public abstract class ContainerAdapter extends Object implements ContainerListener
Extend this class to create a ContainerEvent listener
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 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.
