我的专属QQ 功能篇 （一）

  ✿写在开头     

   之前只总结了透明、无边框、可移动窗口的UI处理，为了给某位同学提供些学习资料，我再总结些功能要点。

   原则：少说废话，多上代码。

 

  ✿登录窗口

    登录操作TcpSocket，如果你非要问我为什么不是UDP Socket ，我只能说因为tcp可靠。

    

 

     ❀登录

      在确保设置IP端口后，通过QDataStream 写 QIODevice

     

void login::on_loginButton()
{
         usrname = ui->usrnamelineEdit->text().trimmed();
         password = ui->passwordlineEdit->text().trimmed();


        QRegExp rx("^[1-9]{1,2}[0-9]{4,7}{1}quot;);
        rx.setPatternSyntax(QRegExp::RegExp);
        if (!rx.exactMatch(usrname))
        {
            QMessageBox::warning(NULL, tr("提示"), tr("请输入QQ号."));
        }
        else
        {
            tcpSocket->abort();
            tcpSocket->connectToHost(QHostAddress(ip), (quint16)port.toUInt());
            QString msgType = "MSG_USER_LOGIN";
            QByteArray block;
            QDataStream out(&block, QIODevice::WriteOnly);
            out.setVersion(QDataStream::Qt_4_6);
            out << (quint16)0 << msgType << usrname << password;
            out.device()->seek(0);
            out << (quint16)(block.size() - sizeof(quint16));
            tcpSocket->write(block);
        }
   
}

 

  登录反馈

void login::on_Read()
{
    QByteArray block = tcpSocket->readAll();
    QDataStream in(&block, QIODevice::ReadOnly);     //QDataStream in(tcpSocket);
    quint16 dataGramSize;
    QString msgType;
    in >> dataGramSize >> msgType;
    if ( "MSG_ID_NOTEXIST" == msgType )
   {
       QMessageBox::warning(NULL, tr("提示"), tr("该号码不存在，请先注册."));
       ui->usrnamelineEdit->clear();
       ui->passwordlineEdit->clear();
   }
    else if ( "MSG_PWD_ERROR" == msgType )
    {
           QMessageBox::information(NULL, tr("提示"), tr("密码错误."));
           ui->usrnamelineEdit->clear();
    }
    else if ( "MSG_LOGIN_ALREADY" == msgType )
    {
           QMessageBox::information(NULL, tr("提示"), tr("请不要重复登录."));
           ui->usrnamelineEdit->clear();
           ui->passwordlineEdit->clear();
    }
    else if ( "MSG_LOGIN_SUCCESS" == msgType)
    {
            qqpanel = new panel(usrname, ip, port);
            qqpanel->setWindowTitle(tr("QQcopy"));
            qqpanel->setWindowFlags(Qt::FramelessWindowHint);
            qqpanel->setAttribute(Qt::WA_TranslucentBackground);
            qqpanel->show();
            this->close();
    }

❀服务器端的监听

   

  

 

  首先Tcp server

void TcpSockServer::incomingConnection(int socketDescriptor)
{
    TcpConThread *thread = new TcpConThread(socketDescriptor, this);
    connect(thread, SIGNAL(finished()), thread, SLOT(deleteLater()));
    thread->start();
}

 窗口构造

Daemon::Daemon(QWidget *parent) :
    QMainWindow(parent),
    ui(new Ui::Daemon)
{
    ui->setupUi(this);
    this->setWindowTitle("QQ");
    ui->startListenButton->setText("开始监听");
    ui->ipLineEdit->setEnabled(true);
    ui->portLineEdit->setEnabled(true);

    ip.clear();
    port.clear();
    db = new SqliteDB;
    tableViewRefresh();

}

数据信息的refresh

void Daemon::tableViewRefresh()
{
    db->connectDB();

    this->myModel = new MySqlQueryModel;
    this->myModel->setQuery(QObject::tr("select id, name, logstat from user order by logstat desc"));
    myModel->setHeaderData(0, Qt::Horizontal, tr("QQ号"));
    myModel->setHeaderData(1, Qt::Horizontal, tr("昵称"));
    myModel->setHeaderData(2, Qt::Horizontal, tr("状态"));

    ui->tableView->setModel(myModel);
    ui->tableView->setColumnWidth(0, 71);
    ui->tableView->setColumnWidth(1, 71);
    ui->tableView->setColumnWidth(2, 71);
    ui->tableView->show();


    db->closeDB();
}

系统广播和聊天UDP即可

void Daemon::on_send()
{
    QByteArray sysMsg;
    QDataStream tosend(&sysMsg,QIODevice::WriteOnly);
    tosend.setVersion(QDataStream::Qt_4_6);
    QString mytype="MSG_SERVER_INFO";
    tosend<<(quint16)0<<mytype<<ui->servTextEdit->toPlainText();
    tosend.device()->seek(0);
    tosend<<(quint16)(sysMsg.size()-sizeof(quint16));
    if(!udpSocket->writeDatagram(sysMsg.data(),sysMsg.size(),QHostAddress("192.168.1.255"),6666))
    QMessageBox::warning(NULL,"message broadcast","error");
    ui->servTextEdit->clear();
}
