Doesn't work when use it inside other classes instead of main.cpp

Hi. i want to use your library inside my app. but i don't want to use itin this way(since my app is qt-quick and uses qml/c++ in same time. so i connect every cpp class to a qml file):

QCoreApplication app(argc, argv);
...
QOnlineTranslator translator;
translator.translate("Hello world", QOnlineTranslator::Google);

QObject::connect(&translator, &QOnlineTranslator::finished, [&] {
    if (translator.error() == QOnlineTranslator::NoError)
        qInfo() << translator.translation();
    else
        qCritical() << translator.errorString();
});

Actually it works only in main.cpp and after this line: QCoreApplication app(argc, argv);

I want to use it in other c++ classes that connect them to qml pages. how do that?

It just an example. You can use it inside every class. I use it inside MainWindow. Just create QOnlineTranslator instance, it works as any other QObject. And yes, you need to create an application object first in main.cpp.

Thank you so much.
