## Public Member Functions
| KDoubleValidator (QObject *parent, const char *name=0)
| Constuct a locale-aware KDoubleValidator with default range (whatever QDoubleValidator uses for that) and parent `parent`.
| KDoubleValidator (double bottom, double top, int decimals, QObject *parent, const char *name=0)
| Constuct a locale-aware KDoubleValidator for range [`bottom`,`top`] and a precision of `decimals` decimals after the decimal point.
virtual | ~KDoubleValidator ()
| Destructs the validator.
virtual QValidator::State | validate (QString &input, int &pos) const
| Overloaded for internal reasons.
bool | acceptLocalizedNumbers () const
void | setAcceptLocalizedNumbers (bool accept)
| Sets whether to accept localized numbers (default: true).

## Detailed Description

KDoubleValidator extends QDoubleValidator to be locale-aware. A locale-aware QDoubleValidator.

That means that - subject to not being disabled - KLocale::decimalPoint(), KLocale::thousandsSeparator() and KLocale::positiveSign() and KLocale::negativeSign() are respected.
