Detailed Description

The QtDoublePropertyManager provides and manages double properties.

A double property has a current value, and a range specifying the valid values. The range is defined by a minimum and a maximum value.

The property's value and range can be retrieved using the value(), minimum() and maximum() functions, and can be set using the setValue(), setMinimum() and setMaximum() slots. Alternatively, the range can be defined in one go using the setRange() slot.

In addition, QtDoublePropertyManager provides the valueChanged() signal which is emitted whenever a property created by this manager changes, and the rangeChanged() signal which is emitted whenever such a property changes its range of valid values.

◆ decimalsChanged

void QtDoublePropertyManager::decimalsChanged	(	QtProperty *	property,
		int	prec )

signal

This signal is emitted whenever a property created by this manager changes its precision of value, passing a pointer to the property and the new prec value

See also: setDecimals()

References QtAbstractPropertyManager::QtProperty.

Referenced by setDecimals().

◆ initializeProperty()

void QtDoublePropertyManager::initializeProperty ( QtProperty * property )

◆ isReadOnly()

bool QtDoublePropertyManager::isReadOnly ( const QtProperty * property ) const

When property is read-only it's value can be selected and copied from editor but not modified.

See also: QtDoublePropertyManager::setReadOnly

References getData(), QtAbstractPropertyManager::QtProperty, and QtDoublePropertyManagerPrivate::Data::readOnly.

◆ maximum()

double QtDoublePropertyManager::maximum ( const QtProperty * property ) const

Returns the given property's maximum value.

See also: minimum(), setRange()

References getMaximum(), and QtAbstractPropertyManager::QtProperty.

Referenced by QtDoubleSpinBoxFactory::createEditor().

◆ minimum()

double QtDoublePropertyManager::minimum ( const QtProperty * property ) const

Returns the given property's minimum value.

See also: maximum(), setRange()

References getMinimum(), and QtAbstractPropertyManager::QtProperty.

Referenced by QtDoubleSpinBoxFactory::createEditor().

◆ rangeChanged

void QtDoublePropertyManager::rangeChanged	(	QtProperty *	property,
		double	minimum,
		double	maximum )

signal

This signal is emitted whenever a property created by this manager changes its range of valid values, passing a pointer to the property and the new minimum and maximum values

See also: setRange()

References QtAbstractPropertyManager::QtProperty.

Referenced by setMaximum(), setMinimum(), and setRange().

◆ readOnlyChanged

void QtDoublePropertyManager::readOnlyChanged	(	QtProperty *	property,
		bool	readOnly )

signal

References QtDoublePropertyManager(), and QtAbstractPropertyManager::QtProperty.

Referenced by setReadOnly().

◆ setDecimals

void QtDoublePropertyManager::setDecimals	(	QtProperty *	property,
		int	prec )

slot

Sets the precision of the given property to prec.

The valid decimal range is 0-13. The default is 2.

See also: decimals()

References QtDoublePropertyManagerPrivate::Data::decimals, decimalsChanged(), and QtAbstractPropertyManager::QtProperty.

◆ setMaximum

void QtDoublePropertyManager::setMaximum	(	QtProperty *	property,
		double	maxVal )

slot

Sets the maximum value for the given property to maxVal.

When setting the maximum value, the minimum and current values are adjusted if necessary (ensuring that the range remains valid and that the current value is within in the range).

See also: maximum(), setRange(), rangeChanged()

References QtAbstractPropertyManager::propertyChanged(), QtAbstractPropertyManager::QtProperty, rangeChanged(), setMaximumValue(), and valueChanged().

◆ setMinimum

void QtDoublePropertyManager::setMinimum	(	QtProperty *	property,
		double	minVal )

slot

Sets the minimum value for the given property to minVal.

When setting the minimum value, the maximum and current values are adjusted if necessary (ensuring that the range remains valid and that the current value is within in the range).

See also: minimum(), setRange(), rangeChanged()

References QtAbstractPropertyManager::propertyChanged(), QtAbstractPropertyManager::QtProperty, rangeChanged(), setMinimumValue(), and valueChanged().

◆ setRange

void QtDoublePropertyManager::setRange	(	QtProperty *	property,
		double	minimum,
		double	maximum )

slot

Sets the range of valid values.

This is a convenience function defining the range of valid values in one go; setting the minimum and maximum values for the given property with a single function call.

When setting a new range, the current value is adjusted if necessary (ensuring that the value remains within range).

◆ setReadOnly

void QtDoublePropertyManager::setReadOnly	(	QtProperty *	property,

◆ setSingleStep

void QtDoublePropertyManager::setSingleStep	(	QtProperty *	property,
		double	step )

slot

Sets the step value for the given property to step.

The step is typically used to increment or decrement a property value while pressing an arrow key.

See also: singleStep()

References QtAbstractPropertyManager::QtProperty, QtDoublePropertyManagerPrivate::Data::singleStep, and singleStepChanged().

◆ setValue

void QtDoublePropertyManager::setValue	(	QtProperty *	property,
		double	value )

slot

Sets the value of the given property to value.

If the specified value is not valid according to the given property's range, the value is adjusted to the nearest valid value within the range.

References QtAbstractPropertyManager::propertyChanged(), QtAbstractPropertyManager::QtProperty, setValueInRange(), and valueChanged().

Referenced by main(), and QtDoubleSpinBoxFactoryPrivate::slotSetValue().

◆ singleStep()

double QtDoublePropertyManager::singleStep ( const QtProperty * property ) const

Referenced by QtDoubleSpinBoxFactory::createEditor().

◆ singleStepChanged

void QtDoublePropertyManager::singleStepChanged	(	QtProperty *	property,
		double	step )

signal

This signal is emitted whenever a property created by this manager changes its single step property, passing a pointer to the property and the new step value
