Detailed Description

The QSqlRelationalDelegate class provides a delegate that is used to display and edit data from a QSqlRelationalTableModel.

Unlike the default delegate, QSqlRelationalDelegate provides a combobox for fields that are foreign keys into other tables. To use the class, simply call QAbstractItemView::setItemDelegate() on the view with an instance of QSqlRelationalDelegate:

        QTableView *view = new QTableView;
        view->setModel(model);
        view->setItemDelegate(new QSqlRelationalDelegate(view));

The sql/relationaltablemodel example (shown below) illustrates how to use QSqlRelationalDelegate in conjunction with QSqlRelationalTableModel to provide tables with foreigh key support.

See also QSqlRelationalTableModel and Model/View Programming.
