Qt incomingConnections not being called

I have compiled a Qt Travel Planner Example which uses QTcpSocket

both QTcpServer

to create a client and a server.

The problem is the server slot is incomingConnection()

not being called. Although the client is successfully connecting to the server. Therefore, the socket signal is readyRead()

never emitted and no data is returned by the client.

tripserver.cpp

TripServer::TripServer(QObject *parent)
    : QTcpServer(parent)
{
}


void TripServer::incomingConnection(int socketId)
{
    qDebug() << "Incoming Connection";
    ClientSocket *socket = new ClientSocket(this);
    socket->setSocketDescriptor(socketId);
}

      

        
        
        
      

    

If I add a newConnection () slot, it gets called. So what's going on?
