I want a table view with 2 columns:
  • one simple cell
  • one qcombobox

I set up the QCombobox delegate and two different views just to be sure that the database gets the values the user inserts.

The user inserts a string in the empty cell and a value from the combobox.
Then he pushes the addNewRow button to insert a new record.

I am about to create a button which is going to send the database values (that the user inserted) into a txt file.

My question is,
Do I need to implement a QDataWidgetMapper?

Qt Code: 
  1. MyDialog::MyDialog(QWidget *parent)
  2.     : QWidget(parent)
  3. {
  4.  
  5.     model = new QStandardItemModel(1, 2);
  6.     tableView = new QTableView(this);
  7.     tableView->setModel(model);
  8.  
  9.     delegate = new ComboBoxDelegate;
  10.     tableView->setItemDelegateForColumn(1,delegate);
  11.  
  12.  
  13.     view2 = new QTableView(this);
  14.     view2->setModel(model);
  15.     view2->setItemDelegateForColumn(1,delegate);
  16.  
  17.     for ( int i = 0; i < model->rowCount(); ++i )
  18.         tableView->openPersistentEditor( model->index(i, 1, QModelIndex()) );
  19.  
  20.     QLineEdit* le = new QLineEdit();
  21.  
  22.     QPushButton *newRowBtn =  new QPushButton;
  23.     newRowBtn->setText("add new row");
  24.     connect(newRowBtn,SIGNAL(clicked()),this,SLOT(addNewRow()));
  25.  
  26.  
  27.     vboxlayout = new QVBoxLayout(this);
  28.     vboxlayout->addWidget(tableView);
  29.     vboxlayout->addWidget(view2);
  30.     vboxlayout->addWidget(new QLabel("Vorgang2"));
  31.     vboxlayout->addWidget(le);
  32.     vboxlayout->addWidget(newRowBtn);
  33.     setLayout(vboxlayout);
  34. }
  35.  
  36.  
  37.  
  38. void  MyDialog::addNewRow()
  39. {
  40.  
  41.     QModelIndex index;
  42.     int row = model->rowCount();
  43.     model->insertRow(row);
  44.     index = model->index(row, 0);
  45.     tableView->setCurrentIndex(index);
  46.     tableView->edit(index);
  47.     tableView->openPersistentEditor( model->index(row, 1, QModelIndex()) );
  48.  
  49. }
