TCP server, show only the selected clients messages



  • I am developing a simple tcp server with qt. There is no problem with that. But the problem is, i have listed every connected client in a listbox and i want to see the incoming data only from the selected client from the listbox but i can only see the last connected client's messages. here is the code, this is the constructor part
    @
    server = new QTcpServer();
    client = new QTcpSocket();
    connect(server, SIGNAL(newConnection()),this, SLOT(acceptConnection()));
    server->listen(QHostAddress::Any, ui->txtPort->text().toInt(bool(),10));
    if(server->isListening())
    {
    ui->statusBar->showMessage("Server Started..");
    }
    else
    {
    ui->statusBar->showMessage("Server Not Started..");
    }

    connect(client,SIGNAL(disconnected()),this,SLOT(client_disconnected()));
    
    connect(ui->listWidget,SIGNAL(clicked(QModelIndex)),this,SLOT(selected_client()));
    

    @

    here is acceptConnection() part

    @
    client = server->nextPendingConnection();

    ui->listWidget->insertItem(client_count,client->peerAddress().toString());
    client_count++;
    

    @

    and this is the listWidget item's selected item event

    @
    ui->txtRead->clear();
    selected_client_index = ui->listWidget->currentIndex().row();
    connect(client, SIGNAL(readyRead()),this, SLOT(startRead()));
    @

    and lastly the startRead() part

    @
    char buffer[1024] = {0};
    client->read(buffer, client->bytesAvailable());
    qDebug() << buffer;
    ui->txtRead->insertPlainText(buffer);
    @

    How can i select the specific client and show its messages ?
    Thanks in advance.



  • You should have a list of clients instances not only one.



  • yes i have created @QList<QTcpSocket*> client_list;@ and append every client in it.
