Re: QsqlQueryModel Subclass
The better way is make use of a custom proxy model, and not disturb the QSqlQueryModel. Moreover implementing QSqlQueryModel::setData() may not be practical as you don't know how the QSqlQueryModel stores the data internally.
The proxy model will add the extra column.
When you know how to do it then you may do it wrong.
When you don't know how to do it then it is not that you may do it wrong but you may not do it right.
