    public MarqueeFrame() {

        Dimension d = Toolkit.getDefaultToolkit().getScreenSize();
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setSize(d.width,d.height);
        setTitle("HyperLink MARQUEE - Developed by TamizhVendan.S, Born to Win");
        setResizable(false);

        timer = new Timer(150, this);
        marqueePanel = new MarqueePanel(timer);
        add(marqueePanel);
        timer.start();
        
    }

    public static void main(String[] args) {
        new MarqueeFrame().setVisible(true);
    }

}

I use it at my application.
My needs are

1. want to add marquee panel at my application frame.
2.when I click menuitem,marquee texts will changes in a panel.
3.At that marquee panel has many JLabels with links

Here is my Marquee.java coding .It is the portion of my application.So you can't run it.So I am afraid to bore when you see my program. I am sorry for that.If possible ,pls help me.

        Rectangle r = new Rectangle();
        //r.setSize(300, 20);
        r.x=xLoc;
        r.y=yLoc;
        Dimension size;
        int count = 0;
        for(int i=0;i< -(count-1000))
            xLoc = 2500;
        System.out.println("x Location = "+xLoc);
    }
    public int getxLocation()
    {
        return xLoc;
    }
  }

My problems are

1.Marquee text's movement more quick,when I click a menuitem one times and one times.
2.When I resize my frame,frame expands as much as Marquee text's length has.My marquee text is very very long.May be nearly 4000 width of text.(At that time ,I can't resize my frame)

Thank in advance.
