\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.
