В подклассе QSettings нет ключей

Я работаю над проектом как дополнение к существующему Java-приложению. Это приложение Java имеет свой конфигурационный файл, как это:В подклассе QSettings нет ключей

сейчас, что я делаю на стороне Qt C++, я не могу получить значения из ключей. Поэтому я подклассы QSettings класс, как здесь:

Теперь, все, что я делаю, Я, что короткий метод с помощью ueRead ...., например, ueReadUser() возвращает пустую строку. Кто-нибудь знает, что я делаю неправильно?

Это не так, как вы черпаете 'QSettings'. [Так вы получаете QSettings] (http://doc.qt.io/qt-5/qsettings.html#registerFormat). – Amartel

@Amartel у вас есть пример, потому что я понятия не имею, как реализовать 'readFunc' и' writeFunc' – KernelPanic

Не уверен, что это помогает, но это [моя реализация XmlSettings] (https://yadi.sk/ д/8aEmohpzi7QyZ). – Amartel
