Вызовите это из QWidget: Parser->xmlParser(_layout, xmlPath, comingFrom, mapCount);, но получите две ошибки «Нет подходящей функции для вызова ...».
Нет соответствующей функции для вызова QMap<QMap<QString, QString>, int>::insert Нет соответствующей функции для вызова QList<QMap<QString, QString>>::append
