Detailed Description

The difference to the required validator is, that it will only be checked for non emptyness if it is available. If it is available, it is not allowed to be empty.

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

Validator for general usage of validators.
