Hello, i am trying to make a small database redactor with QDataWidgetMapper as edit field for data and qtableview. Pressing button "add new parameter" must add a new record to model with current data from QDataWidgetMapper. Currentrly a managed to add an empty record in the end af model. How must i do it and what is the best way?
Adding some source code with model and mapper:

Qt Code: 
  1. filterModel = new QSortFilterProxyModel;
  2.         filterModel->setSourceModel(modelt);
  3.         filterModel->setFilterKeyColumn(2);
  4.         mapper = new QDataWidgetMapper(this);
  5.         mapper->setModel(filterModel);
  6.         mapper->addMapping(le1, 2);
  7.         mapper->addMapping(le2, 1);
  8.         mapper->addMapping(le3, 3);
  9.         mapper->addMapping(le4, 5);
  10.         mapper->addMapping(le5, 6);
  11.         mapper->setSubmitPolicy(QDataWidgetMapper::ManualSubmit);
  12.         ......
  13.         QPushButton* pcmd3 = new QPushButton("Add new parameter");
  14.         pcmd3->setIcon(QIcon(":/icons/16x16/actions/add.png"));
  15.         connect(pcmd3, SIGNAL(clicked()), this, SLOT(insertRow()));
To copy to clipboard, switch view to plain text mode 
and slot:
Qt Code: 
  1. void MainWindow::insertRow()
  2.         {
  3.         filterModel->insertRow(filterModel->rowCount());
  4.         mapper->toLast();
  5.         mapper->submit();
  6.         }
