[Jython-users] Interpreter won't exit normally after making a java.awt.Frame !??

[J S. I. <xy...@ke...>]

I don't get it. If I instantiate a Frame, it never goes away and holds up
the interpreter from exiting.  In the simplest case:

  import java
  java.awt.Frame(visible=1)

The interpreter will not exit.  I have tried several things:

  import java
  def close(x): x.source.dispose()
  f=java.awt.Frame(visible=1, windowClosing=close)

I close the window, set f=None, exit the interpreter.. it still hangs.

  import javax
  f=javax.swing.JFrame(visible=1)

...still hangs on exit.  Incidentally, this also happens when running the
script from a file.

Does anyone else get this problem?


Jython 2.1 on JDK1.3 (also on jview 5.00.3310) on Win2000.

Yes, I also have this problem under similar circumstances with awt and 
swing. I'm running Jython 2.1 using JDK1.3 on Red Hat Linux 6.2.

How do you "exit the interpreter"?

If you don't call "sys.exit()" or "java.lang.System.exit()" then the
AWT_EventQueue thread is still running (and it isn't a daemon thread)
so the app won't quit.  Normally you will add an event handler to the
closing of the window that calls exit().  (Normally main() returns
long before the program is done running)
