QOnlineTranslator

QOnlineTranslator is a library for Qt5 that provides free usage of Google, Yandex, Bing, LibreTranslate and Lingva translate API.

Example:

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();
});

return QCoreApplication::exec();

For real example of usage you can look into my other project: Crow Translate.
