jvx.math.MathListener

jvx.math.MathPickListener

All Implemented Interfaces:

PvPickListenerIf

public class MathPickListener
extends MathListener
implements PvPickListenerIf

Listener to receive pick events of the display to invoke Mathematica commands. The pick event contains information about the picked geometry, the picked geometry vertex and information about mouse position.
