45 \class QSqlRelationalDelegate
46 \inmodule QtSql
47 \brief The QSqlRelationalDelegate class provides a delegate that is used to
48 display and edit data from a QSqlRelationalTableModel.
49
50 Unlike the default delegate, QSqlRelationalDelegate provides a
51 combobox for fields that are foreign keys into other tables. To
52 use the class, simply call QAbstractItemView::setItemDelegate()
53 on the view with an instance of QSqlRelationalDelegate:

56
57 The \l{relationaltablemodel}{Relational Table Model} example
58 (shown below) illustrates how to use QSqlRelationalDelegate in
59 conjunction with QSqlRelationalTableModel to provide tables with
60 foreign key support.
