Why doesn't the signal fire in Qt?

Question

Qt

In the stream, I create a socket and make a connection:

mTcpSocket = new QTcpSocket;
mTcpSocket->setSocketDescriptor(mSockD);
connect(mTcpSocket, &QTcpSocket::readyRead, this, &Listener::SlotMessageAccepted);

Those. when data is received, a method is called to process it.
The problem is that when the server sends data, this thing doesn't work...
But the data definitely goes to the socket!
When the above code I wrote this:

QByteArray Block;
_sock->waitForReadyRead();
while (_sock->bytesAvailable() > 0)
    Block.append(_sock->readAll());

Data was received and recorded in Block. Those. the problem, as I understand it, is not in the delivery of data, but in the connection.
But how to fix the problem?

Answer 1

I figured out what the problem is. The problem is that all incoming data goes to the socket, which is in the main thread, and nothing just reaches the socket in the other thread.
Tell me, is it possible to somehow tell sockets to either only read or only send data?
