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.

Constructor & Destructor Documentation

QtDoublePropertyManager::QtDoublePropertyManager ( QObject * parent = 0 )

Creates a manager with the given parent.

QtDoublePropertyManager::~QtDoublePropertyManager ( )

Destroys this manager, and all the properties it has created.

Member Function Documentation

int QtDoublePropertyManager::decimals ( const QtProperty * property ) const

Returns the given property's precision, in decimals.

See also:: setDecimals()

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()

void QtDoublePropertyManager::initializeProperty ( QtProperty * property ) [protected, virtual]

Implements QtAbstractPropertyManager.

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

Returns the given property's maximum value.

See also:: minimum(), setRange()

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

Returns the given property's minimum value.

See also:: maximum(), setRange()

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()

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()

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()

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()

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).

See also:: setMinimum(), setMaximum(), rangeChanged()

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()

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.

See also:: value(), setRange(), valueChanged()

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

Returns the given property's step value.

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

See also:: setSingleStep()

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

See also:: setSingleStep()

void QtDoublePropertyManager::uninitializeProperty ( QtProperty * property ) [protected, virtual]

Reimplemented from QtAbstractPropertyManager.

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

Returns the given property's value.

If the given property is not managed by this manager, this function returns 0.

See also:: setValue()

void QtDoublePropertyManager::valueChanged	(	QtProperty *	property,
		double	value
	)		`[signal]`

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

See also:: setValue()

QString QtDoublePropertyManager::valueText ( const QtProperty * property ) const [protected, virtual]

Reimplemented from QtAbstractPropertyManager.
