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 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.

    • 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.
