Detailed Description#

When editing data in an item view, editors are created and displayed by a delegate. QStyledItemDelegate , 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

bool

QComboBox

double

QDoubleSpinBox

int

int	`QSpinBox`
unsigned int
QDate	`QDateEdit`

Additional editors can be registered with the registerEditor() function.
