C++ (Cpp) setComboBoxEnabled примеры использования

Пример #1

Файл: mainwindow.cpp Проект: hitxqh/helloworld

//打开串口
void MainWindow::on_actionOpen_triggered()
{
    QString portName = ui->portNameComboBox->currentText();   //获取串口名
    myCom = new Win_QextSerialPort(portName, QextSerialBase::Polling);
    //这里QextSerialBase::QueryMode应该使用QextSerialBase::Polling

    if(myCom->open(QIODevice::ReadWrite)){
        QMessageBox::information(this, tr("打开成功"), tr("已成功打开串口 ") + portName, QMessageBox::Ok);
    }else{
        QMessageBox::critical(this, tr("打开失败"), tr("未能打开串口 ") + portName + tr("\n该串口设备不存在或已被占用"), QMessageBox::Ok);
        return;
    }

    //设置波特率
    myCom->setBaudRate((BaudRateType)ui->baudRateComboBox->currentIndex());

    //设置数据位
    myCom->setDataBits((DataBitsType)ui->dataBitsComboBox->currentIndex());

    //设置校验
    myCom->setParity((ParityType)ui->parityComboBox->currentIndex());

    //设置停止位
    myCom->setStopBits((StopBitsType)ui->stopBitsComboBox->currentIndex());

    //界面控制
    ui->sendmsgBtn->setEnabled(true);
