Detailed Description

Checks if the size of the value in the input field is the same as the given size.

This works for floating point, integer and QString types, where for numeric types it will check the value itself while for QString it will check the string length. Use size to define the comparison value and type to set the type to check against. size will internally converted into a comparative value (qlonglong for QMetaType::Int, qulonglong for QMetaType::UInt and int for QMetaType::QString. Allowed types for the type specifier are all numeric types and QMetaType::QString. Any other type will result in a validation data error.

If you set a string to the size value, 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.

Constructor & Destructor Documentation

◆ ValidatorSize()

ValidatorSize::ValidatorSize	(	const QString &	field,
		QMetaType::Type	type,
		const QVariant &	size,
		const ValidatorMessages &	messages = `ValidatorMessages()`,
		const QString &	defValKey = `QString()`
	)

Parameters

field	Name of the input field to validate.
type	The type to compare.
size	The size to compare. Will be converted into comparable value. If it is a QString, it will try to get the comparison value from 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.

Parameters

c	The current context, used for translations.
errorData	Will contain either 1 if comparison value is invalid or 0 if the type is not supported.
