Remarks

This API is intended for use by Accessibility tools as a low level hook for intercepting events from hardware system buttons.

SystemButtonEventController event registration applies system wide and is first-come, first-served. If an application or service sets a SystemButtonEventController event Handled property to true, applications or services that registered after that app or service for the same event notification will not receive the notification.

Properties

Handled

Gets or sets a value that marks the SystemFunctionButtonPressed and SystemFunctionButtonReleased events as handled.

Timestamp

Gets the date and time of the SystemFunctionButtonPressed and SystemFunctionButtonReleased events.
