Hi A. Murat
Well, I think the code below can help you.
import java.awt.event.*;
import java.util.*;
import javax.media.j3d.*;
import javax.vecmath.*;
import javax.swing.*;
import com.sun.j3d.utils.universe.*;
public class Example extends JFrame
{
public Example()
{
addWindowListener(new WindowAdapter() {
public void windowClosing(WindowEvent e) {
dispose();
System.exit(0);
}
});
JButton b1 = new JButton("Behavior");
getContentPane().setLayout(null);
getContentPane().add(b1);
b1.setBounds(10,10,100,50);
final SimpleUniverse su = new SimpleUniverse();
b1.addActionListener(new ActionListener()
{
public void actionPerformed(ActionEvent e)
{
ButtonBehavior bBehavior = new
ButtonBehavior(su.getViewingPlatform().getViewPlatformTransform());
bBehavior.setSchedulingBounds(new BoundingSphere(new
Point3d(0.0,0.0,0.0),Double.POSITIVE_INFINITY));
BranchGroup branchBehavior = new BranchGroup();
branchBehavior.addChild(bBehavior);
su.getLocale().addBranchGraph(branchBehavior);
}
});
}
public static void main(String args[])
{
Example mainFrame = new Example();
mainFrame.setSize(130,90);
mainFrame.setTitle("Example");
mainFrame.setVisible(true);
}
}
class ButtonBehavior extends Behavior
{
TransformGroup tg;
Transform3D c = new Transform3D();
WakeupCriterion actionEvent;
public ButtonBehavior(TransformGroup transformGroup)
{
tg = transformGroup;
}
public void initialize()
{
actionEvent = new
WakeupOnBehaviorPost(this,MouseEvent.MOUSE_CLICKED);
postId(MouseEvent.MOUSE_CLICKED);
wakeupOn(actionEvent);
}
public void processStimulus(Enumeration criteria)
{
System.out.println("It's working...");
wakeupOn(actionEvent);
}
}

Hi Alessandro,
Thanks for your reply,
I understand that my use of switch is not the correct way. I will change
it according to your advices. However, my question is how I can link my
behaviour with the JButton event so that the cubes are woke up when I
press the button? At the moment the cubes woke up 3 seconds after the
scene construction.
I think I have to have two criteria for this; first is the elapsed time
the other is the press event of the JButton. But how can I detect that
the particular Button is pressed?
Regards,
Murat
