void setError (const QString &description)
void addDependency (const QQmlDataBlob::Ptr &)
 Wait for blob to become complete or to error.
virtual void done ()
 Invoked once data has either been received or a network error occurred, and all dependencies are complete.
virtual void dependencyError (const QQmlDataBlob::Ptr &)
 Called if blob, which was previously waited for, has an error.
virtual void allDependenciesDone ()
 Called when all blobs waited for have completed.
virtual void downloadProgressChanged (qreal)
 Called when the download progress of this blob changes.
virtual void completed ()
 Invoked on the main thread sometime after done() was called on the load thread.

◆ dataReceived()

void QQmlQmldirData::dataReceived ( const SourceCodeData & )
