Detailed Description

This will check if the value in the one input field is different from the value in the other input field.

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.
Return type
On success, ValidatorReturnType::value will contain a QString.

Validator for general usage of validators.

Parameters
fieldName of the input field to validate.
otherName of the other field to compare against.
otherLabelTranslatable label of the other input field, used for generic error messages.
messagesCustom error messages if validation fails.
