Keep in mind that in the __init__ method the window most likely is not 
even visible yet (because the parent frame probably isn't shown yet) so 
sleeping and changing values there will not be able to be seen at all. 
Secondly, you should not us sleep for timing things like this, use a 
timer and events instead.  In other words, give the widget your initial 
value, create and start a timer and bind a handler to the timer event, 
and then continue with the normal startup.  Then in the timer event 
handler you can just change the value of the widget.
