It's a good idea, just not that reliable in practice. :-)

If I'm not collecting data from text widgets immediately,
I usually put off validating what is in them until the
user hits the Apply button, or whatever it is that sets
the operation off and makes me require good data. Then
I can do all my checking at once, and give the user
feedback if they need to do something different.

Cheers,

David
