[править] Подробное описание

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).

[править] 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.

[править]

void QItemEditorFactory::registerEditor ( QVariant::Type type, QItemEditorCreatorBase * creator )

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().

[править]

void QItemEditorFactory::setDefaultFactory ( QItemEditorFactory * factory ) [static]

Sets the default item editor factory to the given factory. Both new and existing delegates will use the new factory.
