemExtended), adding this value. Then, putting some 
ListBoxItemExtended objects into a QListBox and getting this list into de 
QComboBox could do the trick.

Yes, I tried that too but it didn't work.

Thank you for your time and your help.
