?寫在開頭

之前只總結了透明、無邊框、可移動窗口的UI處理，為了給某位同學提供些學習資料，我再總結些功能要點。

原則：少說廢話，多上代碼。

?登錄窗口

登錄操作TcpSocket，如果你非要問我為什么不是UDP Socket ，我只能說因為tcp可靠 。

?登錄

在確保設置IP端口后，通過QDataStream寫 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("請輸入QQ號.")); } 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); } }

登錄反饋

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("該號碼不存在，請先注冊.")); ui->usrnamelineEdit->clear(); ui->passwordlineEdit->clear(); } else if ( "MSG_PWD_ERROR" == msgType ) { QMessageBox::information(NULL, tr("提示"), tr("密碼錯誤.")); ui->usrnamelineEdit->clear(); } else if ( "MSG_LOGIN_ALREADY" == msgType ) { QMessageBox::information(NULL, tr("提示"), tr("請不要重復登錄.")); 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(); }

?服務器端的監聽

首先Tcp server

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

窗口構造

Daemon::Daemon(QWidget *parent) : QMainWindow(parent), ui(new Ui::Daemon) { ui->setupUi(this); this->setWindowTitle("QQ"); ui->startListenButton->setText("開始監聽"); ui->ipLineEdit->setEnabled(true); ui->portLineEdit->setEnabled(true); ip.clear(); port.clear(); db = new SqliteDB; tableViewRefresh(); }

數據信息的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號")); myModel->setHeaderData(1, Qt::Horizontal, tr("昵稱")); myModel->setHeaderData(2, Qt::Horizontal, tr("狀態")); ui->tableView->setModel(myModel); ui->tableView->setColumnWidth(0, 71); ui->tableView->setColumnWidth(1, 71); ui->tableView->setColumnWidth(2, 71); ui->tableView->show(); db->closeDB(); }

系統廣播和聊天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(); }
