Detailed Description

The QOrganizerItemChangeSet class provides a simple API to simplify the emission of state-change signals from QOrganizerManagerEngine implementations.

This class can be utilised by backend implementations to ensure correct emission of the QOrganizerManagerEngine::dataChanged(), QOrganizerManagerEngine::itemsAdded(), QOrganizerManagerEngine::itemsChanged() and QOrganizerManagerEngine::itemsRemoved().

See also QOrganizerManagerEngine.
