AutomationProperty

Примеры

В следующем примере получается коллекция целочисленных идентификаторов, представляющих текущие представления, доступные для элемента управления, который поддерживает MultipleViewPattern .In the following example, a collection of integer identifiers is obtained that represents the current views available for a control that supports MultipleViewPattern.

Комментарии

Этот идентификатор используется клиентскими приложениями модели автоматизации пользовательского интерфейса.This identifier is used by UI automation client applications. Поставщики автоматизации пользовательского интерфейса должны использовать эквивалентное поле в MultipleViewPatternIdentifiers .UI Automation providers should use the equivalent field in MultipleViewPatternIdentifiers.

Это свойство отсутствует в MultipleViewPattern.MultipleViewPatternInformation и должно быть получено с помощью GetCurrentPropertyValue или GetCachedPropertyValue .This property is not present in MultipleViewPattern.MultipleViewPatternInformation and must be retrieved by using GetCurrentPropertyValue or GetCachedPropertyValue.
