On BlackBerry 10, how can my Qt application be notified when a contact is added, deleted, or updated? Is there a contact API?
QContactManager has these 3 signals:
void QContactManager::contactsAdded ( const QList<QContactLocalId> & contactIds );
void QContactManager::contactsChanged ( const QList<QContactLocalId> & contactIds );
void QContactManager::contactsRemoved ( const QList<QContactLocalId> & contactIds );
Connect your slots to them in order to receive the notifications.
