Detailed Description

If the stash content identified by stashKey does not contain any of the values specified in the stashValues list, the field under validation must be present and not empty. stashValues can contain a QString, a QStringList or a QVariantList. If it is a QString, it is interpreted as a stash key that contains the comparison list, that has to be either a QStringList or a QVariantList. If stashValues or the content of the there specified stash key is a QStringList, the content of stashKey will be converted into a QString to compare. If stashValues or the content of the there specified stash key is a QVariantList, the variants will be compared.

This validator ist the opposite of ValidatorRequiredIfStash and is similar to ValidatorRequiredUnless.

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.

Constructor & Destructor Documentation

◆ ValidatorRequiredUnlessStash()

ValidatorRequiredUnlessStash::ValidatorRequiredUnlessStash ( const QString field,
const QString stashKey,
const QVariant stashValues,
const ValidatorMessages messages = ValidatorMessages() 
)

Constructs a new ValidatorRequiredUnlessStash object witht the given parameters.

Parameters
fieldName of the input field to validate.
stashKeyName of the stash key to compare against.
stashValuesCan be a QString pointing to a stash key containing a QStringList or a QVariantList, directly a QStringList or directly a QVariantList. The list content must match the content of the stashKey to require the field. No entry from the list must match the content of the stashKey to require the field.
messagesCustom error messages if validation fails.

Definition at line 10 of file validatorrequiredunlessstash.cpp.

◆ ~ValidatorRequiredUnlessStash()

ValidatorRequiredUnlessStash::~ValidatorRequiredUnlessStash ( )
overridedefault

Destroys the ValidatorRequiredUnlessStash object.
