Color a row - QSqlRelationalTableModel or QSqlQueryModel

[AKG]

And i can't belive that you are insinutating and assuming that im stupid.... but if you need to do that, we would both be better off if you don't answer me at all.
I was trying to say - why not the other example where const was used - not why you did not use const on a value that is receiving a value.

I was clear in the start that english is not my language and that im spendign lots of time just translating trying to understand the english of what is explained.

Even in the first message i say i have code that is woriking, but it is to big many lines of code.

And this discussion is ONLY about speed, as you can see all the code is painting the row yellow so that is clearly not what this is about but to make if faster, because my view is very slow because so many is loaded and going on.
When is said dont work, i mean it is to slow
