Ada Java question

[Kendal Van Dyke <kendal@fn3.freenet.tlh.fl.us>]

I am trying to redefine the keyDown event so that I can do something
when an arrow key is pressed while an applet is running, but I seem to
be having a problem when I compile  - it's giving me errors saying that
"Direct name, event, is not visible"

Here is my code. What's wrong with it?

  function keyDown(obj : access tank_obj;

  		   e : event_ptr;

  		   key : Integer) return boolean is

  begin

    CASE key IS

      WHEN event.UP => return true;

      WHEN event.DOWN => return true;

      WHEN event.LEFT => return true;

      WHEN event.RIGHT => return true;

      WHEN Others => return true;

    end CASE;  

    return true;

  end keyDown;

Any help is of course much appreciated!
