Hi All,
I am using a Frame and from this frame i am calling the JFileChooser via a JButton.
and using JFileChooser ShowOpenDialog() for open and close .
while doing ESC operation my Main Frame is getting closed with JFileChooser dialog.
Can i close only JFileChooser dialog while doing ESCAPE key operation.
I Have Escape key function in Main Frame file and JFileChooser file( EscKeyEventActionIntialization)
But while debuging i am not able to catch the esc key action inside EscKeyEventActionIntialization.
I have attached the code, please suggest me , if i need to do any change .

    private void EscKeyEventActionIntialization()
        Action  ESCactionListener = new AbstractAction () {
          public void actionPerformed(ActionEvent actionEvent) {
            dialog.setVisible(false);
            dialog.dispose();
        KeyStroke stroke = KeyStroke.getKeyStroke(KeyEvent.VK_ESCAPE, 0, true);
        JComponent comp = dialog.getRootPane();
        comp.getInputMap(JComponent.WHEN_IN_FOCUSED_WINDOW).put(stroke, "ESCAPE");
        ActionMap actionMap = comp.getActionMap();
        actionMap.put("ESCAPE", ESCactionListener);
}

You have a class that extends JDialog and has a JDialog member variable (very confusing), and no main(...) method. How is the class used as a JDialog?
To get better help sooner, post a SSCCE that clearly demonstrates your problem. Note that this should be executable and should not contain any extraneous code.
