Я новичок в c ++, и я пытаюсь понять, как получить состояние от кнопки и, чтобы для каждого состояния происходило отдельное событие.Я определил условие if () (закомментированное в capslock), как вы можете видеть в коде, но я получаю ошибку на visual studio C3867
Ошибка C3867 'vtkButtonRepresentation :: GetState': не стандартный синтаксис;Вы должны использовать '&', чтобы создать указатель на член
