Detailed Description

Checks if the field contains a valid URL by loading it into a QUrl and testing it’s validity.

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 QUrl.
See also
Validator for general usage of validators.

Member Enumeration Documentation

◆ Constraint

Constraints to limit the validation.

Enumerator
NoConstraint 

No constraints set.

StrictParsing 

String will be parsed in strict mode. See QUrl::ParsingMode

NoRelative 

Relative URLs are not valid.

NoLocalFile 

Local file URLs are not Vaid.

WebsiteOnly 

Combines NoRelative and NoLocalFile and sets http and https to the schemes list. (Will overwrite existing list)

Constructor & Destructor Documentation

◆ ValidatorUrl()

ValidatorUrl::ValidatorUrl ( const QString & field,
Constraints constraints = NoConstraint,
const QStringList & schemes = QStringList(),
const ValidatorMessages & messages = ValidatorMessages(),
const QString & defValKey = QString() )

Constructs a new ValidatorUrl object with the given parameters.

Parameters
fieldName of the input field to validate.
constraintsConstraints for parsing and validating the URL.
schemesList of allowed schemes for a valid URL.
messagesCustom error messages if validation fails.
defValKeyStash key containing a default value if input field is empty. This value will NOT be validated.
