All Implemented Interfaces:

java.awt.event.ActionListener, java.awt.event.ItemListener, java.awt.event.MouseListener, java.awt.event.MouseMotionListener, java.awt.image.ImageObserver, java.awt.MenuContainer, java.io.Serializable, java.util.EventListener, javax.accessibility.Accessible, javax.swing.RootPaneContainer, DiagramListener, DnDContainer, WorkflowEditListener

public class WorkflowApplet
extends javax.swing.JApplet
implements java.awt.event.ActionListener, java.awt.event.ItemListener, DiagramListener, WorkflowEditListener, DnDContainer, java.awt.event.MouseListener, java.awt.event.MouseMotionListener

This class is used to test the workflow diagram display and export code. The main program is invoked with a text file containing the nodes and relationships.

The files entries are comments preceeded by '#', nodes and realtionships. The format of these type of lines are

node,id,row,column,description,type,image resource

The work 'node' identifies the line - for example

node,1,0,0,Start,start,/psdi/webclient/applet/wfcanvas/resources/start.gif
                                         s

relationship,fromID,toID

The word 'relationship' identifies the line - for example

relationship,1,2
