Resets the model to either an empty feature list or one that contains only the selected features.

Parameters:

• keepSelected if set to TRUE, selected features will be kept when resetting the model.

---

Q_INVOKABLE bool QfMultiFeatureListModel::deleteFeature (
    QgsVectorLayer * layer,
    QgsFeatureId fid
) 

Deletes a feature from a vector layer

Parameters:
