GridBagLayout

[Gast]

huhu,
ich versuche mich gerade am GridBagLayout,
docht irgendwie will das nicht so wie ich^^.

import javax.media.j3d.BranchGroup;
import javax.media.j3d.Canvas3D;
import javax.swing.*;
import com.sun.j3d.utils.geometry.ColorCube;
import com.sun.j3d.utils.universe.SimpleUniverse;
import java.awt.*;
import java.util.Hashtable;

public class Test
{
	public static void main(String [] args)
	{
		JFrame frame = new JFrame();
		frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		frame.setSize(800,600);
		Container inhalt = frame.getContentPane();

		inhalt.setLayout( new GridBagLayout() );
		GridBagConstraints c = new GridBagConstraints();
		c.weightx = 55;
		c.weighty = 55;

		JPanel panel = new JPanel();
		panel.setLayout(new GridLayout(2,1));
		panel.add( new JLabel("#Balls") );
		JSpinner spinner = new JSpinner(new SpinnerNumberModel(0, 0, 5, 1));
		spinner.setEditor(new javax.swing.JSpinner.NumberEditor(spinner));
		panel.add(spinner);	
		c.gridx = 1;
		c.gridy = 0;
		c.gridwidth = 1;
		c.gridheight = 1; 
		inhalt.add( panel, c );

        // Begin JAVA3D -> Problem: Wird nicht angezeigt.
		JPanel panel3d = new JPanel();
		c.gridx = 1;
		c.gridy = 1;
		c.gridwidth = 1;
		c.gridheight = 1; 
		GraphicsConfiguration config 	= SimpleUniverse.getPreferredConfiguration();
		Canvas3D canvas					= new Canvas3D(config);;
		panel3d.add( canvas);
		inhalt.add(  panel3d, c );
		SimpleUniverse universe			= new SimpleUniverse(canvas);
		universe.getViewingPlatform().setNominalViewingTransform();
		BranchGroup bg = new BranchGroup();
		bg.addChild(new ColorCube(0.5f));
		bg.compile();
		universe.addBranchGraph(bg);
		//END JAVA3D

		c.gridx = 1;
		c.gridy = 2;
		c.gridwidth = 1;
		c.gridheight = 1;
		JSlider slider = new JSlider(1, 50,50);
		slider.setPaintLabels(true);
		Hashtable labelTable = new Hashtable();
		labelTable.put(new Integer(1), new JLabel("1"));
		labelTable.put(new Integer(10), new JLabel("10"));
		labelTable.put(new Integer(20), new JLabel("20"));
		labelTable.put(new Integer(30), new JLabel("30"));
		labelTable.put(new Integer(40), new JLabel("40"));
		labelTable.put(new Integer(50), new JLabel("50"));
		slider.setLabelTable(labelTable);
		inhalt.add( slider, c );

		c.gridx = 0;
		c.gridy = 2;
		c.gridwidth = 1;
		c.gridheight = 1;
		inhalt.add( new JButton("stop"), c );

		c.gridx = 2;
		c.gridy = 2;
		c.gridwidth = 1;
		c.gridheight = 1;
		inhalt.add( new JButton("start"), c );

		frame.setVisible(true);

	}
}

Mein Ziel:
In der Framemitte soll Java3D dargestellt werden.
Über der Java3D-Szene soll ein JSpinner sein.
Unter der Java3D-Szene soll ein JSlider sein.
Links und rechts neben dem JSlider soll jeweils ein JButton sein.

Problem:
Die Java3D Szene wird überhaupt nicht angezeigt

Hat jemand eine Idee??

Danke schonmal

Man musste einfach nur "fill" auf "GridBagConstraints.BOTH" setzen,
bevor ich die Java3D-Szene dem Frame hinzufüge.

// BEGIN JAVA3D
        c.fill= GridBagConstraints.BOTH;
        c.weightx = 100;
        c.weighty = 100;
        c.gridx = 1;
        c.gridy = 1;
        c.gridwidth = 1;
        c.gridheight = 1;
        GraphicsConfiguration config  		= SimpleUniverse.getPreferredConfiguration();
        Canvas3D canvas                    	= new Canvas3D(config);;
        inhalt.add(  canvas, c );
        SimpleUniverse universe            	= new SimpleUniverse(canvas);
        c.weightx = 1;
        c.weighty = 1;
        c.fill= GridBagConstraints.NONE;
        //END JAVA3D
