Monitor Class Reference
from PyKDE4.akonadi import *
Inherits: QObject
Subclasses: Akonadi.ChangeRecorder
Namespace: Akonadi
Detailed Description
Monitors an item or collection for changes.
The Monitor emits signals if some of these objects are changed or removed or new ones are added to the Akonadi storage.
Optionally, the changed objects can be fetched automatically from the server. To enable this, see fetchCollection(), fetchItemMetaData(), fetchItemData().
@todo: distinguish between monitoring collection properties and collection content. @todo: special case for collection content counts changed

- a reference to the current item fetch scope
- See also:
- setItemFetchScope() for replacing the current item fetch scope

-
item The linked item. collection The collection the item is linked to.
- Since:
- 4.2

| Akonadi.Item | item, | |||
| Akonadi.Collection | collectionSource, | |||
| Akonadi.Collection | collectionDestination | |||
| ) |
This signal is emitted if a monitored item has been moved between two collections
- Parameters:
-
item The moved item. collectionSource The collection the item has been moved from. collectionDestination The collection the item has been moved to.
