Qt 项目主进程接收Alarm 后在GUI上显示，并且可以有选择性输出文件

项目主进程接收报警后，将alarm msg 发送给代理， 并将其分发：

    else if (msg.name == "MesLCUalarmRep") {
        QString    errorText;
        QXmlTools    tool;
        int status;
        int code;
        int severity;
        if ( tool.setData(msg.body, errorText) ) {
            QDomElement    root = tool.getDocument()->documentElement();
            QString    tag = root.tagName();
            if ( tag == "Body" ) {
                QDomNode    child = root.firstChild();
                while ( !child.isNull() ) {
                    tag = child.toElement().tagName();
                    if ( tag == "STAT" ) {
                        QString text_status = child.toElement().text();
                      if( text_status == "MesInfo" ){
                            //return;
                        }
                        status = ( text_status.toUpper() == "MESON" ) ? 1 : 0;
                    }
                    else if ( tag == "ErrorType" ) {
                        severity = ( child.toElement().text().toUpper() == "HEAVY" ) ? 1 : 0;
                    }
                    else if ( tag == "ErrorMessage" ) {
                        errorText = child.toElement().text();
                    }
                    else if ( tag == "ErrorCode" ) {
                        code = atoi( child.toElement().text().toLatin1().data() );
                    }
                    child = child.nextSibling();
                }
                   if(code == COMMONDEFECTALARMCODE || code == GLASSBROKENCALLCODE)
                    {
                            debug("enter common defect judge insertAlarm  [%d] waitAlarmList.size:[%d]",code, waitAlarmList.size());
                            switchAlarmCode(code);

                    }
                   sendAlarmDetail2GUI(errorText);

/**
 *@projectName   BoeB9Project
 *@author        Hasan
 **/
void BoeB9QtmCellInlineMain::sendAlarmDetail2GUI(QString errorMsg)
{
    mgrGlassMapCellInlineBoeB9Lst& GlassMapLst =  mgrGlassMapCellInlineBoeB9Lst::GetInstance();

    QString diffMsg = "4H";

    QString errorTIme = QDateTime::currentDateTime().toString("yyyyMMdd-hh:mm:ss");
    QString errorGls = GlassMapLst.GetJobGlassFromkey("GlsID");

    if(errorGls == "") errorGls = "9AAB85001702a1";
    else if(errorGls.size()<14 && errorGls != "") errorGls.append("  ");

    errorMsg = diffMsg + errorTIme + errorGls + errorMsg;

    sendMesGUIOperatorCallMsg(errorMsg);
}

代理将其分发后GUI接收此alarm， 并且将其在独立窗口显示：

void BoeB9InlineMainForm::showOperatorCallMsg(QString msg)
{
    if(msg.startsWith("4H"))
        showAlarmList(msg);
    else
    {
        opCallDialog->insertMassge(msg);
        opCallDialog->show();
    }
}

void BoeB9InlineMainForm::showAlarmList(QString alarmMsg)
{
    alarmListForm->addAlarmItem2List(alarmMsg.mid(2, alarmMsg.size()-1));
    alarmListForm->show();
}

独立窗口代码如此，并且点击窗口上的confirm按钮，可以将其输出文件保存：

#include "alarmlistform.h"
#include "ui_alarmlistform.h"
#include <QMessageBox>

AlarmListForm::AlarmListForm(QWidget *parent, Qt::WindowFlags) :
    QWidget(parent),
    ui(new Ui::AlarmListForm),
    currentRow(-1)
{
    ui->setupUi(this);
    setWindowTitle("Alarm List");

    QString currentDay = QDateTime::currentDateTime().toString("yyyy-MM-dd");
    QString filePath = SMCU_WORK_PATH  "/";
    filePath += currentDay;
    filePath += "-alarmList.dat";
    file = new QFile(filePath);

}

AlarmListForm::~AlarmListForm()
{
    delete ui;
}

void AlarmListForm::addAlarmItem2List(QString alarmMsg)
{
    QListWidgetItem *item = new QListWidgetItem;
    item->setText(alarmMsg);
    ui->listWidget->addItem(item);
}

void AlarmListForm::on_pushButton_clicked()
{
    if(currentRow < 0)
        return;

    showDetailAlarm(currentRow);

    currentRow = -1;
}

void AlarmListForm::on_listWidget_clicked(const QModelIndex &index)
{
    currentRow = ui->listWidget->currentRow();
}

void AlarmListForm::on_pushButton_2_clicked()
{
    int count = ui->listWidget->count();
    for(int index = count; index >= 0; index --)
    {
        QListWidgetItem *item = ui->listWidget->takeItem(index);
        delete item;
    }
    this->close();
}

void AlarmListForm::on_listWidget_doubleClicked(const QModelIndex &index)
{
    showDetailAlarm(ui->listWidget->currentRow());
}

void AlarmListForm::showDetailAlarm(int row)
{
    QListWidgetItem *item = ui->listWidget->item(row);
    QString alarmDetail = item->text();
    int ans = QMessageBox::question(this,
                         tr("Alarm Detail"),
                                    tr(alarmDetail.toLatin1().data()),
                         QMessageBox::Save | QMessageBox::Cancel);
    if(ans == QMessageBox::Save)
    {
        saveAlarm2File(alarmDetail);
        delete item;
    }

}

void AlarmListForm::saveAlarm2File(QString alarmMsg)
{
    if(!file->isOpen())
    {
        if(file->open(QIODevice::Append | QIODevice::Text))
        {
        }
        else
        {
            return;
        }

    }
    if(alarmMsg.size() <= 10)
    {
        QTextStream buff(file);
        buff<<"<Time>" << "alarmMsg.left(10)" << "</Time>";
        return;
    }
    QTextStream buff(file);
    buff<<"<Time>" << alarmMsg.mid(0, 17) << "</Time>";
    buff<<"<GlsID>" << alarmMsg.mid(17, 14) << "</GlsID>";
    buff<<"<AlarmMsg>" << alarmMsg.mid(31, alarmMsg.size()-1) << "</AlarmMsg>";
    buff<<endl;

    buff.flush();
    file->close();
