---- Reported by daw 2004-01-17 22:28:27 ----

When adding multiple panels into a frame where components do not overlap, the 
GLCanvas occupies the entire frame, drawing over the other panels under Mac OS X.  The 
problem does not appear to exist under Linux.  An example is included below.  On MacOS 
X (10.2.8), the buttonPanel is not visible, however, under Linux, the buttonPanel is visible.

------- Test Program --------

import net.java.games.jogl.*;
import javax.swing.*;
import java.awt.*;

public class TestProgram {
  private static class Renderer implements GLEventListener {
    public void display( GLDrawable drawable ) {
      GL gl = drawable.getGL();
      gl.glBegin( GL.GL_TRIANGLES );
      gl.glVertex2d(-1.0, -1.0 );
      gl.glVertex2d(1.0, -1.0);
      gl.glVertex2d(0.0, 1.0);
    public void displayChanged(GLDrawable drawable, boolean modeChanged, 
                             boolean deviceChanged) { }
    public void init(GLDrawable drawable) {}
    public void reshape( GLDrawable drawable, int x, int y, int w, int h){
      GL gl = drawable.getGL();
      gl.glOrtho(-2.0, 2.0, -2.0, 2.0, -1, 1 );
  public static void main( String[] args ) {
    JFrame frame = new JFrame();
    JPanel mainPanel = new JPanel();
    mainPanel.setLayout( new BorderLayout() );
    Renderer rend = new Renderer();
    GLCanvas can = GLDrawableFactory.getFactory().createGLCanvas(new 
    can.addGLEventListener( rend );
    mainPanel.add(can, BorderLayout.CENTER );
    JPanel buttonPanel = new JPanel();
    buttonPanel.add( new JButton("Button One") );
    buttonPanel.add( new JButton("Button Two") );
    mainPanel.add(buttonPanel, BorderLayout.SOUTH);
    frame.setSize( 400,400);

This is working for me.

You need to either get the 1.4.2 DP2 (or the final when it is released), or install Java3D on top of 
JDK1.4.1. Java3D comes with updated libjawt.dylib which is where the problem was.
