|
---|
| 48 | \brief The QSqlRelationalDelegate class provides a delegate that is used to
|
---|
| 49 | display and edit data from a QSqlRelationalTableModel.
|
---|
| 50 |
|
---|
| 51 | Unlike the default delegate, QSqlRelationalDelegate provides a
|
---|
| 52 | combobox for fields that are foreign keys into other tables. To
|
---|
| 53 | use the class, simply call QAbstractItemView::setItemDelegate()
|
---|
| 54 | on the view with an instance of QSqlRelationalDelegate:

|
---|
| 57 |
|
---|
| 58 | The \l{sql/relationaltablemodel}{Relational Table Model} example
|
---|
| 59 | (shown below) illustrates how to use QSqlRelationalDelegate in
|
---|
| 60 | conjunction with QSqlRelationalTableModel to provide tables with
|
---|
| 61 | foreign key support.
