JDialog close event ( ALT+F4 or clicking 'X' )

I have an applet that displays a modal JDialog. I need to capture the following two events :

1. The user presses ALT+F4 to close the dialog
-- OR --
2. The user clicks on "x" on the top right corner to close the dialog.

In either case, I need to do processing before the dialog is actually closed.

Please paste a code sample if you have any ideas.

Thanks.

Try this,

class myDialog extends JDialog{
myDialog(){
////
addWindowListener(new WindowAdapter(){
//capture the window closing event i.e clicking 'X'
public void windowClosing(WindowEvent evt){
///do any actions that u wish to
dispose();//dispose the JDialog
}
});
....
}

The steps are,
1. add a windowlistener to ur class. so that u can capture all the window events.
2. have an anonymous class declatarion for using windowadapter class.
3. capture teh windowClosing event.

Thanks for your suggestions. Even though both of them work fine, I have gone with the solution proposed by sgoms only because of the similarity to the code that I have for handling other events.

sgoms, I don't have a way of splitting any points, but I really really do appreciate your helping out.

Thanks a lot for your help.
