QItemEditorCreatorBaseclass provides an abstract base class that must be subclassed when implementing new item editor creators. More…
QItemEditorCreatorBaseobjects are specialized widget factories that provide editor widgets for one particular
QVariantdata type. They are used by
QItemEditorFactoryto create editors for
QStyledItemDelegates. Creator bases must be registered with
An editor should provide a user property for the data it edits. QItemDelagates can then access the property using Qt’s meta-object system to set and retrieve the editing data. A property is set as the user property with the USER keyword:Q_PROPERTY(QColor color READ color WRITE setColor USER true)
If the editor does not provide a user property, it must return the name of the property from
valuePropertyName(); delegates will then use the name to access the property. If a user property exists, item delegates will not call
QStandardItemEditorCreatoris a convenience template class that can be used to register widgets without the need to subclass

- class PySide2.QtWidgets.QItemEditorCreatorBase¶
- Return type:
Returns an editor widget with the given
When implementing this function in subclasses of this class, you must construct and return new editor widgets with the parent widget specified.
- Return type:
Returns the name of the property used to get and set values in the creator’s editor widgets.
When implementing this function in subclasses, you must ensure that the editor widget’s property specified by this function can accept the type the creator is registered for. For example, a creator which constructs
QCheckBoxwidgets to edit boolean values would return the
checkableproperty name from this function, and must be registered in the item editor factory for the
Note: Since Qt 4.2 the item delegates query the user property of widgets, and only call this function if the widget has no user property. You can override this behavior by reimplementing
