JFrame father = new JFrame();
final JLabel mainlable;


ImageIcon iconBigMAIN = new ImageIcon("GBIC-empty-new.gif");




final JPanel buttonPanel = new JPanel();


father.setSize(410,250);
father.setLocation(50,50);
buttonPanel.setSize(410,250);
buttonPanel.setLayout(null);
mainlable = new JLabel(iconBigMAIN);
buttonPanel.add(mainlable);
mainlable.setBounds(50,50,300,33);
father.getContentPane().add(buttonPanel);

MouseListener mouse = new MouseListener()
{
public void mouseEntered( MouseEvent e )
{
}

public void mouseExited( MouseEvent e )
{
}

public void mousePressed( MouseEvent e )
{
mainlable.repaint();
}
public void mouseReleased( MouseEvent e )
{
}

public void mouseClicked(MouseEvent e)
{

if(e.getSource() == mainlable)
{

Graphics grjp = mainlable.getGraphics();
System.out.println("KKKKKKKKKKKKK 0");
grjp.setColor(Color.yellow);
grjp.fillRect(60,60,100,10);
System.out.println("KKKKKKKKKKKKK 1");

}
}
};

mainlable.addMouseListener(mouse);

father.setVisible(true);
}
}

grjp.fillRect(60,60,100,10);
改一下
如grjp.fillRect(60,60,100,100);

如果是显示边框的话最好用grjp.drawRect
