As an alternative (slight change to behaviour) you could hook up to the 
"on change" signals of the text fields, and set the OK button's 
sensitivity according to their new contents. Thus the OK button would be 
greyed out until it's valid to press. It's a bit more work but some 
might think it's a nicer user interface.
