Hello!

Hi have this basic ui to manage data is a MySQL table:
dialog.png
The model/view approach works fine.
I'm trying now a "form" approach, using QDataWidgetMapper with the same model.
The model:
Qt Code: 
  1. QSqlTableModel *model = new QSqlTableModel(this, QSqlDatabase::database("connection1"));
  2.     model->setTable("hobby");
  3.     model->setEditStrategy(QSqlTableModel::OnFieldChange);
  4.     model->setHeaderData(0, Qt::Horizontal, "ID");
  5.     model->setHeaderData(1, Qt::Horizontal, "Nome do passatempo");
  6.     model->select();
  7.     return model;
To copy to clipboard, switch view to plain text mode 

The QDataWidgetMapper:
Qt Code: 
  1. void hobbyDialog::setupWidgetMapper()
  2. {
  3.     mapper = new QDataWidgetMapper(this);
  4.     mapper->setModel(model);
  5.     mapper->addMapping(ui->spinBoxIdHobby, 0);
  6.     mapper->addMapping(ui->lineEditNomeHobby, 1);
  7.     mapper->toFirst();
  8. ...
  9. }
To copy to clipboard, switch view to plain text mode 

Using the tableView, in order no add new record i used:
Qt Code: 
  1. void hobbyDialog::on_inserirUmRegisto_clicked()
  2. {
  3.     // Inserir um registo
  4.     view->setFocus();
  5.     int row = model->rowCount();
  6.     model->insertRows(row,1);
  7.     QModelIndex index = model->index(row, model->fieldIndex("idHobby"));
  8.     view->setCurrentIndex(index);
  9.     view->edit(index);
  10. }
To copy to clipboard, switch view to plain text mode 

Now, using the form/QDataWidgetMapper, how do i manage the add new record?
