[PyQt] Signal on Selection in QTreeView

[Kevin]

Andreas,

   The problem is that my connect statement does not call the  
appropriate function.

   I've done some searching based on your recommendations, yet I have  
not been able to find a basic example I can understand.

    Could you point me to a simple example that would take a list with  
columns and can return the row number of the row that is selected?  I  
believe that I can adapt this into my app.
