Member Function Documentation

void QgsFeatureSelectionModel::enableSync ( bool enable )

Enables or disables synchronisation to the QgsVectorLayer When synchronisation is disabled, any selection change will be buffered inside this selection model.

When enabled, any buffered changes are communicated to the layer and the buffer is emptied. Mainly to be used for performance reasons, because selection change on the layer can cost time as it repaints the layer.

Parameters

enable The synchronisation status to set.
