Get the application closing event


How to get to the application closing event?

I want to get application to save all unsaved operations or show the user a message "Are you sure about closing without saving all data?" something like this.

If this will be helpful - the application is a SingleFrameAplication using Swing.


Solution

  • You could use a shutdown hook. It works for Swing, AWT and even console applications.

    Example:

    Runtime.getRuntime().addShutdownHook(new Thread()
    {
        @Override
        public void run()
        {
            //do your stuff
        }
    });
