Using NEWT the window flashes and then the program terminates.

Hello everyone, I have been trying out the tutorials on https://sites.google.com/site/justinscsstuff/jogl-tutorial-2 and I have opted for the NEWT approach after seeing the comparison in the wiki regarding the performance. The AWT example SimpleScene provided work fine and it can be debugged. Trying the NEWT SimpleScene class thow actualy is giving a problem. The program compiles fine, the threads are started and then it all shuts down, while in the AWT version the window stays up until I close it. Please see details in the video below: http://youtu.be/KbR2-QBTJGw

I know this tutorial https://sites.google.com/site/justinscsstuff/jogl-tutorial-2 works fine from experience.

I say double check your code. Or show it here.

The code is exactly the same as it is at the moment on the justincstuff site.

Simple copy and paste, although it is not visible in the video since I used Ctrl+C/V for getting it rather than the context menus.

The weird thing is that using the TestGearsNEWT.java as referenced from the NEWT Overview page (adapting slightly the class layout to work standalone) makes everything work properly. I don't know why the only new thing in that class is the usage of the Animator object...

Unlike AWT, creating a NEWT Window does not stop the JVM from being closed!

To do so, you either need to manually keep the main thread alive,
or - like many of the NEWT demos - keep another non daemon thread alive,
like the Animator.

Sven thanks a lot for clearing this up. *bows*
