create()

QgsEditorWidgetWrapper * QgsValueRelationWidgetFactory::create ( QgsVectorLayer *  vl, int  fieldIdx, QWidget *  editor, QWidget *  parent  ) const

overridevirtual

Override this in your implementation.

Create a new editor widget wrapper. Call QgsEditorWidgetRegistry::create() instead of calling this method directly.

Parameters

vl	The vector layer on which this widget will act
fieldIdx	The field index on which this widget will act
editor	An editor widget if already existent. If nullptr is provided, a new widget will be created.
parent	The parent for the wrapper class and any created widget.

Returns

A new widget wrapper

Implements QgsEditorWidgetFactory.

createSearchWidget()

QgsSearchWidgetWrapper * QgsValueRelationWidgetFactory::createSearchWidget ( QgsVectorLayer *  vl, int  fieldIdx, QWidget *  parent  ) const

overridevirtual

By default a simple QgsFilterLineEdit is returned as search widget.

Override in own factory to get something different than the default.
