OK. It would help me if the example was in readable Python for a start...
Am I right in thinking it would translate as
root.after_idle(foo)
def foo():
.....
root.after(0, foo)
In this case I'm even more confused. What's the point of it being an
"idle event"
the first time but never thereafter? Wouldn't it be equivalent to also
add it the
same way the first time?
Thanks,
Geoff
