panel and image problem

[alun groome]

hi,

I basically have 2 problems now. Firstly the image doesnt appear on the Panel unless I resize the window, and when i move the dialog box off the screen, the image gets erased. similar to the eraser in paintbrush. I have tried doing repaint() and nothing.

And finally, the functionality is lost in the main frame when i close the dialog box

please help!!

thanks

This is a code snippet from the JFRAME that calles the dialog

class ButtonActionListener
implements ActionListener {
public void actionPerformed(ActionEvent event) {

DialogBox dialog = new DialogBox (frame, true);
dialog.setSize(100,100);
dialogsetVisible(true);



}
}

This is a snippet of the dialog. I have called this class DialogBox

private void buildGui() {

GridBagConstraints gc = new GridBagConstraints();

Container c = this.getContentPane();

c.setLayout(new GridBagLayout());

this.setDefaultCloseOperation(WindowConstants.DISPOSE_ON_CLOSE);


ImageIcon image;

String image= getPic(1);


ImageIcon icon = new ImageIcon(getClass().getResource(image));

JLabel iconLabel;

iconLabel = new JLabel(icon);

JPanel panel = new JPanel();

panel .add(iconLabel, BorderLayout.NORTH);
JButton button = new JButton("Answer");
gc.gridx = 0;
gc.gridy = 0;

c.add(panel , gc);

gc.gridx = 0;
gc.gridy = 1;
gc.ipady = 0;

c.add(button, gc);


this.pack();

}

        Image image = icon.getImage();
        Dimension d = new Dimension(image.getWidth(panel), image.getHeight(panel));
        //System.out.println("d = " + d.toString());
        panel.setPreferredSize(d);
        panel.add(iconLabel, BorderLayout.NORTH);
 
        JButton button = new JButton("Answer");
        gc.gridx = 0;            // these 4 lines are
        gc.gridy = 0;            // default values
        c.add(panel , gc);
 
        gc.gridx = 0;            // and therefore
        gc.gridy = 1;
        gc.ipady = 0;            // are not needed
        c.add(button, gc);
