OptionalafterIf overwritten, it is called when a directional navigation finished.
Will be called after the navigation finished regardless if the navigation was successful or not.
If navigation was not successful, the target element will be undefined. This can be used for implementing a
custom behavior when the user navigations at the edge of the spatial components. E.g., presenting an additional
overlay when pressing a direction while the last component is already focused.
ReadonlycontainerOptionalonIf overwritten, allows to implement custom action behavior. Per default, the internal handler will still be
executed. To prevent execution of the default action handler, call preventDefault(). Return true if your
handler consumed the action event. Return false or undefined if it did not. Consumed events will not be
handled any further by spatial navigation.
