Detailed Description

This validator checks if the input field can be parsed into a QDateTime, it will check the parsing ability and will convert the input data into a QDateTime. If a custom inputFormat is given, the validator will at first try to parse the date according to that format. If that fails or if there is no custom inputFormat set, it will try to parse the date and time based on standard formats in the following order: Context locale's toDateTime() with QLocale::ShortFormat and QLocale::LongFormat, Qt::ISODate, Qt::RFC2822Date, Qt::TextDate

To specify a time zone that should be used for the input field - and the comparison input field if one is used, give either the IANA time zone ID name to the timeZone argument of the constructor or the name of an input field or stash key that contains the ID name. It will then be first tried to create a valid QTimeZone from the timeZone, if that fails it will first tryp to get the time zone from the input parameters and if there is no key with the name trying it with the stash. Stash or input parameter can either contain a valid IANA time zone ID or the offset from UTC in seconds.

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

ValidatorDateTime()

ValidatorDateTime::ValidatorDateTime	(	const QString &	field,
		const QString &	timeZone,
		const char *	inputFormat = nullptr,
		const ValidatorMessages &	messages = ValidatorMessages(),
		const QString &	defValKey = QString()
	)

Parameters

field	Name of the input field to validate.
timeZone	IANA time zone ID, name of a input field containing the ID or stash key containing the ID
inputFormat	Optional input format for input data parsing, can be translatable.
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.
