QWebSocket sendTextMessage - Thread error QSocketNotifier cannot be enabled

didu

Hello,

I have create a QThread that handle my QWebSocket communcation.
Everything seems to work fine but when I want to user "sendTextMessage" I get this error:
QSocketNotifier: Socket notifiers cannot be enabled or disabled from another thread

I do not really understand why I get it because it seems to me that it is the same thread that have created the QWebsocket and the one called during onConnected.

class WebSocketClient : public QThread
{
    Q_OBJECT
public:
    explicit WebSocketClient(QUrl url, QObject *parent = Q_NULLPTR);

    virtual void run()
{
    qDebug() << "New Thread started";

    m_webSocket = new QWebSocket();
    connect(m_webSocket, SIGNAL(connected()), this, SLOT(onConnected()));
    connect(m_webSocket, SIGNAL(disconnected()), this, SLOT(onDisconnected()));

    m_webSocket->open(m_url);
    exec();
}

private Q_SLOTS:
    void onConnected()
{
    qDebug() << QTime::currentTime().toString("hh:mm:ss.zzz") << m_webSocket->requestUrl() << " Connected.";

    connect(m_webSocket, &QWebSocket::textMessageReceived,
            this, &WebSocketClient::onTextMessageReceived);

    m_webSocket->sendTextMessage("test");
    //QSocketNotifier: Socket notifiers cannot be enabled or disabled from another thread
}
    void onDisconnected()
{
    qDebug() << QTime::currentTime().toString("hh:mm:ss.zzz") << "onDisconnected:" << m_webSocket->requestUrl() << m_webSocket->errorString();
    disconnect(m_webSocket, &QWebSocket::textMessageReceived,
               this, &WebSocketClient::onTextMessageReceived);

    m_webSocket->deleteLater();
    exit(0);
}

private:
    QWebSocket* m_webSocket;
    QUrl m_url;
};

Does someones have a idea :( ?

I found that the "run" function is called by the new thread.
But onConnected and onDisconnected are called by the main thread ! (the thread that have created the WebSocketClient instance)

It looks like I have to review how the signal and slots are connected.
What is the appropriate way to make the signal stay in the new thread ?

Edit: Fixed with:

WebSocketClient mySocket;
mySocket->moveToThread(mySocket);

onConnected and on Disconnected was properly called by the new thread.
