I have a Reusable StatusBar class which I created.  I want to be able to add an EventListener for it so that whenever another class wants to set the text in the status bar, it can do so via the StatusBarListener.  How can I do this?

Why using Events and EventListeners?

Simply use a public method in StatusBar that sets its text and refreshes it:

    public void setText(String s)

and add a reference to your status bar in the classes that want to make use of it. It's that simple.

Don't forget that in this actual case, it is the StatusBar that "listens" to other components; if the other components were listening to the StatusBar (the opposite situation), event listeners would be needed.

I don't want any of my gui components to need knowledge of each other.  So I don't want references of other gui components inside each other.
