Class IconExample.InvisiblePortView

java.lang.Object
  org.jgraph.graph.AbstractCellView
      org.jgraph.graph.PortView
          org.jgraph.example.IconExample.InvisiblePortView

All Implemented Interfaces:

java.io.Serializable, org.jgraph.graph.CellView

Enclosing class:

IconExample

public class IconExample.InvisiblePortView
extends org.jgraph.graph.PortView

This "invisible port" is the same size as the icon on the icon/description vertex. We do this by navigating up the tree to get the CellView, then the CustomCell to get the actual icon height/width. Keep in mind that we are also changing the location of the port such that it is in the same place as the icon displayed on the screen. The port renderer is designed so that it doesn't paint anything.
