title: PyQt4 - QTableView - How to loop over QTableView
body: <p>I tried to find an example in python where I can loop over model elements of a QTableView and print the entire row.
  I have found how to loop over selected rows but nothing when rows are not selected.</p>
  
  <p>Can someone help me? No need to tell me how to create the model and how to apply it to the QTableModel. I am only interested how to iterate over the rows.</p>
