| A low-level event which indicates that a component moved, changed
size, or changed visibility (also, the root class for the other
component-level events).
Component events are provided for notification purposes ONLY;
The AWT will automatically handle component moves and resizes
internally so that GUI layout works properly regardless of
whether a program is receiving these events or not.
In addition to serving as the base class for other component-related
events (InputEvent, FocusEvent, WindowEvent, ContainerEvent),
this class defines the events that indicate changes in
a component's size, position, or visibility.
This low-level event is generated by a component object (such as a
List) when the component is moved, resized, rendered invisible, or made
visible again. The event is passed to every ComponentListener
or ComponentAdapter object which registered to receive such
events using the component's addComponentListener method.
(ComponentAdapter objects implement the
ComponentListener interface.) Each such listener object
gets this ComponentEvent when the event occurs.
