Detailed Description

If the other field specified as otherField does not contain any of the values specified in the otherValues list, the field under validation must be present and not empty. This validator is the opposite of ValidatorRequiredIf.

Note
Unless validation is started with NoTrimming, whitespaces will be removed from the beginning and the end of the input value before validation. So, fields that only contain whitespaces will be treated as empty.
Return type
On success, ValidatorReturnType::value will contain a QString.

Validator for general usage of validators.

Member Function Documentation

◆ genericValidationError()

QString ValidatorRequiredUnless::genericValidationError ( Context * c,
const QVariant & errorData = QVariant() ) const
overrideprotectedvirtual

Returns a generic error message if validation failed.

◆ validate()

◆ validateCb()

void ValidatorRequiredUnless::validateCb ( Context * c,
const ParamsMultiMap & params,
ValidatorRtFn cb ) const
overrideprotectedvirtual

Performs the validation on the input params and calls the cb with the ValidatorReturnType as argument.

If validation succeeded, ValidatorReturnType::value will contain the input paramter value as QString.
