Clients can also use the use-case-specific classes derived from QOrganizerAbstractRequest to retrieve and manipulate organizer items and collections in an asynchronous manner. However, certain functionality (e.g. backend functionality reporting) can not be accessed using the asynchronous APIs. See the \l{Qt Organizer Synchronous API}{synchronous} and \l{Qt Organizer Asynchronous API}{asynchronous} API information from the \l{Qt Organizer Overview}{organizer module} API documentation for more details. When constructing a QOrganizerManager instance, certain parameters can be given to provide more control, e.g. to specify the version of the backend it wants to construct. Note that the parameters returned when calling managerParameters() are not necessarily the same as the ones passed in, since certain parameters might be discarded or added by the backend. */ /*! \enum QOrganizerManager::Operation This enumeration describes the operation that has been done to the item or collection modified. \value Add The item / collection has been added. \value Change The item / collection has been changed. \value Remove The item / collection has been removed. */ /*! \fn QOrganizerManager::itemsModified(const QList > &itemIds); This signal is emitted at some point once the items have been modified in a datastore managed by this manager.
