Interface INEventListener

  • All Known Implementing Classes:
    NEventListener, NEventWithResultListener

    public interface INEventListener
    An interface used for creating classes that will listen to any .NET events.

    Classes implementing this interface can be provided as argument to event subscribing method on instance of NObject class.

    When .NET event is raised all associated instances of classes implementing INEventListener will be informed by calling
    eventOccurred method with list of arguments passed by the event invocation.

    Receiving Events Arguments

    All arguments passed by event invocation are either converted to JAVA primitive types (String, Integer, Float..)
    or passed as NObject instances for reference-type arguments.

    Subscribing Events

    Events can be subscribed by calling NObject.addEventListener(String, INEventListener) method.
    Event listener can be an instance of NEventListener class or any other class inheriting from NEventListener,
    class implementing INEventListener interface or anonymous class of NEventListener itself; for example

     button4.addEventListener("Click", new NEventListener() {
     	public void eventOccurred(Object[] arguments) {

    or by instance of class implementing INEventListener interface

     class MyEventListener implements INEventListener
     	public void eventOccurred(Object[] arguments)
     		//my custom event handling code
     button4.addEventListener("Click", new MyEventListener());
