Cannot load image in constructor

[ValValVal]

Hi!
Please help with following question, this is really something I have not a clue why this is happening.

I want to display BufferedImage in my JFrame. Now I need to load images first from disk.

if I execute this code in constructor of the program and after try to paint
in my paint function then nothing is painted.
================
in constructor:

try {
    whitePawn = ImageIO.read(new File("c:\\finalbig\\pawnwhite.gif"));
} catch (IOException e) {System.out.println(" Cannot load images");}
 

in paint:

  g2d.drawImage(whitePawn, 0,30, this);

================

and if I put loading instruction in paint before drawImage() it works ok.
================
all in paint:

try {
    whitePawn = ImageIO.read(new File("c:\\finalbig\\pawnwhite.gif"));
} catch (IOException e) {System.out.println(" Cannot load images");}
 
  g2d.drawImage(whitePawn, 0,30, this);
 

===============

Variable whitePawn is a field.
If needed I can post more code.
Thanks in advance for answering my stupid question.

Is anything that effects any of the variables used done in between?

No,as far as I see nothing is done.
I use NetBeans 6.1.

This code draws picture:

package drawingpieces;
 
import java.awt.*;
import java.awt.event.*;
import java.io.*;
import javax.imageio.*;
import java.awt.image.*;
 
public class Example03 extends Frame {
 
    public BufferedImage whitePawn,  whiteKnight,  whiteBishop,  whiteRook,  whiteQueen,  whiteKing;
 
    public static void main(String args[]) {
        new Example03();
    }
 
    public Example03() {
        super("Java 2D Example03");
 
        setSize(500, 500);
        setVisible(true);
 
       /* try {
            whitePawn = (BufferedImage) ImageIO.read(new File("c:\\pawnwhite.gif"));
        } catch (IOException e) {
            System.out.println(" Cannot load images of the pieces");
        }*/
 
 
 
        addWindowListener(new WindowAdapter() {
 
            public void windowClosing(WindowEvent e) {
                dispose();
                System.exit(0);
            }
        });
    }
 
    public void paint(Graphics g) {
        Graphics2D g2d = (Graphics2D) g;
        g2d.setRenderingHint(RenderingHints.KEY_ANTIALIASING,
                RenderingHints.VALUE_ANTIALIAS_ON);
 
       try {
            whitePawn = ImageIO.read(new File("c:\\pawnwhite.gif"));
        } catch (Exception e) {
        }
 
        g2d.drawImage(whitePawn,200, 200, this);
 
    }
}

And this doesn't draw:

package drawingpieces;
 
import java.awt.*;
import java.awt.event.*;
import java.io.*;
import javax.imageio.*;
import java.awt.image.*;
 
public class Example03 extends Frame {
 
    public BufferedImage whitePawn,  whiteKnight,  whiteBishop,  whiteRook,  whiteQueen,  whiteKing;
 
    public static void main(String args[]) {
        new Example03();
    }
 
    public Example03() {
        super("Java 2D Example03");
 
        setSize(500, 500);
        setVisible(true);
 
        try {
            whitePawn = (BufferedImage) ImageIO.read(new File("c:\\pawnwhite.gif"));
        } catch (IOException e) {
            System.out.println(" Cannot load images of the pieces");
        }
 
 
 
        addWindowListener(new WindowAdapter() {
 
            public void windowClosing(WindowEvent e) {
                dispose();
                System.exit(0);
            }
        });
    }
 
    public void paint(Graphics g) {
        Graphics2D g2d = (Graphics2D) g;
        g2d.setRenderingHint(RenderingHints.KEY_ANTIALIASING,
                RenderingHints.VALUE_ANTIALIAS_ON);
 
 
 
        g2d.drawImage(whitePawn,200, 200, this);
 
    }
}

Make that 'setVisible(true)' statement the last statement of your constructor
when everything is properly initialized (so the images aren't null anymore).

kind regards,

Thanks VERY much. It works now!
