<h2>NEWT - JOGL&#8217;s High Performance Native Windowing Toolkit</h2>

<h4>NEWT Usage</h4>

<p>
Consider the classic demo code
    <a href="http://jogamp.org/git/?p=jogl.git;a=blob;f=src/test/com/jogamp/opengl/test/junit/jogl/demos/es2/GearsES2.java;hb=HEAD">GearsES2.java</a>
    [<a href="http://jogamp.org/git/?p=jogl.git;a=blob;f=src/test/com/jogamp/opengl/test/junit/jogl/demos/es2/GearsES2.java;h=d92d98894acc4cfe42e77ec316858d16d202b5b8;hb=HEAD">v2.0-rc3</a>],
which implements a
<a href="/deployment/jogamp-next/javadoc/jogl/javadoc/javax/media/opengl/GLEventListener.html">GLEventEventListener</a>.</p>

<p>
The simple application
<a href="http://jogamp.org/git/?p=jogl.git;a=blob;f=src/test/com/jogamp/opengl/test/junit/jogl/demos/es2/newt/TestGearsES2NEWT.java;hb=HEAD">TestGearsES2NEWT.java</a>
    [<a href="http://jogamp.org/git/?p=jogl.git;a=blob;f=src/test/com/jogamp/opengl/test/junit/jogl/demos/es2/newt/TestGearsES2NEWT.java;h=df86b83d2c3af9efed44d973aac24e678e85cd4c;hb=HEAD">v2.0-rc3</a>]
creates a NEWT 
<a href="/deployment/jogamp-next/javadoc/jogl/javadoc/com/jogamp/newt/opengl/GLWindow.html">GLWindow</a>,
which implements a
<a href="/deployment/jogamp-next/javadoc/jogl/javadoc/javax/media/opengl/GLAutoDrawable.html">GLAutoDrawable</a>
and hence is able to add the demo code.
NEWT&#8217;s GLWindow also implements the NEWT <a href="/deployment/jogamp-next/javadoc/jogl/javadoc/com/jogamp/newt/Window.html">Window</a>,
which gives you full control of the native windowing, as shown in the demo.</p>

<p>
Finally we just add our GLWindow to an
<a href="/deployment/jogamp-next/javadoc/jogl/javadoc/com/jogamp/opengl/util/Animator.html">Animator</a> instance,
which renders our demo in it's own rendering thread independent from user input.</p>

<p>
For NEWT&#8217;s AWT integration, please read the dedicated section below.
</p>

<h4>NEWT Threading Overview</h4>

<p>NEWT&#8217;s event model is pretty simple.<br />
It spawns one Event Dispatch Thread (EDT) for each unique Display which role is to handle:</p>
<ul>
<li> input events </li>
<li> window lifecycle actions (window visibility, resize, .. etc) </li>
<li> <b>not</b> rendering </li>
</ul>

<p>
High performance rendering is achieved without being blocked by input events or vice versa.<br/>
As demonstrated in the above NEWT example, rendering does not disturb or lag user input.<br/>
This gives you fluent animation even for complex models.</p>

<h4>NEWT&#8217;s AWT integration and NEWT Applet&#8217;s</h4>

<p>
<a href="/deployment/jogamp-next/javadoc/jogl/javadoc/com/jogamp/newt/awt/NewtCanvasAWT.html">NewtCanvasAWT</a>,
representing an AWT Canvas, allows you to hook a NEWT Window into it.</p>
Since the NewtCanvasAWT is an AWT heavyweight Component, this gives you the ability hook NEWT into an AWT UI.<br/>
<p>
The implementation uses the AWT native JAWT API to reparent the NEWT Window natively into the AWT one<br/>
and hence is even more compatible with JOGL&#8217;s GLCanvas implementation.</p>
<p>
This enables us to use both worlds, AWT/Swing UI and decoupled high performance rendering.</p>

<p>
<a href="http://jogamp.org/git/?p=jogl.git;a=blob;f=src/test/com/jogamp/opengl/test/junit/newt/parenting/TestParenting01cAWT.java;hb=HEAD">TestParenting01cAWT.java</a>
[<a href="http://jogamp.org/git/?p=jogl.git;a=blob;f=src/test/com/jogamp/opengl/test/junit/newt/parenting/TestParenting01cAWT.java;h=4477c3f8e8ebc43c91ea90a82af69a5bb0f38091;hb=HEAD">v2.0-rc3</a>] 
shows you how to add an GLWindow to an NewtCanvasAWT, which iself is added to an AWT Frame.<br/>
It also shows how the NewtCanvasAWT can be easily removed from the AWT Frame and placed into another AWT Container.<br/>
Since we use native reparenting, the native window resource keeps alive and hence your OpenGL application (GLEventListener)
is not being asked to dispose all resources.<br/> 
<a href="http://jogamp.org/git/?p=jogl.git;a=blob;f=src/test/com/jogamp/opengl/test/junit/newt/parenting/TestParenting01cSwingAWT.java;hb=HEAD">TestParenting01cSwingAWT.java</a>
[<a href="http://jogamp.org/git/?p=jogl.git;a=blob;f=src/test/com/jogamp/opengl/test/junit/newt/parenting/TestParenting01cSwingAWT.java;h=478e00007b14f2d4d14da3d5ccca0500b441ba96;hb=HEAD">v2.0-rc3</a>] 
shows the same example using Swing.<br/>
</p>

<p>
Last but not least, the above mechanism can be used to show NEWT Window&#8217;s in an AWT Applet.<br/>
<a href="/deployment/jogamp-next/javadoc/jogl/javadoc/com/jogamp/newt/awt/applet/JOGLNewtApplet1Run.html">JOGLNewtApplet1Run</a>
is an Applet launcher for any
<a href="/deployment/jogamp-next/javadoc/jogl/javadoc/javax/media/opengl/GLEventListener.html">GLEventEventListener</a>
exposing a default constructor.
See it <a href="/deployment/jogamp-next/jogl-test-applets.html"><i>alive</i> here</a>.

<p>We provide some utilities to make life a bit easier.<br />
These are not really necessary, ie you could write and use your own, sure.</p>
<p>The NEWT threading requirements are easy &#8211; they are just <b>none</b> for rendering,<br />

and the input event listener should better not lock the rendering GL context.<br />
Well, they can using <code>GLContext.setSynchronized(true) etc .. </code>,<br />
but that would be a pity performance wise.</p>
