Detailed Description

Validates if the field contains a value from the values list.

Note
Unless validation is started with NoTrimming, whitespaces will be removed from the beginning and the end of the input value before validation. If the field's value is empty or if the field is missing in the input data, the validation will succeed without performing the validation itself. Use one of the required validators to require the field to be present and not empty.

Validator for general usage of validators.

ValidatorIn::ValidatorIn ( const QString &  field,
const QVariant &  values,
Qt::CaseSensitivity  cs = Qt::CaseSensitive,
const ValidatorMessages messages = ValidatorMessages(),
const QString &  defValKey = QString() 
)
Parameters
fieldName of the input field to validate.
valuesList of values to compare against. Can be either a QStringList containing the allowed values or a QString specifing a stash key containing a QStringList with allowed values.
csDefines if the comparison should be performed case sensitive or insensitive.
messagesCustom error message if validation fails.
defValKeyStash key containing a default value if input field is empty. This value will NOT be validated.
