* @short Convenience class for getting payload parts from an Akonadi Model.
*
* This class can be used to retrieve individual payload parts from an EntityTreeModel,
* and fetch them asynchronously from the Akonadi storage if necessary.
*
* The requested part is emitted though the partFetched signal.
*
* Example:
*
* @code
*
* const QModelIndex index = view->selectionModel()->currentIndex();
*
* PartFetcher *fetcher = new PartFetcher( index, Akonadi::MessagePart::Envelope );
* connect( fetcher, SIGNAL(result(KJob*)), SLOT(fetchResult(KJob*)) );
* fetcher->start();
*
* ...
*
* MyClass::fetchResult( KJob *job )
* {
* if ( job->error() ) {
* qDebug() << job->errorText();
* return;
* }
*
* PartFetcher *fetcher = qobject_cast<PartFetcher*>( job );
*
* const Item item = fetcher->item();
* // do something with the item
* }
*
* @endcode
