All Implemented Interfaces:

java.awt.print.Printable, java.io.Serializable, java.lang.Cloneable

Direct Known Subclasses:

PSWTBoundsHandle

public class PSWTHandle
extends PSWTPath

PHandle is used to modify some aspect of Piccolo when it is dragged. Each handle has a PLocator that it uses to automatically position itself. See PBoundsHandle for an example of a handle that resizes the bounds of another node.
