A socket descriptor is not a QAbstractSocket. It's like comparing a byte to a 
QString.

First, I have to question why you need a thread at all. What kind of 
operations do you plan on doing that require a thread?

UDP has no "accept". So I will assume you meant TCP servers.

void SomeObject::slotNewConnection()
{
	QTcpSocket *clientSocket = listener->nextPendingConnection();
	ClientHandler *handler = new ClientHandler;
	clientSocket->moveToThread(handler);
	handler->start();
}

void ClientHandler::run()
{
	SomeOtherObject obj;
	obj.connect(clientSocket, SIGNAL(readyRead()), SLOT(slotReadyRead()));
	exec();
}

void SomeOtherObject::slotReadyRead()
{
	QByteArray msg = clientSocket->readAll();
}

Note that the threading bits in my code are completely unnecessary.
