Detailed DescriptionThe QOrganizerItemFetchHint class provides hints to the manager about which organizer item information needs to be retrieved. All of the hints may be ignored at the discretion of the manager, however if a manager is able to optimize retrieval of organizer items due to hints, it may do so. If a manager ignores a hint, it must retrieve the full set of data that the hint refers to. The fetch hint contains:
Important note: if certain organizer item is retrieved with fetch hint set, normal saving will result in the loss of information that is not retrieved. Partial save should be used to avoid information loss. Member Type Documentation
