public class VirtualFramePeer

extends VirtualComponentPeer

implements java.awt.peer.FramePeer

Virtual frame peer. Satisfies the requirements for AWT frame peers without actually displaying anything (hence, it is virtual). It manages its own Graphics by creating a Raster (single pixel packed sample model) that can be accessed by a PixelsOwner. Virtual frame peers are created by a VirtualToolkit for frames that implement PixelsOwner.
