This element will load a relation editor onto the form.
void setNmRelationId(const QVariant &nmRelationId=QVariant())
Sets nmRelationId for the relation id of the second relation involved in an N:M relation.
bool init(QgsRelationManager *relManager)
Initializes the relation from the id.
void setRelationWidgetTypeId(const QString &relationWidgetTypeId)
Sets the relation widget type.
QgsAttributeEditorElement * clone(QgsAttributeEditorElement *parent) const override
Returns a clone of this element.
QVariantMap relationEditorConfiguration() const
Returns the relation editor widget configuration.
void setForceSuppressFormPopup(bool forceSuppressFormPopup)
