I found the version I think I need (4.7.4) at

I have been unable to find out how to run it - so guessing I tried this.

# coding=utf8
from companyListModel import CompanyListModel
from modelTest import ModelTest
model = CompanyListModel()
tester = ModelTest(model, None)

This didn't initialise ModelTest

Traceback (most recent call last):
   File "testing.py", line 8, in <module>
     tester = ModelTest(model, None)
   File "D:\work\C-U-B\modelTest.py", line 41, in __init__
     self.connect( self.model, 
QtCore.SIGNAL("columnsAboutToBeInserted(const QtCore.QModelIndex&, int, 
int)"), self.runAllTests)
TypeError: type 'QtCore.QModelIndex' is not supported as a slot argument 

I'm way out of my depth.  (That usually means I'm about to learn 

Help needed!
