| 40 | \class QOrganizerManager |
| 41 | \brief The QOrganizerManager class provides an interface which allows clients with access to |
| 42 | organizer item and collection information stored in a particular backend. |
| 43 | \inmodule QtOrganizer |
| 44 | \ingroup organizer-main |
| 45 | |
| 46 | This class provides synchronous methods to retrieve and manipulate organizer item information, |
| 47 | collection information, as well as functionality reporting and error information reporting. |
| 48 | |
| 49 | Clients can also use the use-case-specific classes derived from QOrganizerAbstractRequest to |
| 50 | retrieve and manipulate organizer items and collections in an asynchronous manner. However, |
| 51 | certain functionality (e.g. backend functionality reporting) can not be accessed using the |
| 52 | asynchronous APIs. |
| 53 | |
| 54 | See the \l{Qt Organizer Synchronous API}{synchronous} and \l{Qt Organizer Asynchronous API}{asynchronous} |
| 55 | API information from the \l{Qt Organizer Overview}{organizer module} API documentation for more details. |
| 56 | |
| 57 | When constructing a QOrganizerManager instance, certain parameters can be given to provide more |
| 58 | control, e.g. to specify the version of the backend it wants to construct. Note that the parameters |
| 59 | returned when calling managerParameters() are not necessarily the same as the ones passed in, |
| 60 | since certain parameters might be discarded or added by the backend. |
