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

Public Methods

void ~KeyboardListener ()

void OnKeyEvent (::fuchsia::ui::input3::KeyEvent event, OnKeyEventCallback callback)

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`.
