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 SystemFunctionLockChanged event as handled.
IsLocked

Gets the state of the Fn hardware system button lock for the SystemFunctionLockChanged event.
