Yes why shouldn't it be possible to do it ? You can look into EventBus/SimpleEventBus for that which is bascially an implementation of the Observer pattern.

ok; thank you

by the way; have you any good link which will help me to do that; as i know the Event bus is used to register events triggered on the UI compenents.

You will be creating your own EventBus that only handles whatever you tell it to.
