Generating an event in Tkinter

[nharlow at my-deja.com]

This is the code I am now using.  However, now the window is just
freezing entirely.  It is not executing the print statement.  None of
the other buttons will work.  It just locks up; I don't even get any
errors.  Any other ideas?


import time
name="Analyze"
while i< 100:
	print "%s: This is %s time through the loop"%(name,i+1)
	widget.event_generate("<<foo>>")
	widget.bind("<<foo>>", lambda e, y=1, x=time.sleep: x(y))
	i=i+1
