Frågan#1

Jag har ett program som den ena filen ritar pilar och de andra filen ritar boxar som man kan flytta och rotera runt.

Problemet ligger i den andra filen alltsa klassen GraphicArrow, dess addMouseListener vill inte fungera nar jag klickar pa musen, kan nagon tala om vad det ar som ar fel?

Har kommer koden:
klassen GraphicArrow

   public GraphicArrow() {
      arrow.moveTo(-20, -10);
   }

      arrow.lineTo(-20, -10);

      xA = x;
      yA = y;

      addMouseListener(new MouseAdapter()
      {
         Rectangle hitRect = new Rectangle(0, 0, 5, 5);

         public void mouseClicked(MouseEvent e)
         {
            Graphics2D g = (Graphics2D) getGraphics();
            AffineTransform xform = new AffineTransform();

            // puts hit rectangle 2 pixels around click point
            hitRect.x = e.getX() - 2;
            hitRect.y = e.getY() - 2;

            Rectangle bounds = arrow.getBounds();

            if (g.hit(hitRect, arrow, false))
                System.out.println("Traff i pilen ");
         }
      });
    }

   public void paintComponent(Graphics _g) 
   {
      super.paintComponent(_g);
      Graphics2D g = (Graphics2D) _g;

      // Translates and rotates the arrow
      g.translate(xA, yA);
      g.rotate(Math.PI / 1);

      // Fills and outlines the arrow
      g.setPaint(gradientPaint);
      g.fill(arrow);
      g.setPaint(Color.BLACK);
      g.draw(arrow);

      // Translates and rotates back to normal
      g.rotate(Math.PI / -1);
      g.translate(-xA, -yA);
   }

   public static void main(String args[]) {
      JFrame frame = new JFrame("Arrow");
      frame.getContentPane().add(new GraphicArrow());
      frame.setBackground(Color.white);
      frame.setSize(new Dimension(400, 350));
      frame.setLocationRelativeTo(null);
      frame.setVisible(true);
    }
