The QGalleryItemRequest class provides a request for the properties of a single item from a gallery.
QGalleryItemRequest executes a query which returns information about the gallery item specified in itemId. The query will return an itemUrl, an itemType, resources and meta-data values for the properties listed in propertyNames.
When the request has finished and if the item could be found the valid property will be true, if not it will be false.
If the autoUpdate property is true when the request is executed it will enter an Idle state on finishing and will refresh the queried information if the item changes. If the gallery can't provide updates it will instead go immediately to the Finished state. Automatic updates can be canceled by calling cancel() on a idle request.
See also QDocumentGallery.
This property holds whether a the results of a request should be updated after a request has finished.
If this is true the request will go into the Idle state when the request has finished rather than returning to Inactive.
