joptionpane

So, I've read the Java API, but still can't seem to make heads or tails about how to do this. And believe me I have tried. I want an ActionListener to cause a message box with the text 'Do you really want to exit?', with options yes and no which exits the program or not depending on the selected button. Here's what I have for the ActionListener before I started to break it with the message box: exitItem.addActionListener( new ActionListener() { public void actionPerformed(ActionEvent arg0) { window.dispose(); } } ); How can I suitably change it to meet my requirements?

Here is my current code: JFileChooser chooser = new JFileChooser() { public void approveSelection() { File selectedFile = getSelectedFile(); if (selectedFile != null && selectedFile.exists( ) ) { int response = JOptionPane.showConfirmDialog( this, "The file " + selectedFile.getName() + " already exists." + " Do you want to replace the existing file?", getDialogTitle(), JOptionPane.YES_NO_OPTION, JOptionPane.WARNING_MESSAGE); if (response

I have problem currently for my swing reminder application, which able to minimize to tray on close. My problem here is, I need JOptionPane dialog to pop up on time according to what I set, but problem here is, when I minimize it, the dialog will pop up, but not in the top of windows when other application like explorer, firefox is running, anyone know how to pop up the dialog box on top of windows no matter what application is running? Walter Create an empty respectively dummy JFrame, set it always on top and use it as the component for the JOptionPane instead of null. So the JOptionPane

I have added JOptionPane to my application but I do not know how to change background color to white? `int option = JOptionPane.showConfirmDialog(bcfiDownloadPanel, new Object[]{"Host: " + source, panel}, "Authorization Required", JOptionPane.OK_CANCEL_OPTION, JOptionPane.PLAIN_MESSAGE ); if (option == JOptionPane.OK_OPTION) { }` By using the UIManager class import javax.swing.UIManager; UIManager UI=new UIManager(); UI.put("OptionPane.background",new ColorUIResource(255,0,0)); UI.put("Panel.background",new ColorUIResource(255,0,0)); or UIManager UI=new UIManager(); UI.put("OptionPane
