  org.strbio.util.graph.ClickablePointPlot

All Implemented Interfaces:

Graph2D.ClickListener, Graphable2D

public class ClickablePointPlot
extends java.lang.Object
implements Graphable2D, Graph2D.ClickListener

A component that acts like it's displaying points, but only circles the one that's been clicked on. Also, a callback function in ClickListener gets called when the point is clicked. It should be overlayed with a PointPlot or PointColorPlot to work.
