By this method all registered EventObersers are notified about every InteractionEvent, the isHandled flag indicates if a DataInteractor has already handled that event. InteractionEventObserver that trigger an action when observing an event may consider this in order to not confuse the user by, triggering several independent action with one single user event (such as a mouse click)

If you want to use the InteractionEventObserver as a state machine give the event to the state machine by implementing, e.g.

void mitk::InteractionEventObserver::Notify(InteractionEvent::Pointer interactionEvent, bool isHandled)
 {
   if (!isHandled) {
     this->HandleEvent(interactionEvent, NULL);
   }
 }

This overwrites the FilterEvents function of the EventStateMachine to ignore the DataNode, since InteractionEventObservers are not associated with one. virtual bool FilterEvents(InteractionEvent* interactionEvent, DataNode* dataNode);

Implements mitk::InteractionEventObserver.
