QSqlRelationalDelegate Class

Detailed Description

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:

     std::unique_ptr<QTableView> view{new QTableView};
     view->setModel(model);
     view->setItemDelegate(new QSqlRelationalDelegate(view.get()));

The Relational Table Model example (shown below) illustrates how to use QSqlRelationalDelegate in conjunction with QSqlRelationalTableModel to provide tables with foreign key support.
