[SOLVED] Not dispose my JPanel

[Eranga]

Hi all,

I've write some code to rendering some HTML code in a GUI. Here it is,

Code:

    private JEditorPane editor = new JEditorPane();
    private JPanel mainPanel = new JPanel();
    private JButton exitButton = new JButton();
    private JDialog mainDialog = new JDialog();

    private HTMLRendering(String htmlText){
        editor.setEditorKit(new HTMLEditorKit());
        editor.setContentType("text/html");
        editor.setBorder(new BevelBorder(BevelBorder.LOWERED));
        editor.setEditable(false);
        editor.setText(htmlText);    // HTML code should be added here
        editor.addHyperlinkListener(this);
        
    // Exit button
        exitButton.setText("Exit");
        exitButton.setSize(new Dimension(65, 25));
        exitButton.setLocation(185, 215);
        exitButton.setBorder(new BevelBorder(BevelBorder.RAISED));
        editor.add(exitButton);
        exitButton.addActionListener(new AbstractAction() {
            public void actionPerformed(ActionEvent e) {
                if("Exit".equals(e.getActionCommand())){  // Newly added code segment
                    System.out.println("Exit clicked");
                    mainDialog.dispose();
                }
            }
        });

        
        
    // Main panel
        mainPanel.setLayout(new BorderLayout());
        mainPanel.setPreferredSize(new Dimension(260, 250));
        mainPanel.add(editor);
    }
    
    private JPanel GetMainPanel(){
        return mainPanel;
    }
    
    public void CreateAndShowGUI(String htmlText){
        mainDialog.getContentPane().add(new HTMLRendering(htmlText).GetMainPanel());
        mainDialog.setResizable(false);
        //mainDialog.setUndecorated(false); // Changed in future
        mainDialog.pack();
        setWindowLocation();
        mainDialog.setVisible(true);
    }

My question is that, on the click event mainPanel is not dispose. Only I want to dispose, not exist the system. I can exit from the system, not the dispose which I want to do.

You guys have any idea why is that happened?

Thanks
