Hello tutors, I experience problems with signal handlers, and the explanatzions in the docs don't seem to help me much.
The code I try to handle basically comes down to this (it's supposed to run on linux only, btw): from Tkinter import * import tkSnack root = Tk() tkSnack.initializeSnack(root) root.mainloop() initializeSnack() tries to access the sound device, however if this fails it tries forever and doesn't return. I *thought* a signal handler might be what I need, and in fact it partially works, at least initializeSnack() is stopped when I add this: from Tkinter import * import tkSnack, signal root = Tk() signal.signal(signal.SIGALRM, signal.getsignal(signal.SIGALRM)) signal.alarm(5) tkSnack.initializeSnack(root) signal.alarm(0) root.mainloop() Now when the audio device is busy, after 5 seconds the app prints "Alarm clock" and exits. However I would prefer to have a more controlled exit, but as soon as I define a custom signal handler it's the same as before - it never gets called. Any help is much appreciated Michael _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
