Is something like this what you were talking about?

Qt Code: 
  1. //.h
  2. struct struct_ClientSocket
  3. {
  4. 	QTcpSocket *pClientSocket;
  5. 	QString str_ClientAddress;
  6. 	int nPort;
  7. };
  8.  
  9. private:
  10. 	QList<struct_ClientSocket> m_lst_pClientSockets;
  11.  
  12. private slots:
  13. 	void SetIncomingSocket();
  14. 	void OnSocketDestroyed();
  15. 	void ReadInputData();
  16.  
  17. //.cpp
  18. void CKeyboardLogAdmin::SetIncomingSocket()
  19. {
  20. 	QStringList str_lst_Name;
  21. 	QTcpSocket *tempSocket = pTcpServer->nextPendingConnection();
  22. 	struct_ClientSocket temp_struct_ClientSocket;
  23. 	temp_struct_ClientSocket.pClientSocket = tempSocket;
  24. 	temp_struct_ClientSocket.str_ClientAddress = tempSocket->peerAddress().toString();
  25. 	temp_struct_ClientSocket.nPort = tempSocket->peerPort();
  26. 	connect(tempSocket, SIGNAL(destroyed(QObject*)), this, SLOT(OnSocketDestroyed(QObject*)));
  27. 	connect(tempSocket, SIGNAL(disconnected()), tempSocket, SLOT(deleteLater()));
  28. 	connect(tempSocket, SIGNAL(readyRead()), this, SLOT(ReadInputData()));
  29. 	m_lst_pClientSockets.append(temp_struct_ClientSocket);
