Package 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

    Constructors 
    Constructor Description
    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.

  • Constructor Details

    • 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.
