All Implemented Interfaces:

java.awt.event.ActionListener, java.util.EventListener, ForeignReferenceInt

public class RManualFunctionActionListener

extends RForeignReference

implements java.awt.event.ActionListener

A class that allows an R object (function or closure) to be used as an ActionListener for Swing buttons, etc. so that when an event happens on that component, the appropriate R function is invoked. This differs from the automatically generated versions (using the dynamic compiler via ForeignReferenceClassGenerator) in that

• the Java method called by the JButton is native (rather than a method that arranges its arguments into a List and calls an inherited native method with these arguments, the name of the method, and the signature)
• the foreing R object that is to be invoked by the native actionPerformed method should be a function, not a list of functions.
