Foil 18 Hooking up Beans with events

From JavaBeans and Use in ComponentWare Basic Information Track Computational Science Course CPS616 -- March 25 1998. by Nancy McCracken, Geoffrey C. Fox, Wojtek Furmanski
1 Consider the standard example of hooking up two buttons to start and stop the Juggler animation bean.
2 First we place a button and name it start. We want to hook up its actionEvent with the method called start() in the Juggler, which starts the animation.
3 The BeanBox allows us to select the actionPerformed event from the "button push" menu, select the Juggler bean to be the target, and select its start method.
4 What this does is to create a class that implements an ActionListener (or inherits from the ActionListener adapter class).
