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 examples/sql/relationaltablemodel/relationaltablemodel.cpp 4 The \l{sql/relationaltablemodel}{Relational Table Model} example (shown below) illustrates how to use QSqlRelationalDelegate in conjunction with QSqlRelationalTableModel to provide tables with foreign key support. \image relationaltable.png \sa QSqlRelationalTableModel, {Model/View Programming} */ /*! \fn QSqlRelationalDelegate::QSqlRelationalDelegate(QObject *parent) Constructs a QSqlRelationalDelegate object with the given \a parent. */ /*! \fn QSqlRelationalDelegate::~QSqlRelationalDelegate() Destroys the QSqlRelationalDelegate object and frees any allocated resources. */ /*! \fn QWidget *QSqlRelationalDelegate::createEditor(QWidget *parent, const QStyleOptionViewItem &option, const QModelIndex &index) const \reimp */ /*! \fn void QSqlRelationalDelegate::setEditorData(QWidget *editor, const QModelIndex &index) const \reimp */ /*! \fn void QSqlRelationalDelegate::setModelData(QWidget *editor, QAbstractItemModel *model, const QModelIndex &index) const \reimp */ QT_END_NAMESPACE
