The dataChanged Signal Not Performing as Expected

[Corny]

First I would like to apologize for a slow response, but I was sent out to the field at the end of last week so I'm just now seeing your replies.
I'd like to thank you both ChristianEhrlicher and d_stranz for the assistance


You had asked if

are you properly protecting the model against simultaneous updates with mutexes or some other thread synchronization device?

and I have not specifically included anything to insure thread synchronization. I will also re-examine the dataChanged() signal parameters and see if I can find anything similar to what you mention. I will be sure to report back what I find, if anything.

I want to thank you both again for pointing me in a direction that may provide an answer.
