Question

我将一个应用程序移植到我在linux上开发的Windows上构建项目时出现以下错误：

 error: C2470: 'final' : looks like a function definition, but there is no parameter list; skipping apparent body

这是我的main.cpp

 #include "mainwindow.h"
#include <QApplication>
#include <ctime>
#include <iostream>
#include <QPixmap>
#include <stdio.h>
#include <QProcess>
#include <QString>
#include <tango.h>
#include <QPainter>
#include <QPen>
#include <QBrush>
#include <QLabel>
#include <QTimer>
#include <ctime>
#include <QMessageBox>


class  Application final : public QApplication {
    Application(int& argc, char** argv) : QApplication(argc, argv) {}
    virtual bool notify(QObject *receiver, QEvent *e) override {
         // your code here


        try
            {
                return QApplication::notify( receiver, e );
            }
            catch(Tango::DevFailed e)
            {
                //QMessageBox::information(this,tr("Update Failed"),tr("Error updating values.Try again."));
            }
            catch(Tango::CommunicationFailed e)
            {
                //QMessageBox::information(this,tr("Communication with device failed"),tr("Error updating values.Try again."));
            }

    }
};

int main(int argc, char *argv[]) try
{
    QApplication a(argc, argv);
    MainWindow w;
    w.show();



    return a.exec();
}

catch (Tango::DevFailed e)
{
    //QMessageBox::information(this,tr("Updating values failed"),tr("Error updating values.Try again."));
}
catch (Tango::CommunicationFailed e)
{
    //QMessageBox::information(this,tr("Communication Failed"),tr("Error updating values.Try again."));
}

这是我的.pro文件：

你可以告诉我这里缺少的东西吗？我认为错误与c ++标准有关，但我不确定如何解决它。

c2470：'final'看起来像一个函数定义，但Qt中没有参数列表错误
