Reimplemented from QValidator.
Convert specified string to the upper/lower case if the format flags contains specificator 'u'/'l' correspondingly. If valid string length is specified, then check given string length. If filter is specified, then perform also validation with filter by QRegExpValidator.
Returns QValidator::Invalid if input is invalid according to this validator's rules, QValidator::Intermediate if it is likely that a little more editing will make the input acceptable and QValidator::Acceptable if the input is valid.
- Parameters
-
| input | string being validated |
| pos | cursor position |
- Returns
- validation state (
QValidator::State)
