I want to draw an image at X Y position when the user click the mouse
so I'm using an InternalFrame with layout set to NULL , inside a JFrame with Layout free - using netbeans
here is the image class

package myPak_1;
import java.awt.*;
import java.awt.image.*;
import java.io.*;
import javax.imageio.*;
public class Images extends Component{
    BufferedImage img;
    public void paint(Graphics g) {
        g.drawImage(img, 0, 0, null);
    }
    public Images() {
       try {
           img = ImageIO.read(new File("C:\\Users\\Ibrahim\\Documents\\NetBeansProjects\\Info306_prev_1\\src\\myPak_1\\state1.png"));
       } catch (IOException e) {
       }
    }
    public Dimension getPreferredSize() {
        if (img == null) {
             return new Dimension(100,100);
        } else {
           return new Dimension(img.getWidth(null), img.getHeight(null));
       }
    }
}

and here is the JFrame

package myPak_1;
public class MainWindow extends javax.swing.JApplet {

    /** Initializes the applet MainWindow */
    public void init() {
        try {
            java.awt.EventQueue.invokeAndWait(new Runnable() {
                public void run() {
                    initComponents();
                }
            });
        } catch (Exception ex) {
            ex.printStackTrace();
        }
    }

}

private void jInternalFrame1MouseClicked this is the method where i'm trying to do the job
i'm following this tutorial
http://download.oracle.com/javase/tutorial/uiswing/layout/none.html
"If a container holds components whose size is not affected by the container's size or by font, look-and-feel, or language changes, then absolute positioning might make sense. Desktop panes, which contain internal frames, are in this category"

Okay? And your problem is ...?

I forgot to say what is my problem ;)
The image wasn't drawn in the internal frame on mouse click
but the problem is solved now , I corrected the parameters of setBounds()
