47 \class QSqlRelationalDelegate |
|
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: |
|
55 |
|
56 \snippet examples/sql/relationaltablemodel/relationaltablemodel.cpp 4 |
|
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. |
