Right method to exit/dispose on linux

So, to sum up and understand, why does it work with the animator? Because is it itself a thread that keeps the application running?

The Animator execution thread does not run as a daemon thread, so it is able to keep an application from terminating.

I don't know exactly what the daemon attribute means, however, let me get it, so basically this means that we end up having both the main thread and the animator thread running where the only things that prevents the main from terminating is the animator itself.

This also would mean that in order to quit properly, I just have to terminate (stop?) the animator and then the main will terminate as well?

Just try my example, as far as I can tell it does exactly what you are asking for

It takes a little while for the main thread to stop because of the internal clean up but the application will exit cleanly, no need for any System.exit calls or anything. Just close the window by clicking the close button and wait a few seconds.

:) I tried that, jmaasing, but I got this warning in the console (on the window closing)

Thread[main-Display-.windows_nil-1-EDT-1,5,main]: Warning: Default-EDT about (2) to stop, task executed. Remaining tasks: 1 - Thread[main-Display-.windows_nil-1-EDT-1,5,main]

Is that normal?

That's why I actually wanted also to understand the complete interaction between the main and the animator

Ps: i just modified your code by adding "final" to the animator declaration

I haven't seen that warning but I use OSX so I'm not sure if it is normal on other platforms. I don't understand what it is warning about. Maybe some one can enlighten us.

Way to go with "final" - I usually write final on everything but removed it in the example to make it look cleaner :-)

When using Java Webstart, you're still forced to call System.exit(0) as far as I know.

Yep, that solved.

Thanks you all, guys

I wish the forum had a flag to "report content as appropriate"  I learn something new every day.

So, I tried to port the method to my program, adding the glViewer to a JFrame

But I still get
