Detailed Description

Checks if the regex matches the content of the 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.

Constructor & Destructor Documentation

ValidatorRegularExpression::ValidatorRegularExpression	(	const QString &	field,
		const QRegularExpression &	regex,
		const ValidatorMessages &	messages = `ValidatorMessages()`,
		const QString &	defValKey = `QString()`
	)

Constructs a new ValidatorRegularExpression object.

Parameters

field	Name of the input field to validate.
regex	The regular expression to check against.
messages	Custom error message if validation fails.
defValKey	Stash key containing a default value if input field is empty. This value will NOT be validated.
