qreal | calculatedValue (const QObject *autoArea, KDChartEnums::MeasureOrientation autoOrientation) const |
The reference area must either be derived from AbstractArea or be derived from QWidget, so e.g. | |
KDChartEnums::MeasureCalculationMode | calculationMode () const |
Measure (const Measure &) | |
Measure (qreal value, KDChartEnums::MeasureCalculationMode mode=KDChartEnums::MeasureCalculationModeAuto, KDChartEnums::MeasureOrientation orientation=KDChartEnums::MeasureOrientationAuto) | |
Measure () | |
bool | operator!= (const Measure &other) const |
Measure & | operator= (const Measure &) |
bool | operator== (const Measure &) const |
const QObject * | referenceArea () const |
The returned reference area will either be derived from AbstractArea or be derived from QWidget. | |
KDChartEnums::MeasureOrientation | referenceOrientation () const |
void | setAbsoluteValue (qreal val) |
This is a convenience method for specifying a value, with implicitely setting the calculation mode to MeasureCalculationModeAbsolute. | |
void | setCalculationMode (KDChartEnums::MeasureCalculationMode mode) |
void | setReferenceArea (const QObject *area) |
The reference area must either be derived from AbstractArea or be derived from QWidget, so e.g. | |
void | setReferenceOrientation (KDChartEnums::MeasureOrientation orientation) |
void | setRelativeMode (const QObject *area, KDChartEnums::MeasureOrientation orientation) |
The reference area must either be derived from AbstractArea or be derived from QWidget, so e.g. | |
void | setValue (qreal val) |
const QSizeF | sizeOfArea (const QObject *area) const |
qreal | value () const |
