Global Navigation: Events

Note: Since version 1.56 the EventCentral class is no longer used. Instead, the NavigationManager itself handles the events.

So, everywhere where it was “EventCentral.getInstance().addEventListener(……” you can use the NavigationManager instance, for example: “navigationManager.addEventListener(….”. That is the only difference. This should only concern you if you want to set up more than one global navigation.
