Can you add further actions to the Default X close operator

Is it possible to perform further actions when the 'X' button is pressed to close the screen. I would like it to carry over a value to another screen.

I believe you can do this in the window closed action listener. I would look into that. In a game my friends and i wrote we sent one last message to the server saying that the client left, and i believe we did it that way, code is on other laptop or i would check for you. but id look into that
