		int &	pos
	)		const `[virtual]`

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:
