I have a thread and a tcpSocket. The tcpSocket is declared in my "x.h" class.

At some point I want to use this tcpSocket, but I get this message:

ASSERT failure in QObject::QObject(): "Cannot create children for a parent that is in a different thread.", file kernel/qobject.cpp, line 599

This is the code where I create my tcpSocket:
Qt Code: 
  1. void Client :: run()
  2. {
  3.      cout << "void Client :: run()\n";
  4.      tcpSocket = new QTcpSocket();    
  5.      if(!tcpSocket->setSocketDescriptor(socketDescriptor))
  6.      {
  7.           cout << "Error - tcpSocket descriptor\n";
  8.           return;
  9.      }
  10.      connect(tcpSocket, SIGNAL(readyRead()), this, SLOT(readData()));
  11.      connect(tcpSocket, SIGNAL(disconnected()), this, SLOT(clientDisconnected()));
  12.      exec();
  13. }

This is the code where I want my tcpSocket to write to another computer:
Qt Code: 
  1. void Client :: loginResponse(bool accepted, QString *userName, QByteArray *messageOut)
  2. {
  3.      if(accepted==true)
  4.      {
  5.           server->addClient(*userName, this);
  6.           clientLogged = true;
  7.           tcpSocket->write("hello\n");
  8.      }
  9. }

How can i refer to the tcpSocket that was instantiated in the run() ?
