Detailed Description

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:

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
}
