SettingsCommand Класс
Определение
Важно!
Некоторые сведения относятся к предварительной версии продукта, в которую до выпуска могут быть внесены существенные изменения. Майкрософт не предоставляет никаких гарантий, явных или подразумеваемых, относительно приведенных здесь сведений.
Примечание
SettingsPane является нерекомендуемой и может работать не во всех версиях Windows 10. Вместо использования SettingsPane интегрируйте параметры параметров в интерфейс приложения. Дополнительные сведения см. в разделе Рекомендации по параметрам приложения.
Создает объект команды settings, представляющий запись параметров. Эту команду параметров можно добавить в вектор ApplicationCommands .

Примечание
Этот класс не является гибким. Это означает, что необходимо учитывать его модель потоков и поведение маршалинга. Дополнительные сведения см. в разделах Потоки и маршалинг (C++/CX) и Использование среда выполнения Windows объектов в многопоточной среде (.NET).
Конструкторы
SettingsCommand(Object, String, UICommandInvokedHandler) |
