All Implemented Interfaces:

public class QItemEditorFactory
extends QtJambiObject

The QItemEditorFactory class provides widgets for editing item data in views and delegates. When editing data in an item view, editors are created and displayed by a delegate. QItemDelegate, which is the delegate by default installed on Qt's item views, uses a QItemEditorFactory to create editors for it. A default unique instance provided by QItemEditorFactory is used by all item delegates. If you set a new default factory with setDefaultFactory(), the new factory will be used by existing and new delegates.

A factory keeps a collection of QItemEditorCreatorBase instances, which are specialized editors that produce editors for one particular QVariant data type (All Qt models store their data in QVariants).

Standard Editing Widgets

The standard factory implementation provides editors for a variety of data types. These are created whenever a delegate needs to provide an editor for data supplied by a model. The following table shows the relationship between types and the standard editors provided.
Editor Widget
bool QComboBox
double QDoubleSpinBox
int QSpinBox
unsigned int
QDate QDateEdit
QDateTime QDateTimeEdit
QPixmap QLabel
QString QLineEdit
QTime QTimeEdit
Additional editors can be registered with the
registerEditor() function.

Constructor Detail


public QItemEditorFactory()
Constructs a new item editor factory.

Method Detail


public final void registerEditor(int type,
                                 QItemEditorCreatorBase creator)
Registers an item editor creator specified by creator for the given type of data.

Note: The factory takes ownership of the item editor creator and will destroy it if a new creator for the same type is registered later.

public QByteArray valuePropertyName(int type)
Returns the property name used to access data for the given type of data.


public static QItemEditorFactory defaultFactory()
Returns the default item editor factory.

See also:


public static void setDefaultFactory(QItemEditorFactory factory)
Sets the default item editor factory to the given factory. Both new and existing delegates will use the new factory.
