}

class MyMessageBox : public QObject
{
public:
    MyMessageBox();~MyMessageBox();

    static void ChMessageOnlyOk_Information(QString info)
    {
        QMessageBox msg;
        msg.setWindowTitle(tr("提示"));
        msg.setText(info);
        msg.setStyleSheet("font: 14pt;background-color:rgb( 0,220, 0)");
        msg.setIcon(QMessageBox::Information);
        msg.addButton(tr("确定"),QMessageBox::ActionRole);
        msg.exec();
    }

    static void ChMessageOnlyOk_Error(QString info)
    {
        QMessageBox msg;
        msg.setWindowTitle(tr("提示"));
        msg.setText(info);
        msg.setStyleSheet("font: 14pt;background-color:rgb(220, 0, 0)");
        msg.setIcon(QMessageBox::Critical);
        msg.addButton(tr("确定"),QMessageBox::ActionRole);
        msg.exec();
    }

    static int ChMessageOkCancel(QString info)
    {
        QMessageBox msg;
        msg.setWindowTitle(tr("提示"));
        msg.setText(info);
        msg.setStyleSheet("color:rgb(220, 0, 0);font: 14pt");
        msg.setIcon(QMessageBox::Information);
        msg.addButton(tr("确定"),QMessageBox::ActionRole);
        msg.addButton(tr("取消"),QMessageBox::ActionRole);
        return msg.exec();
