<DIV>Hi Ian,</DIV>
<DIV> </DIV>
<DIV>I had some trouble doing something like this when I was trying to write a balloon widget. I was using while, threading, etc... Try changing your act() method to this:</DIV>
<DIV> </DIV>
<DIV> def act(self):<BR> self.ring = self.stringv.get()+self.stringv2.get()+":"\<BR> +self.stringv3.get()+self.stringv4.get()<BR> self.track = [None]<BR> self.c = self.clock()<BR> self.stringv.set(self.c[0])<BR> self.stringv2.set(self.c[1])<BR> self.stringv3.set(self.c[3])<BR> self.stringv4.set(self.c[4])<BR> <BR> <BR> self.c = self.clock() <BR> if self.c !=
self.ring:<BR> if self.c == self.track[-1]: pass<BR> else:<BR> self.stringv.set(self.c[0])<BR> self.stringv2.set(self.c[1])<BR> self.stringv3.set(self.c[3])<BR> self.stringv4.set(self.c[4])<BR> self.track.append(self.c)<BR> else: winsound.PlaySound("rooster.wav", winsound.SND_LOOP)<BR>
<BR> self.master.after(1000, self.act)</DIV>
<DIV> </DIV>
<DIV>Tk().after(milliseconds, method/function to call) is great for this sort of thing.</DIV>
<DIV> </DIV>
<DIV>Good luck!</DIV>
