\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.

\fn QSqlRelationalDelegate::QSqlRelationalDelegate(QObject *parent)

parent.
*/
/*!
\fn QSqlRelationalDelegate::~QSqlRelationalDelegate()

allocated resources.
