Switch back to native language after install qm file by QTranslator

tham

I would like to switch back to native language after translation are done, but can't find a way to do it.

#include <QApplication>
#include <QDebug>
#include <QPushButton>
#include <QTranslator>

int main(int argc, char *argv[])

{
    QApplication app(argc, argv);

    QTranslator translator;
    translator.load("hellotr_la");
    app.installTranslator(&translator);

    QPushButton hello(QPushButton::tr("Hello world!"));
    hello.resize(100, 30);

    QTranslator default_language;  

    QObject::connect(&hello, &QPushButton::clicked, [&]()
    {
        static int removed = false;
        if(removed){
            qDebug()<<"translator reinstall";
            app.installTranslator(&translator);
            removed = false;
        }else{
            qDebug()<<"translator removed";
            removed = QCoreApplication::removeTranslator(&translator);
           //with or without this line, the result is same, the language never convert back to english
            app.installTranslator(&default_language);
        }
    });

    hello.show();
    return app.exec();
}

What is the proper way to do it?Thanks
