Extend this class to create a
and override the methods for the events of interest. (If you implement the
ContainerListener interface, you have to define all of
the methods in it. This abstract class defines null methods for them
all, so you can only have to define methods for events you care about.)
Create a listener object using the extended class and then register it with
a component using the component's
method. When the container's contents change because a component has
been added or removed, the relevant method in the listener object is invoked,
ContainerEvent is passed to it.
