windowClosed() vs windowClosing()

windowClosed(): After window has closed.
windowClosing(): The process of being closed.

Which one is preferred for saving a state of an object using Properties? Does it matter? If one does windowClosing(), does he have to do setDefaultCloseOperation(WindowConstantsDO_NOTHING _ON_CLOSE) and then do either dispose() or System.exit(0)? That engenders another question: Is it better to do dispose(), System.exit(0), or both? There is only 1 frame in this app.

both as in:

Code:

---

dispose();
System.exit(0);

Thanks in advance!

Hmm, I just go through the documentation, windowClosed is "Invoked when a window has been closed as the result of calling dispose on the window." So that at the time of it's calling the window is gone. But windowClosing is called when it's gone, but well before it actually is. So my point it use of windowClosed.

If you System.exit(0) from windowClosing, any code in windowClosed will NOT be executed.

So should I do windowClosed() or windowClosing()? windowClosed() sounds like less work, but I want efficiency.

Okay windowClosed() sucks. The only way windowClosed() event is executed is when frame.setDefaultCloseOperation(javax.swing.JFrame. DISPOSE_ON_CLOSE) or you do dispose()

Should've listened lol. Just saw this. Sorry Eranga

This works for me:

frame.setDefaultCloseOperation(javax.swing.JFrame. EXIT_ON_CLOSE); + overriding windowClosing() event. No need to do dispose() or System.exit(0)

By mistake most of the people stuck on this unreachable code segment.

Yeah, avoiding dispose() is the most effective way to use in.
