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.

QDoubleValidator::~QDoubleValidator ()
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.
