Detailed Description

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:

     QTableView *view = new QTableView;
     view->setModel(model);
     view->setItemDelegate(new QSqlRelationalDelegate(view));

The Relational Table Model example (shown below) illustrates how to use QSqlRelationalDelegate in conjunction with QSqlRelationalTableModel to provide tables with foreign key support.

Member Function Documentation

QSqlRelationalDelegate::QSqlRelationalDelegate ( QObject * parent = 0 )

Constructs a QSqlRelationalDelegate object with the given parent.

QSqlRelationalDelegate::~QSqlRelationalDelegate ()

Destroys the QSqlRelationalDelegate object and frees any allocated resources.
