Hi. I have tried upto my level how to create a Server to handle many clients, but my non of the debug msgs are working. Im presenting my simple Server client code.plz support me.

Teamstatus.h
Qt Code: 
  1. class TeamStatus : public QMainWindow {
  2.     Q_OBJECT
  3. public:
  4.     TeamStatus(QWidget *parent = 0);

  6.     void listen();
  7.      void socketdisc();
  8. protected:
  9.     void changeEvent(QEvent *e);
  10. void incomingConnection(int socketfd);
  11.  
  12. private:
