hey guys,
I'm moving my NWN resource browser off Java3D and onto my new JME loader for its model and area viewers.
Looking at the Swing test in jmetest/utils i managed to get a basic frame u pwitha JME canvas in it, but its pretty ugly stuff.
Im thinking of trying to make something that wraps it and makes it much more like a Swing component so you can just drop it in a layout and go. Before I do it, is this already there somewhere that i missed?
Thanks
JK
Unless I'm confused (which is usually the case) I think JMEDesktop does what you're looking for?
Hmm I think jeffpk is trying to do the opposite: a jME canvas within a Swing app, instead of having Swing widgets rendered by jME.
JK : there's work in progress for precisely the same thing with SWT (works great but with only one canvas for the moment), I guess it should be easier with Swing (since jME works with AWT)
Oh…right…no wonder it didn't make a lot of sense to me what he was asking. 
Yeah Librarian is right, thats what Im up to.
For a game, I want one big JME screen, but for tools its useful to be able to embed the JME in Swing.
Its doable now, just a bit ugly so I guess Ill go ahead and make my component… a JMEJPanel or some such thing.

If you're talking about tools, why not go ahead and use JMEDesktop? If you set it to ortho you could get the same effect in the OpenGL window, right?

i've written a simple class that build swing apps with an embedded jme canvas specifically from the point of view of tools.....
public class SwingJMEFrame extends JFrame implements Runnable, ActionListener
{
protected Canvas mcl_jmeCanvas;
protected SimpleCanvasImpl mcl_canvasImplementor;
private JButton mcl_randClrs;
public int mi_width;
public int mi_height;
public int mi_jmeCanvasWidth;
public int mi_jmeCanvasHeight;
public
SwingJMEFrame(int i_w, int i_h, int i_jmeW, int i_jmeH)
{
mi_width = i_w;
mi_height = i_h;
mi_jmeCanvasWidth = i_jmeW;
mi_jmeCanvasHeight = i_jmeH;
initFrame();
setVisible(true);
// wait for it to come alive
while (mcl_jmeCanvas == null) ;
Thread lcl_runner = new Thread(this);
lcl_runner.setDaemon(true);
lcl_runner.start();
System.out.println("running!!!");
}
/* (non-Javadoc)
* @see java.lang.Runnable#run()
*/
public void
run()
{
try
{
while (true)
{
if (isVisible())
{
mcl_jmeCanvas.repaint();
}
Thread.sleep(2);
}
}
catch (InterruptedException e)
{
e.printStackTrace();
}
}
public void
initFrame()
{
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setLayout(null);
setSize(mi_width, mi_height);
setLocationRelativeTo(null);
getJmeCanvas();
this.getContentPane().add(mcl_jmeCanvas);
initialiseUserComponents();
}
public void
initialiseUserComponents()
{
mcl_randClrs = new JButton("rand");
mcl_randClrs.setBounds(mi_jmeCanvasWidth + 20, 25, 120, 30);
this.getContentPane().add(mcl_randClrs);
mcl_randClrs.addActionListener(this);
}
public Canvas
getJmeCanvas()
{
if(mcl_jmeCanvas == null)
{
buildJMECanvas();
}
return mcl_jmeCanvas;
}
public void
buildJMECanvas()
{
mcl_jmeCanvas = DisplaySystem.getDisplaySystem().createCanvas(mi_jmeCanvasWidth, mi_jmeCanvasHeight);
mcl_jmeCanvas.setSize(new Dimension(mi_jmeCanvasWidth, mi_jmeCanvasHeight));
initialiseImplementor();
((JMECanvas)mcl_jmeCanvas).setImplementor(mcl_canvasImplementor);
}
public void
initialiseImplementor()
{
mcl_canvasImplementor = new SwingJMEImplementor(mi_jmeCanvasWidth, mi_jmeCanvasHeight);
}
public SimpleCanvasImpl
getImpl()
{
return mcl_canvasImplementor;
}
/* (non-Javadoc)
* @see java.awt.event.ActionListener#actionPerformed(java.awt.event.ActionEvent)
*/
public void
actionPerformed(ActionEvent cl_e)
{
if(cl_e.getSource() == mcl_randClrs)
{
((SwingJMEImplementor)mcl_canvasImplementor).lcl_box.setRandomColors();
}
}
/**
* @param args
*/
public static void
main(String[] args)
{
// TODO Auto-generated method stub
SwingJMEFrame lcl_main = new SwingJMEFrame(1024, 768, 640, 480);
}
}
if you want to build a tool using jme and swing just
1. subclass SwingJMEFrame
2. subclass SimpleCanvasImpl
public class SwingJMEImplementor extends SimpleCanvasImpl
{
public Box lcl_box;
/* (non-Javadoc)
* @see com.jmex.awt.SimpleCanvasImpl#simpleSetup()
*/
@Override
public void
simpleSetup()
{
lcl_box = new Box("box1", new Vector3f(0, 0, 0), 5f, 5f, 5f);
lcl_box.setRandomColors();
this.rootNode.attachChild(lcl_box);
}
public
SwingJMEImplementor(int i_w, int i_h)
{
super(i_w, i_h);
}
public void
simpleRender()
{
}
}
3. in the initialiseImplementor() method of the class you created in step 1 instantiate the class that you wrote in step 2...
e.g.
mcl_canvasImplementor = new SwingJMEImplementor(mi_jmeCanvasWidth, mi_jmeCanvasHeight);
4. implement the initialiseUserComponents with whatever components you want
it take all of 1 minute to get a swing app with a jme canvas up and running....
hope that helps....
oh i ripped most of this out of RenParticleEditor....credit where credit is due :)
Handy, thanks.
I gave up on my attempt. I played with it a bit and came to the conclusion that I really don't understand AWT internals well enough to do it right… and the last thing we need is another half-assed way to do it lying around
One of my best friends at Sun knew the AWT stuff in and out, but hes been gone for awhile

Jeff, have you considered just using JMEDesktop inline like I suggested? You would no longer have any need for embedding it anymore then, right? Also, it would offer some other nice features should you choose to use them in the future (such as floating tools inside the OpenGL view).
This app has an awful lot of Swing code arranged in a JFrame already. its my NWN Resource browser and I dont think I want to have to re-engineer. its just not worth it.
I Do have a JME window working in a JFrame, its just not pretty code.
Maybe next utility i build ill try the other way. what are the gotchas/limits of trying
to do Swing within the JME environment?
Btw thanks NComp.
Im generalizing your code just a bit more and then I can use it as the root for any future utilities 8)
The biggest problem with Swing inside jME is it has some issues in JRE 1.6. There are a few places where you end up having to make some changes to existing code, but most of the time you can just drop in existing code to the JMEDesktop and it just works.
