Detailed Description

The QtPointFPropertyManager provides and manages QPointF properties.

A point property has nested x and y subproperties. The top-level property's value can be retrieved using the value() function, and set using the setValue() slot.

The subproperties are created by a QtDoublePropertyManager object. This manager can be retrieved using the subDoublePropertyManager() function. In order to provide editing widgets for the subproperties in a property browser widget, this manager must be associated with an editor factory.

In addition, QtPointFPropertyManager provides the valueChanged() signal which is emitted whenever a property created by this manager changes.

Constructor & Destructor Documentation

◆ QtPointFPropertyManager()

QtPointFPropertyManager::QtPointFPropertyManager ( QObject * parent = nullptr )

Creates a manager with the given parent.

References d_ptr, QtPointFPropertyManagerPrivate::m_doublePropertyManager, QtAbstractPropertyManager::propertyDestroyed(), QtPointFPropertyManagerPrivate::q_ptr, and valueChanged().

◆ ~QtPointFPropertyManager()

QtPointFPropertyManager::~QtPointFPropertyManager ( )

override

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

References QtAbstractPropertyManager::clear(), and d_ptr.

Member Function Documentation

◆ decimals()

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

Returns the given property's precision, in decimals.

See also: setDecimals()

References d_ptr, QtPointFPropertyManagerPrivate::Data::decimals, and QtPointFPropertyManagerPrivate::m_values.

Referenced by initializeProperty().

◆ decimalsChanged

void QtPointFPropertyManager::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()

Referenced by setDecimals().

◆ initializeProperty()

void QtPointFPropertyManager::initializeProperty ( QtProperty * property )

overrideprotectedvirtual

Implements QtAbstractPropertyManager.

References QtAbstractPropertyManager::addProperty(), QtProperty::addSubProperty(), d_ptr, decimals(), QtPointFPropertyManagerPrivate::m_doublePropertyManager, QtPointFPropertyManagerPrivate::m_propertyToX, QtPointFPropertyManagerPrivate::m_propertyToY, QtPointFPropertyManagerPrivate::m_values, QtPointFPropertyManagerPrivate::m_xToProperty, QtPointFPropertyManagerPrivate::m_yToProperty, QtDoublePropertyManager::setDecimals(), QtProperty::setPropertyName(), and QtDoublePropertyManager::setValue().

◆ Q_PRIVATE_SLOT()

	)

private

◆ setDecimals

void QtPointFPropertyManager::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.

References d_ptr, QtPointFPropertyManagerPrivate::Data::decimals, decimalsChanged(), QtPointFPropertyManagerPrivate::m_doublePropertyManager, QtPointFPropertyManagerPrivate::m_propertyToX, QtPointFPropertyManagerPrivate::m_propertyToY, QtPointFPropertyManagerPrivate::m_values, and QtDoublePropertyManager::setDecimals().

◆ setValue

void QtPointFPropertyManager::setValue	(	QtProperty *	property,
		const QPointF &	value
	)

slot

Sets the value of the given property to value. Nested properties are updated automatically.

See also: value(), valueChanged()

References d_ptr, QtPointFPropertyManagerPrivate::m_doublePropertyManager, QtPointFPropertyManagerPrivate::m_propertyToX, QtPointFPropertyManagerPrivate::m_propertyToY, QtPointFPropertyManagerPrivate::m_values, QtAbstractPropertyManager::propertyChanged(), QtDoublePropertyManager::setValue(), and valueChanged().

◆ subDoublePropertyManager()

QtDoublePropertyManager * QtPointFPropertyManager::subDoublePropertyManager ( ) const

Returns the manager that creates the nested x and y subproperties.

In order to provide editing widgets for the subproperties in a property browser widget, this manager must be associated with an editor factory.

See also: QtAbstractPropertyBrowser::setFactoryForManager()

References d_ptr, and QtPointFPropertyManagerPrivate::m_doublePropertyManager.

◆ uninitializeProperty()

void QtPointFPropertyManager::uninitializeProperty ( QtProperty * property )

overrideprotectedvirtual

Reimplemented from QtAbstractPropertyManager.

References d_ptr, QtPointFPropertyManagerPrivate::m_propertyToX, QtPointFPropertyManagerPrivate::m_propertyToY, QtPointFPropertyManagerPrivate::m_values, QtPointFPropertyManagerPrivate::m_xToProperty, and QtPointFPropertyManagerPrivate::m_yToProperty.

◆ value()

QPointF QtPointFPropertyManager::value ( const QtProperty * property ) const

Returns the given property's value.

If the given property is not managed by this manager, this function returns a point with coordinates (0, 0).

See also: setValue()

References d_ptr, and QtPointFPropertyManagerPrivate::m_values.

◆ valueChanged

void QtPointFPropertyManager::valueChanged	(	QtProperty *	property,
		const QPointF &	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.
