JMEDesktop inside an applet

Troubleshooting General Help

I am trying to run the HelloJMEDesktop.java example, but inside a SimpleJMEApplet. I can't make this work, when I click the button it throws a thread related exception:

Sounds like JMEDesktop should check whether its in the EventDispachThread before calling invokeAndWait.



Something like:



Runnable toRun = new Runnable() {
     public void run() {
          // the code to run in the EventDispatchThread
     }
}

if ( SwingUtilities.isEventDispatchThread() )
     toRun.run();
else
     SwingUtilities.invokeAndWait( toRun );
