    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.

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.

See also:
  `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.

See also:
  `defaultFactory()`.
