Hi,

I'm having problems in adding a picture into JFrame, something is missing probebly or written wrong. here are the classes:

main class:

public class Tester

    {
        public static void main(String args[])
        {
            BorderLayoutFrame borderLayoutFrame = new BorderLayoutFrame();
            borderLayoutFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
            borderLayoutFrame.setSize(600,600);
            borderLayoutFrame.setVisible(true);
        }
    }

public class BorderLayoutFrame extends JFrame implements ActionListener 
 {
     private JButton buttons[]; // array of buttons to hide portions
     private final String names[] = { "North", "South", "East", "West", "Center" };
     private BorderLayout layout; // borderlayout object
     private PicPanel picture = new PicPanel();

     // set up GUI and event handling

     public BorderLayoutFrame()
     {
         super( "Philosofic Problem" );
         layout = new BorderLayout( 5, 5 ); // 5 pixel gaps
         setLayout( layout ); // set frame layout
         buttons = new JButton[ names.length ]; // set size of array

         // create JButtons and register listeners for them

         for ( int count = 0; count < names.length; count++ ) 
         {
             buttons[ count ] = new JButton( names[ count ] );
             buttons[ count ].addActionListener( this );
         }
         add( buttons[ 0 ], BorderLayout.NORTH ); // add button to north
         add( buttons[ 1 ], BorderLayout.SOUTH ); // add button to south
         add( buttons[ 2 ], BorderLayout.EAST ); // add button to east
         add( buttons[ 3 ], BorderLayout.WEST ); // add button to west
         add( picture, BorderLayout.CENTER ); // add button to center
    }

    // handle button events

    public void actionPerformed( ActionEvent event )
    {

    } 

  }

I'v tried to add the image into the center of layout.

here is the image class:

public class PicPanel extends JPanel
{
    Image img;
    private int width = 0;
    private int height = 0;

    public PicPanel()
    {
        super();
        img = Toolkit.getDefaultToolkit().getImage("table.jpg");
    }
    public void paintComponent(Graphics g)
    {
         super.paintComponents(g);
         if ((width <= 0) || (height <= 0))
         {
             width = img.getWidth(this);
             height = img.getHeight(this);
         }
         g.drawImage(img,0,0,width,height,this);
    }
}

Please your help, what is the problem? thanks

BTW: i'm using eclipse, which directory the image suppose to be in?
