QtSparqlTracker extension

An add-on package for QtSparql, containing tracker-specific functionalities.

GraphUpdate signals

Tracker sends a GraphUpdate signal over D-Bus when the content of the data store changes and the change involves certain pre-defined ontology classes.

TrackerChangeNotifier wraps around the GraphUpdated signal in a straightforward way.

Sync

Tracker::syncTracker() is a wrapper around the Tracker D-Bus function of the same name. It forces Tracker to flush its data to the database.
