Exemplos de decoderError em C++ (Cpp)

Exemplo n.º 1

// Called in loading thread
// Essentially a second ctor, doesn't need locks (?)
void QSample::load()
{
    Q_ASSERT(QThread::currentThread()->objectName() == "QSampleCache::LoadingThread");
#ifdef QT_SAMPLECACHE_DEBUG
    qDebug() << "QSample: load [" << m_url << "]";
#endif
    m_stream = m_parent->networkAccessManager().get(QNetworkRequest(m_url));
    connect(m_stream, SIGNAL(error(QNetworkReply::NetworkError)), SLOT(decoderError()));
    m_waveDecoder = new QWaveDecoder(m_stream);
    connect(m_waveDecoder, SIGNAL(formatKnown()), SLOT(decoderReady()));
    connect(m_waveDecoder, SIGNAL(invalidFormat()), SLOT(decoderError()));
    connect(m_waveDecoder, SIGNAL(readyRead()), SLOT(readSample()));
