A simple TCP Server - the old way to do it

/* Extract from server.h */

class Server : public QTcpServer
{
    Q_OBJECT
public:
    Server(QObject *parent = 0);
    virtual ~Server() { }
private slots:
    void handleConnection();
    void handleRead();
};

/* Extract from server.cpp */

Server::Server(QObject *parent) : QTcpServer(parent)
{
    listen(QHostAddress::Any, 5555);
    connect(this, SIGNAL(newConnection()), SLOT(handleConnection()));
}
void Server::handleConnection()
{
    QTcpSocket *socket = nextPendingConnection();
    connect(socket, SIGNAL(readyRead()), SLOT(handleRead()));
}
void Server::handleRead()
{
    char buffer[1024];
    buffer[qobject_cast<QTCPSocket *>(QObject::sender())->read(buffer, 1023)] = 0;
    std::cout << buffer;
}
