KFloatValidator::KFloatValidator | ( | QWidget * | parent,
|  | const char * | name = 0
| ) |

| Constructor. Definition at line 165 of file knumvalidator.cpp. References KStdAccel::name().

KFloatValidator::KFloatValidator | ( | double | bottom,
|  | double | top,
|  | QWidget * | parent,
|  | const char * | name = 0
| ) |

| Constructor. Also sets the minimum and maximum values. Definition at line 173 of file knumvalidator.cpp. References KStdAccel::name().

KFloatValidator::KFloatValidator | ( | double | bottom,
|  | double | top,
|  | bool | localeAware,
|  | QWidget * | parent,
|  | const char * | name = 0
| ) |

| Constructor. Sets the validator to be locale aware if `localeAware` is true. Definition at line 182 of file knumvalidator.cpp. References KStdAccel::name().

| Destructs the validator. Definition at line 191 of file knumvalidator.cpp.

## Member Function Documentation

QValidator::State KFloatValidator::validate | ( | QString & | ,
|  | int & |
| ) | const`[virtual]`

| Validates the text, and return the result. Does not modify the parameters. Reimplemented from QValidator. Definition at line 207 of file knumvalidator.cpp. References KLocale::decimalSymbol(), QString::fromLatin1(), QString::length(), KGlobal::locale(), KLocale::readNumber(), QString::stripWhiteSpace(), and QString::toDouble(). Referenced by fixup().

void KFloatValidator::fixup | ( | QString & |  | ) | const`[virtual]`

| Fixes the text if possible, providing a valid string. The parameter may be modified. Reimplemented from QValidator. Definition at line 247 of file knumvalidator.cpp. References QString::setNum(), QString::toDouble(), and validate().

void KFloatValidator::setRange | ( | double | bottom,
|  | double | top
| ) | `[virtual]`

| Sets the minimum and maximum value allowed. Definition at line 269 of file knumvalidator.cpp.

double KFloatValidator::bottom | ( |  | ) | const`[virtual]`

| Returns the current minimum value allowed. Definition at line 278 of file knumvalidator.cpp.

double KFloatValidator::top | ( |  | ) | const`[virtual]`

| Returns the current maximum value allowed. Definition at line 283 of file knumvalidator.cpp.

void KFloatValidator::setAcceptLocalizedNumbers | ( | bool | b | ) |

| Sets the validator to be locale aware if `is` true. In this case, the character KLocale::decimalSymbol() from the global locale is recognized as decimal separator. Definition at line 196 of file knumvalidator.cpp.

bool KFloatValidator::acceptLocalizedNumbers | ( |  | ) | const

Returns true if the validator is locale aware.
