In the case of TouchEvent or Gesture, there is no way to propagate the event to the view below that is not related.
So, before sending an touch event, send an hitTestResult event to the view in the hit-test process to ask whether it will be hit or not.
If it returns false, it means that it will not be hit, and the hit-test continues to the next view.

+ * @code
+ * void MyCallbackName( Actor actor );
+ * @endcode
+ * actor The actor to intercept
+ *
+ * @note This callback is called when the actor is hit.
+ * If true is returned, TouchEvent is called from the this actor.
+ * If false is returned, the hit test starts again from the next lower actor.
+ *
+ * @note example
+ * Actor topActor = Actor::New();
+ * Actor bottomActor = Actor::New();
+ * topActor.TouchedSignal().Connect(&application, topActorFunctor);
+ * bottomActor.TouchedSignal().Connect(&application, bottomActorFunctor);
+ * The two actors have no relationship.
+ * So when the topActor is touched, the event cannot be propagated to the bottomActor.
+ *
+ * If you connect HitTestResultSignal to topActor.
+ * Dali::DevelActor::HitTestResultSignal(topActor).Connect(&application, hitTestResultFunctor);
+ *
+ * If the hitTestResult Functor returns false, it passes the hit-test and starts the hit-test again from the next lower actor.
+ * So the bottomActor can be hit and receive touch events.
+ * If hitTestResult returns true, it means that it has been hit. So it receives a TouchEvent from itself.
