I've trouble with actionListener. I created own simple dialog, which has only two JButtons - Yes and No. When I click on button, actionListener doesn't respond.

This is my code:

private void showInfoNewUML() {        
    Dimension buttonsSize = new Dimension(60, 25);
    Dimension programSize = new Dimension(1200, 700);
    final JDialog dialogWindow = new JDialog(this, "Erase actual UML diagram"
            + " with his files", true);        
    JTextArea descDialogWindow = new JTextArea("Do you really erase actual\n"
            + "UML diagram with his files?   ");
    descDialogWindow.setEditable(false);
    descDialogWindow.setBackground(new Color(220, 220, 220));
    descDialogWindow.setBorder(null);
    dialogWindow.getContentPane().setBackground(new Color(220, 220, 220));
    dialogWindow.setDefaultCloseOperation(DISPOSE_ON_CLOSE);
    dialogWindow.setModal(true);
    dialogWindow.setResizable(false);
    dialogWindow.setLayout(new FlowLayout());
    dialogWindow.setSize(310, 100);
    dialogWindow.setLocation((int) programSize.getWidth() / 2,
            (int) programSize.getHeight() / 2);
    JButton buttonYes = new JButton("Yes");
    JButton buttonNo = new JButton("No");
    buttonYes.setPreferredSize(buttonsSize);
    buttonNo.setPreferredSize(buttonsSize);
    dialogWindow.add(descDialogWindow);
    dialogWindow.add(buttonYes);
    dialogWindow.add(buttonNo);
    dialogWindow.setVisible(true);

    buttonYes.addActionListener(new ActionListener() {

        @Override
        public void actionPerformed(ActionEvent e) {
            buttonAnoActionPerformed(e);
        }

        private void buttonAnoActionPerformed(ActionEvent e) {
            dialogWindow.setVisible(false);
        }
    });

    buttonNo.addActionListener(new ActionListener() {

        @Override
        public void actionPerformed(ActionEvent e) {
            buttonNeActionPerformed(e);
        }

        private void buttonNeActionPerformed(ActionEvent e) {
            dialogWindow.setVisible(false);
        }
    });
}

I would like close this dialog after I click on button. When I click to top right button with cross, dialog window closes.

Thank you for help with this trouble.

• jbutton
• actionlistener

Try adding the ActionListeners before calling dialogWindow.setVisible(true);.

Your dialog is modal, and so showInfoNewUML will block at dialogWindow.setVisible(true); until after the dialog is closed, which is too late to register any useful listeners.
