public interface ContainerListener extends EventListener
ContainerAdapter class
(overriding only the methods of interest).
The listener object created from that class is then registered with a
component using the component's addContainerListener
method. When the container's contents change because a component
has been added or removed, the relevant method in the listener object
is invoked, and the ContainerEvent is passed to it.
Container events are provided for notification purposes ONLY;
The AWT will automatically handle add and remove operations
internally so the program works properly regardless of
whether the program registers a ContainerListener or not.
