- All Implemented Interfaces:
- QtJambiInterface
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 QVariant
s).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.
Additional editors can be registered with the registerEditor()
function. See also:

QItemEditorFactory
public QItemEditorFactory()
- Constructs a new item editor factory.
registerEditor
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.

createEditor()
.
createEditor
public QWidget createEditor(int type,
QWidget parent)
- Creates an editor widget with the given parent for the specified type of data, and returns it as a
QWidget
. - See also:
registerEditor()
.
valuePropertyName
public QByteArray valuePropertyName(int type)
- Returns the property name used to access data for the given type of data.
defaultFactory
public static QItemEditorFactory defaultFactory()
- Returns the default item editor factory.
- See also:
setDefaultFactory()
.
setDefaultFactory
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.
