NEWT Utility class MainThreadFIXME: Update this documentation! This class just provides a main-thread utility, forking of a main java class on another thread while being able to continue doing platform specific things on the main-thread. The latter is essential for eg. MacOSX, where we continue to run NSApp.run().
This class provides a startup singleton main thread, from which a new thread with the users main class is launched.
Such behavior is necessary for native windowing toolkits, where the windowing management must happen on the so called main thread e.g. for Mac OS X !
Utilizing this class as a launchpad, now you are able to use a NEWT multithreaded application with window handling within the different threads, even on these restricted platforms.
To support your NEWT Window platform, you have to pass your main thread actions toinvoke(..)
, have a look at theNEWT Mac OSX Window
driver implementation.
TODO: Some hardcoded dependencies exist in this implementation, where you have to patch this code or factor it out.If your platform is not Mac OS X, but you want to test your code without modifying this class, you have to set the system property
newt.MainThread.force
totrue
.The code is compatible with all other platform, which support multithreaded windowing handling. Since those platforms won't trigger the main thread serialization, the main method will be simply executed, in case you haven't set
newt.MainThread.force
totrue
.Test case on Mac OS X (or any other platform):
java -XstartOnFirstThread com.jogamp.newt.util.MainThread demos.es1.RedSquare -GL2 -GL2 -GL2 -GL2
Which starts 4 threads, each with a window and OpenGL rendering.
