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.
