public interface ContainerListener extends EventListener
ContainerAdapterclass (overriding only the methods of interest). The listener object created from that class is then registered with a component using the component's
addContainerListenermethod. 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
ContainerEventis 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.
