#include "server.h"
 
int main(int argc, char *argv[])
{
    QCoreApplication a(argc, argv);
      MyServer server;
      server.listen(QHostAddress::Any, 4711);
    return a.exec();
}

server.cpp

Code:

---

#include <QtCore>
#include <QtNetwork>
#include "server.h"
#include "MyServerHandlerMethod.h"
 
 
MyServer::MyServer(QObject *parent):QTcpServer (parent)
{
    connect(this,SIGNAL(newConnection()),this,SLOT(MyServerHandler()));
}
 
 
void MyServer::MyServerHandler()
{
    QTcpSocket *socket = nextPendingConnection();
    if(!socket) return;
    new MyServerHandlerMethod(socket); 
 
}

---

MyServerHandlerMethod.h

Code:

---

#ifndef MYSERVERHANDLERMETHOD_H
#define MYSERVERHANDLERMETHOD_H
#include <QtCore/QString>
#include <QtNetwork>
#include <iostream>
 
using namespace std;
class MyServerHandlerMethod : public QObject
{
    Q_OBJECT
 
    public:
 
    MyServerHandlerMethod(QTcpSocket *socket, QObject *parent = 0) : QObject(parent)
    {
        connect(socket,SIGNAL(readyRead()),this,SLOT(HandlerConnection()));
        this->socket = socket;
    }
 
    }
 
 
    signals:
 
    private:
       QTcpSocket *socket;
       QString input;
 
 
       void ConnectClose()
       {
           socket->close();
           delete socket;
           deleteLater();
       }
 
    private slots:
 
       void HandlerConnection()
       {
            QByteArray data = socket->readAll();
            this->input = data; //QString input
 
            cout<< qPrintable(this->input)<<endl;
            InputHandler();
 
            ConnectClose();
 
       }
 
 
};
 
#endif // MYSERVERHANDLERMETHOD_H

in client:
main

Code:

---

#include <QtCore/QCoreApplication>
#include "client.h"
 
int main(int argc, char *argv[])
{
    QCoreApplication a(argc, argv);

    tryClient.send();
 
    return a.exec();
}

client.h

Code:

#ifndef CLIENT_H
#define CLIENT_H
 
#include <QtNetwork/QTcpSocket>
 
class client : public QObject
{
    Q_OBJECT
    public:
    void send()
    {
        const int Timeout = 5 * 1000;
        clientSocket = new QTcpSocket(this);
        clientSocket->connectToHost("localhost",4711);
        if (!clientSocket->waitForConnected(Timeout)) {
                  return;
            }
 
        clientSocket->write("ACK");
 
    }
