readyRead in QWebSocket

[Mikeeeeee]

Hi!
In QTcpSocket work signal readyRead , but in QWebSocket this signal not work. How to replace this signal?

[J.Hilk]

QWebSocket directly derives from QTcpSocket. -> ReadyRead does work

@j-hilk said in readyRead in QWebSocket:

QWebSocket directly derives from QTcpSocket

No per online documentation

Inherits: QObject

ReadyRead does work

Have you really tried it?
Again, from online documentation there's no signal readyRead() at all...

per source code it does

QWebSocketPrivate::QWebSocketPrivate(QTcpSocket *pTcpSocket, QWebSocketProtocol::Version version,
                                     QWebSocket *pWebSocket) :
    QObjectPrivate(),
    q_ptr(pWebSocket),
    m_pSocket(pTcpSocket),
    m_errorString(pTcpSocket->errorString()),
    m_version(version),
    m_resourceName(),
    m_request(),
    m_origin(),
    m_protocol(),
    m_extension(),
    m_socketState(pTcpSocket->state()),
    m_pauseMode(pTcpSocket->pauseMode()),
    m_readBufferSize(pTcpSocket->readBufferSize()),
    m_key(),
    m_mustMask(true),
    m_isClosingHandshakeSent(false),
    m_isClosingHandshakeReceived(false),
    m_closeCode(QWebSocketProtocol::CloseCodeNormal),
    m_closeReason(),
    m_pingTimer(),
    m_dataProcessor(),
    m_configuration(),
    m_pMaskGenerator(&m_defaultMaskGenerator),
    m_defaultMaskGenerator(),
    m_handshakeState(NothingDoneState)
{
}

It's from the private web socket class part so it may change in the future, but currently it is

and no, I haven't tried.
No example at hand right now

But I concur, going through the publicly available functions and signals, readyRead is indeed not forwarded. Interesting 🤔

@mikeeeeee you may want to look at this example.

You may need to think using a slightly different approach, with signals like connected(), disconnected(), binaryMessageReceived(), textMessageReceived() and so on.

@j-hilk said in readyRead in QWebSocket:

per source code it does

No, it does not

The source code snippet you posted clearly shows that QWebSocketPrivate class (the underlying implementation for QWebSocket) has QTcpSocket as a member, but it doesn't derive from it.

QWebSocketPrivate::QWebSocketPrivate(QTcpSocket *pTcpSocket, QWebSocketProtocol::Version version, QWebSocket *pWebSocket) :
    QObjectPrivate(),
...
    m_pSocket(pTcpSocket),
...

And keeping on looking at source code, you'll find out that the QTcpSocket::readyRead() signal is "hidden" in the QWebsocketPrivate class, as it is handled internally

    QObjectPrivate::connect(pTcpSocket, &QAbstractSocket::readyRead, this, &QWebSocketPrivate::processData, Qt::QueuedConnection);

jup, I agree, my initial statement was incorrect
