com.wolfram.jlink
Class MathKeyListener

java.lang.Object
  com.wolfram.jlink.MathListener
      com.wolfram.jlink.MathKeyListener

All Implemented Interfaces:

java.awt.event.KeyListener, java.util.EventListener

public class MathKeyListener
extends MathListener
implements java.awt.event.KeyListener

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 KeyEvent, objects of this class send to Mathematica:

     userCode[theKeyEvent, theKeyEvent.getKeyChar(), theKeyEvent.getKeyCode()]

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

Constructor Summary

MathKeyListener()
The constructor that is called from Mathematica.

MathKeyListener(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.

MathKeyListener(java.lang.String[][] handlers)
This form of the constructor lets you skip having to make a series of setHandler() calls.

Method Summary

void	keyPressed(java.awt.event.KeyEvent e)
void	keyReleased(java.awt.event.KeyEvent e)
void	keyTyped(java.awt.event.KeyEvent e)

Methods inherited from class com.wolfram.jlink.MathListener

Constructor Detail

MathKeyListener

public MathKeyListener()

The constructor that is called from Mathematica.

MathKeyListener

public MathKeyListener(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 KeyEvents arrive.

MathKeyListener

public MathKeyListener(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 KeyListener interface with Mathematica functions.
