Class JArrow

java.lang.Object
  java.awt.Component
      org.globus.cog.gui.grapheditor.util.swing.JArrow

All Implemented Interfaces:

ImageObserver, MenuContainer, Serializable, SwingEdge

Direct Known Subclasses:

JTextArrow

public class JArrow

extends Component

implements SwingEdge

provides a swing component that can draw an arrow. Additional logic is included since swing/awt components cannot have negative sizes.
