Detailed Description

This validator has the mandatory extra parameters type, min and max. type specifies the type to validate against, it can be either a QMetaType::Type for a number value (Int, UInt, Float, etc.) or QString, that are used as base types. You can compare against any integer, floating point or string type. If you validate a string, it’s length will be checked if it is between min and max values.

If you set a string to the min and/or max values, this will neither be interpreted as a number nor as string length, but will be used to get the comparison number value from the stash.

Note: Conversion of numeric input values is performed in the 'C' locale.; 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.

Example: Validator v({new ValidatorBetween(QStringLiteral("username"), QMetaType::QString, 3, 255))});

Constructor & Destructor Documentation

◆ ValidatorBetween()

ValidatorBetween::ValidatorBetween	(	const QString &	field,
		QMetaType::Type	type,
		const QVariant &	min,
		const QVariant &	max,
		const ValidatorMessages &	messages = `ValidatorMessages()`,
		const QString &	defValKey = `QString()`
	)

Constructs a new ValidatorBetween object with the given parameters.

Parameters

field	Name of the input field to validate.
type	The type to compare. Can be either a QMetaType::Type for a number value or QMetaType::QString.
min	Minimum value. Will be converted into comparable value. If it is a QString, it will try to get the comparison value from another params field or the stash.
max	Maximum value. Will be converted into comparable value. If it is a QString, it will try to get the comparison value from another params field or the stash.
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.
