Member Function Documentation

length()

int QDS_StringValidator::length

(

)

const

Get maximum valid string length.

If maximum length is not specified, -1 is returned.

Returns

maximum string length

References myLen.

setLength()

void QDS_StringValidator::setLength

(

const int

l

)

Set maximum valid string length.

If l <= 0 is not specified, maximum valid length is reset (any string length is valid).

Parameters

l	maximum strin length

References myLen.

validate()

QValidator::State QDS_StringValidator::validate ( QString &  input, int &  pos  ) const

virtual

Validate the entered string input.

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)
