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 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.

Type	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

QItemEditorFactory

public QItemEditorFactory()

Constructs a new item editor factory.

Method Detail

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

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.

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.
