Detailed Description

This validator checks if the input field can be parsed into a QDate, it will check the parsing ability and will convert the input data into a QDate. 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 based on standard formats in the following order: Context locale's toDate() with QLocale::ShortFormat and QLocale::LongFormat, Qt::ISODate, Qt::RFC2822Date, Qt::TextDate

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.
