Enum KeyboardListenerRequest

pub enum KeyboardListenerRequest {
    OnKeyEvent {
        event: KeyEvent,
        responder: KeyboardListenerOnKeyEventResponder,
    },
}

Client should implement this protocol to get notified of key events.

Variants

OnKeyEvent

Called when a key event takes place, such as key press or release.

Protocol implementers must respond to acknowledge the event by returning Status in a timely manner, i.e. not introducing significant delays to the input pipeline (typically 10s of milliseconds).

Returning NOT_HANDLED means the event may be offered to other clients of other related APIs.

Clients that do not acknowledge their events will eventually be disconnected.

Notification is only dispatched to a view that has focus. No other views, including parents or children, will get notified specifically via OnKeyEvent.

Fields

event: KeyEvent

responder: KeyboardListenerOnKeyEventResponder
