Class LightweightPeer
java.lang.Object
|
+--java.awt.LightweightPeer
- class LightweightPeer
- extends Object
- implements java.awt.peer.LightweightPeer
Implements the LightweightPeer interface for use in lightweight components
that have no native window associated with them. This gets created by
default in Component so that Component and Container can be directly
extended to create useful components written entirely in java. These
components must be hosted somewhere higher up in the component tree by a
native container (such as a Frame).
This implementation provides no useful semantics and serves only as a
marker. One could provide alternative implementations in java that do
something useful for some of the other peer interfaces to minimize the
native code.
