Forcing listener execution

Question

I have a problem.

I have an object with a listener attached to it.

I'd like to be able to manually execute it, somehow trick it that the event that triggers it occurred. Maybe there's a way to access the specific listener and tell it to execute?

Object is Box.Filler and listener is ComponentListener (adapter, acctually). It's activated on ComponentResized event.

Answer 1

Well if you were using ComponentListener my guess is you could call it directly:

listener.componentResized(new ComponentEvent (this,id))

If you were using an adapter

adapter.componentResized(new ComponentEvent (this,id))

If your class implements ComponentListener

componentResized(new ComponentEvent (this,id))

Answer 2

You can manually fire an event. If you are using ComponentListener then you can use one of the methods listed in this interface, see http://docs.oracle.com/javase/1.4.2/docs/api/java/awt/event/ComponentListener.html.
