changeset_started


Description:

public virtual signal void changeset_started ()

Connect to this signal to be notified when a changeset that can contain multiple row additions / changes / removals is about to be committed to the model.

Note that not all model implementations use the changeset approach and you might still get a row change signal outside of changeset-started and changeset-finished signals. It also isn't guaranteed that a changeset would always be non-empty.
