You can't assign arbitrary indexes to items in the QComboBox, the
index parameter to insertItem() is where you want to insert your new
item in an already populated QComboBox.  You can easily customize the
indexes by storing a list of pks of what you put in your QComboBox:

  def initCombo(self, records):
      self.comboItems = []
      self.combo.clear()
      for record in records:
          self.combo.insertItem(record["label"])
          self.comboItems.append(record["pk"])

  def getSelectedPK(self):
      """returns record["pk"]"""
      return self.comboItems[self.combo.currentItem()]

assuming that your record set look like this :

  records = [ {"pk":     42, 
 	       "label": "Mjolnir"}, 
              {"pk":     43, 
 	       "label": "Grayswandir"}, 
              {"pk":     44, 
 	       "label": "Excalibur"} ]
