public abstract class AWTAdapter
extends Object
implements EventListener

Convenient adapter forwarding AWT events to NEWT via the event listener model.

You may attach an instance of this adapter to an AWT Component. When an event happens, it is converted to a NEWT event and the given NEWT listener is being called.

This adapter fullfills three use cases. First as a plain utility to write code AWT agnostic, ie write an javax.media.opengl.GLEvenListener and some appropriate NEWT NEWTEventListener.

Attach the javax.media.opengl.GLEvenListener to a NEWT GLAutoDrawable, e.g. GLWindow,
or to an AWT GLAutoDrawable, e.g. GLCanvas.

Attach the NEWT NEWTEventListener to a NEWT component, e.g. Window,
or to an AWT component, e.g. Component.

Common:

    // your demo/render code
    javax.media.opengl.GLEvenListener demo1 = new javax.media.opengl.GLEvenListener() { ... } ;

    // your AWT agnostic NEWT mouse listener code
    com.jogamp.newt.event.MouseListener mouseListener = new com.jogamp.newt.event.MouseAdapter() { ... } ;
 

Default NEWT use case, without using the AWTAdapter:

    // the NEWT GLAutoDrawable and Window
    GLWindow glWindow = GLWindow.create();

    // attach the renderer demo1
    glWindow.addGLEventListener(demo1);

    // attach the NEWT mouse event listener to glWindow
    glWindow.addMouseListener(mouseListener);
 

AWT use case, AWTAdapter used as an AWT event translator and forwarder to your NEWT listener:

    // the AWT GLAutoDrawable and Canvas
    GLCanvas glCanvas = new GLCanvas();

    // attach the renderer demo1
    glCanvas.addGLEventListener(demo1);

    // attach the AWTMouseAdapter to glCanvas, which translates and forwards events to the NEWT mouseListener
    new AWTMouseAdapter(mouseListener).addTo(glCanvas);
 

Previous code in detail:

    AWTMouseAdapter mouseAdapter = new AWTMouseAdapter(mouseListener);
    glCanvas.addMouseListener(mouseAdapter);
    glCanvas.addMouseMotionListener(mouseAdapter);
 

Second use case is just a litte variation of the previous use case, where we pass a NEWT Window
to be used as the source of the event.

    com.jogamp.newt.event.MouseListener mouseListener = new com.jogamp.newt.event.MouseAdapter() { ... } ;

    Component comp = ... ;                 // the AWT  component

    GLWindow glWindow = GLWindow.create(); // the NEWT component

    

    new AWTMouseAdapter(mouseListener, glWindow).addTo(comp);

 

Last but not least, the AWTAdapter maybe used as a general AWT event forwarder to NEWT.

    com.jogamp.newt.event.MouseListener mouseListener = new com.jogamp.newt.event.MouseAdapter() { ... } ;

    Component comp = ... ;                 // the AWT  component

    GLWindow glWindow = GLWindow.create(); // the NEWT component

    glWindow.addMouseListener(mouseListener); // add the custom EventListener to the NEWT component

    

    new AWTMouseAdapter(glWindow).addTo(comp); // forward all AWT events to glWindow, as NEWT events

Constructors

Constructor and Description
AWTAdapter(NEWTEventListener newtListener) Simply wrap aroung a NEWT EventListener, exposed as an AWT EventListener. The NEWT EventListener will be called when an event happens.
AWTAdapter(NEWTEventListener newtListener, Window newtProxy) Wrap aroung a NEWT EventListener, exposed as an AWT EventListener, where the given NEWT Window impersonates as the event's source.
AWTAdapter(Window downstream) Create a pipeline adapter, AWT EventListener. Once attached to an AWT component, it sends the converted AWT events to the NEWT downstream window. This is only supported with EDT enabled!

Method Summary

Methods

Modifier and Type	Method and Description
abstract AWTAdapter	addTo(Component awtComponent) Due to the fact that some NEWT NEWTEventListener are mapped to more than one EventListener, this method is for your convenience to use this Adapter as a listener for all types. E.g.
NEWTEventListener	getNewtEventListener()
Window	getNewtWindow()

Constructor Detail

AWTAdapter

public AWTAdapter(NEWTEventListener newtListener)

Simply wrap aroung a NEWT EventListener, exposed as an AWT EventListener.
The NEWT EventListener will be called when an event happens.

AWTAdapter

public AWTAdapter(NEWTEventListener newtListener,
          Window newtProxy)

Wrap aroung a NEWT EventListener, exposed as an AWT EventListener,
where the given NEWT Window impersonates as the event's source. The NEWT EventListener will be called when an event happens.

AWTAdapter

public AWTAdapter(Window downstream)

Create a pipeline adapter, AWT EventListener.
Once attached to an AWT component, it sends the converted AWT events to the NEWT downstream window.
This is only supported with EDT enabled!

Method Detail

getNewtWindow

public final Window getNewtWindow()

getNewtEventListener

public final NEWTEventListener getNewtEventListener()

addTo

public abstract AWTAdapter addTo(Component awtComponent)

Due to the fact that some NEWT NEWTEventListener are mapped to more than one EventListener, this method is for your convenience to use this Adapter as a listener for all types.
E.g. MouseListener is mapped to MouseListener and MouseMotionListener.
