Re: picking and mouse events

Hit "send" too quickly.  Meant to put in this example:

In you 'parent frame', do this:

0)  import java.awt.event.*;
1)  public class ParentFrame implements ActionListener ...
2)  VisADThing vat = new VisADThing(....);
    vat.addActionListener(this);
    ...
    public void actionPerformed(Event e) {
    // do your stuff
    }

In your VisADThing:

0)  import java.awt.event.*;
1)  ActionListener al = null;
2)  public void addActionListener(ActionListener a) {
      al = a;
    }
3)  in 'doAction()' ...

    if (al != null) al.actionPerformed(
        new ActionEvent(this, "what happened", 0));
