| \class QSqlRelationalDelegate |
| \inmodule QtSql |
| \brief 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: |
| |
| \snippet relationaltablemodel/relationaltablemodel.cpp 4 |
| |
| The \l{relationaltablemodel}{Relational Table Model} example |
| (shown below) illustrates how to use QSqlRelationalDelegate in |
| conjunction with QSqlRelationalTableModel to provide tables with |
| foreign key support. |
