howto add new row to QSqlTableModel with QDataWidgetMapper

[scarleton]

Phase one was creating the form to edit an existing row using QSqlTableModel/QDataWidgetMapper. I figured that out, and in the process, learned a lot. After digging around a bit, I cannot figure out how to go about adding a whole new row.

As I said in the other post, the final three lines of the constructor are currently:

_model->setFilter(QString("PARISHNER_ID = %1").arg(parishionerId));
    _model->select();
    _mapper->toFirst();

_model->setFilter(QString("PARISHNER_ID = %1").arg(parishionerId));
    _model->select();
    _mapper->toFirst();

To copy to clipboard, switch view to plain text mode 

How do I go about getting the model to a row that does not exist as of yet? so a new parishner can be added?
