title: PYQT : qCombobox displaying Column "Name" but passing Column "ID"
body: <p>I've been trying very hard to get this working but so far haven't found the correct route.
  I am using pyqt, and I am querying a MySql DataBase, collecting from it a model with all the columns. Until here it's all good..</p>
  
  <p>I've created a combobox that is displaying the correct text using model.setcolumn(1)
  What I need now is for this combobox to send on "activated" the relative unique ID of this record, so I am able to create a category relatioship.</p>
  
  <p>What exactly is the best way to do this? I feel I've arrived to a dead end, any help would be appreciated.</p>
  
  <p>Best,
  Cris</p>
