Class MathComponentListener

java.lang.Object

com.wolfram.jlink.MathListener

com.wolfram.jlink.MathComponentListener

All Implemented Interfaces:

java.awt.event.ComponentListener, java.util.EventListener

public class MathComponentListener
extends MathListener
implements java.awt.event.ComponentListener

This class lets you trigger a call into Mathematica on the occurrence of a particular event. Like all the MathXXXListener classes, it is intended to be used primarily from Mathematica, although it can be used from Java code as well.

In response to a ComponentEvent, objects of this class send to Mathematica:

     userCode[theComponentEvent]

userFunc is specified as a string, either a function name or an expression (like a pure function "foo[#]&"), via the setHandler() method.

Constructor Summary

Constructors

Constructor and Description
MathComponentListener() The constructor that is called from Mathematica.
MathComponentListener(KernelLink ml) You must use this constructor when using this class in a Java program, because you need to specify the KernelLink that will be used.
MathComponentListener(java.lang.String[][] handlers) This form of the constructor lets you skip having to make a series of setHandler() calls.

Constructor Detail

MathComponentListener

public MathComponentListener()

The constructor that is called from Mathematica.

MathComponentListener

public MathComponentListener(KernelLink ml)

You must use this constructor when using this class in a Java program, because you need to specify the KernelLink that will be used.

Parameters:

ml - The link to which computations will be sent when ComponentEvents arrive.

MathComponentListener

public MathComponentListener(java.lang.String[][] handlers)

This form of the constructor lets you skip having to make a series of setHandler() calls. Use this constructor from Mathematica code only.

Parameters:

handlers - An array of {meth, func} pairs associating methods in the ComponentListener interface with Mathematica functions.
