SettingsCommand Класс

Определение

Пространство имен:

Windows.UI.ApplicationSettings

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 .

Комментарии

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)

Создает новую команду settings.

Свойства

AccountsCommand	Возвращает команду для учетной записи в области параметров учетной записи.
Id	Получает или задает идентификатор команды.
Invoked	Возвращает или задает обработчик для события, которое возникает при выборе пользователем команды.
Label	Возвращает или задает метку для команды.
