Inherits QValidator.
The QDoubleValidator class provides range checking of floating-point numbers.
QDoubleValidator provides an upper bound, a lower bound, and a limit on the number of digits after the decimal point. It does not provide a fixup function.
You can set the acceptable range in one call with setRange, or with setBottom and setTop. Set the number of decimal places with setDecimals. The validate function returns the validation state.
QDoubleValidator uses its locale to interpret the number. For example, in the German locale, "1,234" will be accepted as the fractional number 1.234. In Arabic locales, QDoubleValidator will accept Arabic digits.
In addition, QDoubleValidator is always guaranteed to accept a number formatted according to the "C" locale. QDoubleValidator will not accept numbers with thousand-seperators.
