Class MathActionListener

java.lang.Object
com.wolfram.jlink.MathListener
com.wolfram.jlink.MathActionListener
All Implemented Interfaces:
java.awt.event.ActionListener, java.util.EventListener

public class MathActionListener
extends MathListener
implements java.awt.event.ActionListener
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 an ActionEvent, objects of this class send to Mathematica:

     userFunc[theActionEvent, theActionEvent.getActionCommand()]
userFunc is specified as a string, either a function name or an expression (like a pure function "foo[##]&"), via the setHandler() method. Sending the result of getActionCommand() is an optimization to avoid a call back to Java in the likely event that you want this value.
  • Constructor Summary

    Constructors 
    Constructor Description
    MathActionListener()
    The constructor that is typically called from Mathematica.
    MathActionListener​(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.
    MathActionListener​(java.lang.String func)
    Because the ActionListener interface has only one method, actionPerformed(), you can specify the Mathematica function to be called with this constructor, rather than having to separately call setHandler().

    • MathActionListener

      public MathActionListener()
      The constructor that is typically called from Mathematica.
    • MathActionListener

      public MathActionListener​(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 actionPerformed() is called.
    • MathActionListener

      public MathActionListener​(java.lang.String func)
      Because the ActionListener interface has only one method, actionPerformed(), you can specify the Mathematica function to be called with this constructor, rather than having to separately call setHandler(). Use this constructor from Mathematica code only.
      Parameters:
      func - The Mathematica function to be executed in response to an ActionEvent.
