The LightweightPeer interface marks a component as depending upon a native container so window related events can be routed to the component.

  The LightweightPeer interface marks a component as depending upon a native container so window related events can be routed to the component. Since this only applies to components and their extensions, this interface extends ComponentPeer.

The peer interfaces are intended only for use in porting the AWT. They are not intended for use by application developers, and developers should not implement peers nor invoke any of the peer methods directly on the peer instances.
