ThreadID does not change

[Bernie]

Hi,
at the moment I try to program a TcpServer and i would like to thread the socket.
So my code looks like this:

void Server::incomingConnection(int socketId)
{
	socket = new ClientSocket;
	socket->setSocketDescriptor(socketId);
 
	QThread *socketThread = new QThread;
 
	socket->moveToThread(socketThread);
	socketThread->start();
 
}

void Server::incomingConnection(int socketId)
{
	socket = new ClientSocket;
	socket->setSocketDescriptor(socketId);

	QThread *socketThread = new QThread;

	socket->moveToThread(socketThread);
	socketThread->start();

}

To copy to clipboard, switch view to plain text mode 

With this code I expected two threads. One main thread and another for my ClientSocket. But using

qDebug() << QThread::currentThreadId;

qDebug() << QThread::currentThreadId;

To copy to clipboard, switch view to plain text mode 

returns always the same ThreadID (in Server and ClientSocket class).

What am I doing wrong? Or am I using currentThreadId wrong?
Thanks for your help.
