In addition to Stef's recommendation, the correct approach to this is to use value converters and a mixture of flags on the widgets (e.g. numeric-only) and closures for validation. That way, the widgets "think" in text, and the ultimate model (or aspect thereof) can have whatever type is appropriate to the domain.
