QSqlRelationalDelegate ¶

详细描述 ¶

PySide.QtSql.QSqlRelationalDelegate class provides a delegate that is used to display and edit data from a PySide.QtSql.QSqlRelationalTableModel .

Unlike the default delegate, PySide.QtSql.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 PySide.QtSql.QSqlRelationalDelegate :

view =  QTableView()
view.setModel(model)
view.setItemDelegate(QSqlRelationalDelegate(view))
										

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