Class (EventResult)

Represents the event consumption result sent to the Web component. For details about the supported events, see TouchType, MouseAction, and left, middle, and right buttons in MouseButton.

If the application does not consume the event, set the consumption result to false, and the event will be consumed by the Web component. If the application consumes the event, set the consumption result to true, and the Web component will not consume the event. If the consumption result is not set according to the preceding specifications, exceptions may occur.

For details about the sample code of the touch event, see onNativeEmbedGestureEvent.

For details about the sample code of the mouse event, see onNativeEmbedMouseEvent.
