Detailed 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. +

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. +

Member Function Documentation

QDoubleValidator::QDoubleValidator ( QObject * parent, const char * name = 0 ) +

+Constructs a validator object with parent parent, called name, which accepts any double. + +

QDoubleValidator::QDoubleValidator ( double bottom, double top, int decimals, QObject * parent, const char * name = 0 ) +

+Constructs a validator object with parent parent, called name. This validator will accept doubles from bottom to top +inclusive, with up to decimals digits after the decimal point. + +

QDoubleValidator::~QDoubleValidator () +

+Destroys the validator, freeing any resources used. + +

double QDoubleValidator::bottom () const +

Returns the validator's minimum acceptable value. +See the "bottom" property for details. +

int QDoubleValidator::decimals () const +

Returns the validator's maximum number of digits after the decimal point. +See the "decimals" property for details. +

void QDoubleValidator::setBottom ( double ) +

Sets the validator's minimum acceptable value. +See the "bottom" property for details. +

void QDoubleValidator::setDecimals ( int ) +

Sets the validator's maximum number of digits after the decimal point. +See the "decimals" property for details. +

void QDoubleValidator::setRange ( double minimum, double maximum, int decimals = 0 ) `[virtual]` +

+Sets the validator to accept doubles from minimum to maximum +inclusive, with at most decimals digits after the decimal +point. + +

void QDoubleValidator::setTop ( double ) +

Sets the validator's maximum acceptable value. +See the "top" property for details. +

double QDoubleValidator::top () const +

Returns the validator's maximum acceptable value. +See the "top" property for details. +

QValidator::State QDoubleValidator::validate ( QString & input, int & ) const `[virtual]` +

+Returns Acceptable if the string input contains a double +that is within the valid range and is in the correct format. +

Returns Intermediate if input contains a double that is +outside the range or is in the wrong format, e.g. with too many +digits after the decimal point or is empty. +

Returns Invalid if the input is not a double. +

Note: If the valid range consists of just positive doubles (e.g. 0.0 - 100.0) +and input is a negative double then Invalid is returned. + +

Reimplemented from QValidator. +
