Java: Disable the X close button

BrokenArrows

How can i disable the X close button in my JFrame.

I want my users to exit using a button supplied. Or if it is possible call a piece of code when the user hits the X button.

I would rather use Disable the X button.

I know i can use

this.setDefaultCloseOperation(WindowConstants.DO_NOTHING_ON_CLOSE);

But this does not fade the button

Hi. I am only familiar with frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); But i guess if you omit this, then it will not close when you click the x button. Why do you wish to do this anyway?

heres how to perform code when user click X to close.
this does a standard do you want to close dialog.

final JFrame f = new MyFrame();
f.setDefaultCloseOperation(JFrame.DO_NOTHING_ON_CLOSE);
f.addWindowListener(new WindowAdapter(){
   public void windowClosing(WindowEvent e){
      int n = JOptionPane.showConfirmDialog(f,"Do you want to close Application?","Close Application",JOptionPane.YES_NO_OPTION);
      if(n == 0){
         LogOffRequest.doIt(back[1]);
         System.exit(0);
      }
   }
});

You could use a JDialog instead of a JFrame
