QTcpSocket state always connected, even unplugging ethernet wire

Question

I have a QTcpSocket and I am reading into a loop. Each time a full packet has been read, or there has been an error, I manually check the status of the socket inside the loo

Answer 1

try this signal slot connection:

connect(this, SIGNAL(stateChanged(QAbstractSocket::SocketState)), this, SLOT(onStateChanged(QAbstractSocket::SocketState)));

at slot implementation:

void TCPWorker::onStateChanged(QAbstractSocket::SocketState socketState ){
qDebug()<< "|GSTCPWorkerThread::onStateChanged|"<

I have the same problem, but instead your problem ( always connected ), i have delay 4-5 seconds to receive disconnect signals, after unplugget ethernet wire.

Still looking solution, post answer if find.
