Basic embedding of JZY3D into Swing: What am I doing wrong?

[Jeremy McCormick]

Hi,

I finally got more of a handle on how the Canvas implementations work.  So now I'm trying to embed into Swing but without much success. 

Can someone tell me what I'm doing wrong?

Here's the code...

----------------------------------------------

package jzy3d.example;

import java.awt.Canvas;

import java.awt.Panel;

import javax.swing.JFrame;

import javax.swing.JPanel;

import junit.framework.TestCase;

import org.jzy3d.chart.Chart;

import org.jzy3d.colors.Color;

import org.jzy3d.maths.Coord3d;

import org.jzy3d.plot3d.primitives.Scatter;

public class Cloud3DTest extends TestCase {

            

    public static void plot(String canvasType) {

// Create a test chart.

int size = 100000;

Coord3d[] points = new Coord3d[size];

for (int i=0; i<size; i++) {

   points[i] = new Coord3d(

   (float) Math.random() - 0.5f, 

   (float) Math.random() - 0.5f, 

   (float) Math.random() - 0.5f);    

}

Scatter scatter = new Scatter(points);

scatter.setColor(Color.BLUE);

Chart chart = new Chart(canvasType);

chart.getAxeLayout().setMainColor(Color.WHITE);

chart.getView().setBackgroundColor(Color.BLACK);

chart.getScene().add(scatter);

// Embed into Swing.

JFrame frame = new JFrame();

JPanel panel = new JPanel();

panel.setOpaque(false);

if (chart.getCanvas() instanceof Canvas) {

   panel.add((Canvas) chart.getCanvas());

} else if (chart.getCanvas() instanceof Panel) {

   panel.add((Panel) chart.getCanvas());

}

frame.setContentPane(panel);

frame.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);

frame.pack();

frame.setTitle(canvasType);

frame.setVisible(true);

    }

        

     public static void main(String args[]) {

plot("swing");

plot("newt");

plot("awt");

    }        

}

----------------------------------------------

None of the three canvas types show anything.  In fact, the parent JPanel is quite tiny so it isn't even sized correctly.  

Am I doing something dumb?  Or missing something obvious here?  Probably both...

BTW, it seems that putting the component directly into a frame works okay, at least for the "newt" canvas.

This doesn't work with Swing though.  The chart fails to display and just shows random screen junk.  (kind of odd)

I really need to embed the JZY3D components inside JPanels though, and I can't get that to work.  It just shows grey.

Hi Jeremy,
within the following demo project

https://github.com/nilshoffmann/netbeans-jogl2/blob/master/src/net/nilshoffmann/jogl2demo/Jzy3DDemoTopComponent.java

I add a Jzy3d chart using the NEWT canvas to a TopComponent, which is essentially a JComponent/JPanel.

Maybe that can give you a hint.

Nils

Hi,
You answered your own question :) You should use Newt.

I made this more clear in the swing canvas javadoc
https://github.com/jzy3d/jzy3d-api/blob/master/src/api/org/jzy3d/plot3d/rendering/canvas/CanvasSwing.java

Hi,

The link you gave is broken (the class doesn't exist).

I have tried to instanciate a Chart with "newt" Canva (though I'm new to this and don't know precisely what are the implications, I just want to integrate a 3D graph in a JPanel in my window) but I get a "unhandled canvas!" exception:

Chart chart = new Chart(Quality.Advanced, "newt");

unhandled canvas! org.jzy3d.plot3d.rendering.canvas.CanvasNewt[panel0,0,0,0x0,invalid,layout=java.awt.FlowLayout]

From the sources, I found out that only CanvaSwing, CanvaAWT and OffscreenCanvas are handled in View constructor, though "newt" is valid in Chart constructor.
I tried with "swing" instead of "newt" but I get a blank screen instead of my Spheres.

I'm using jzy3d-0.9. I tried Jeremy's code but I still get the same Exception thrown out.
Am I missing something obvious?

Regards,
Matthieu

Hi,

Sorry for late reply.

This is a known bug of 0.9. To work with ongoing 0.9.1 and this bug fixed, you should use the maven repository as explained in this readme:
https://github.com/jzy3d/jzy3d-master

Cheers,
Martin
