3f4e014 by Guy Harris (guy@xxxxxxxxxxxx):

    Check the validator in ExtArgText::isValid().
    
    The validator doesn't prevent the input focus from being transferred out
    of the QLineEdit, and it merely prevents the user from entering a value
    that's considered "invalid" rather than "not valid but "intermediate"".
    
    For QIntValidator(), values that have more digits than the maximum value
    are "invalid", but values that have the same number of digits but that
    are larger are just "intermediate".
    
    This means the user will be able to send such a value to the extcap
    module.
    
    So we explicitly check the validator in ExtArgText::isValid(), so that
    1) we provide visual feedback (at least to people who can detect a red
    background) for out-of-range values that don't have too many digits and
    2) prevent them from being treated as valid and passed to the extcap
    module.
