DESCRIPTION

       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.

       See also QIntValidator.


MEMBER FUNCTION DOCUMENTATION


QDoubleValidator::QDoubleValidator ( QWidget * parent, const char

       * name = 0 )
       Constructs a validator object which accepts all doubles.


QDoubleValidator::QDoubleValidator ( double bottom, double top,

       int decimals, QWidget * parent, const char * name = 0 )
       Constructs a validator object which accepts all doubles
       from bottom up to and including top with at most decimals
       digits after the decimal point.

       Destroys the validator, freeing any storage and other
       resources used.


double QDoubleValidator::bottom () const

       Returns the lowest valid number according to this
       validator.

       See also top(), decimals() and setRange().


int QDoubleValidator::decimals () const

       Returns the largest number of digits a valid number can
       have after its decimal point.

       See also bottom(), top() and setRange().


void QDoubleValidator::setBottom ( double bottom )

       Sets the validator to accept no numbers smaller than
       bottom.

       See also setRange().


void QDoubleValidator::setDecimals ( int decimals )

       Sets the maximum number of digits after the decimal point.


void QDoubleValidator::setRange ( double bottom, double top, int

       decimals = 0 ) [virtual]
       Sets the validator to accept numbers from bottom up to and
       including top with at most decimals digits after the
       decimal point.


void QDoubleValidator::setTop ( double top )

       Sets the validator to accept no numbers bigger than top.

       See also setRange().


double QDoubleValidator::top () const

       Returns the highest valid number according to this
       validator.

       See also bottom(), decimals() and setRange().


QValidator::State QDoubleValidator::validate( QString & input,

       int & ) const
       Returns Acceptable if input contains a number in the legal
       range and format, Intermediate if it contains another
       number, a number with too many digits after the decimal
       point or is empty, and Invalid if input is not a number.
