Class AWTAdapter

java.lang.Object

com.jogamp.newt.event.awt.AWTAdapter

All Implemented Interfaces:

EventListener

Direct Known Subclasses:

AWTKeyAdapter, AWTMouseAdapter, AWTWindowAdapter

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

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.
AWTAdapter	clear() Removes all references, downstream and NEWT-EventListener.
NativeSurfaceHolder	getNativeSurfaceHolder() Returns the NativeSurfaceHolder acting as downstream, NEWT window proxy or as an NativeSurfaceHolder proxy.
NEWTEventListener	getNewtEventListener() Returns the NEWT event-listener if instance is used as an NativeSurfaceHolder proxy or NEWT window proxy, otherwise method returns null.
Window	getNewtWindow() Returns the NEWT Window acting as downstream or as a NEWT window proxy.
abstract AWTAdapter	removeFrom(Component awtComponent)
void	setConsumeAWTEvent(boolean v)
AWTAdapter	setDownstream(Window downstream) Setup 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

setDownstream

public AWTAdapter setDownstream(Window downstream)
                         throws IllegalStateException

Setup 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!

Throws:

IllegalStateException - if EDT is not enabled

clear

public AWTAdapter clear()

Removes all references, downstream and NEWT-EventListener.

Also sets the internal setup flag and setConsumeAWTEvent(boolean) to false.

setConsumeAWTEvent

public final void setConsumeAWTEvent(boolean v)

getNativeSurfaceHolder

public final NativeSurfaceHolder getNativeSurfaceHolder()

Returns the NativeSurfaceHolder acting as downstream, NEWT window proxy or as an NativeSurfaceHolder proxy.

Returned value is never null.

getNewtWindow

public final Window getNewtWindow()

Returns the NEWT Window acting as downstream or as a NEWT window proxy.

Returned value maybe null if instance is used to be a NativeSurfaceHolder proxy.

getNewtEventListener

public final NEWTEventListener getNewtEventListener()

Returns the NEWT event-listener if instance is used as an NativeSurfaceHolder proxy or NEWT window proxy, otherwise method returns null.

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.

removeFrom

public abstract AWTAdapter removeFrom(Component awtComponent)
