subclass QLineEdit to have an index

[nlgootee]

Thanks for your input. This looks like something that I could use for a column of pushbuttons, but I really don't translate c++ to python very well, so I will have to work on it.

I want to thank everybody that submitted code to this discussion. We have decided to go with a different method but your expertise will not go to waste because the next part of the project absolutely needs a list and I will be able to use what I have learned here. Thanks again.
