public class BPDMarqueeHandler
extends org.jgraph.graph.BasicMarqueeHandler

Implementation of a marquee handler for Process Editor. This is also a place where (after mouse click or release) participants, activities (normal, subflows, block activities) and transitions are inserted, where persistent mode is achived and where mouse cursors are changing, and where popup menubar is implemented. When inserting cells it calls WorkflowManager.
