Python threading and GUIs

[John J Breen]

    Hey,
        Concerning threading in python I am trying to run two
GUI components with TK and GTK. I want them to communicate so I was
thinking of running the Tk mainloop in one thread and the GTK mainloop
in another. Can I not do this? Only the first thread that I start
actually runs and the second thread with the second GUI calls just seems
to be ignored.

Thanks
John
