The base class for changes that can be sent and received by Qt3D's change notification system

成员类型文档编制

enum QSceneChange:: DeliveryFlag
flags QSceneChange:: DeliveryFlags

The types of change that can be sent and received by Qt3D's change notification system.

常量	值
Qt3DCore::QSceneChange::BackendNodes	0x0001
Qt3DCore::QSceneChange::Nodes	0x0010
Qt3DCore::QSceneChange::DeliverToAll	BackendNodes | Nodes

The DeliveryFlags type is a typedef for QFlags <DeliveryFlag>. It stores an OR combination of DeliveryFlag values.

成员函数文档编制

[protected] QSceneChange:: QSceneChange ( ChangeFlag type , QNodeId subjectId )

构造新的 QSceneChange with type and subjectId .

[virtual] QSceneChange:: ~QSceneChange ()

Destroys the instance of QSceneChange. The destructor is virtual.

DeliveryFlags QSceneChange:: deliveryFlags () const

Returns the set delivery flags

另请参阅 setDeliveryFlags ().

void QSceneChange:: setDeliveryFlags ( DeliveryFlags flags )

Set the Delivery flags of the change to flags

另请参阅 deliveryFlags ().

QNodeId QSceneChange:: subjectId () const

Returns scene change subject id.

ChangeFlag QSceneChange:: type () const

Returns scene change type.

常量	值	描述
Qt3DCore::NodeCreated	1<<0	A new instance of a QNode subclass has been created.
Qt3DCore::NodeDeleted	1<<1	A QNode has been deleted.
Qt3DCore::PropertyUpdated	1<<2	A QNode property has been updated.
Qt3DCore::PropertyValueAdded	1<<3	A QNode has been added to the scene.
Qt3DCore::PropertyValueRemoved	1<<4	A QNode has been removed from the scene.
Qt3DCore::ComponentAdded	1<<5	A QComponent has been added to a QEntity .
Qt3DCore::ComponentRemoved	1<<6	A QComponent has been removed from a QEntity .
Qt3DCore::AllChanges	0xFFFFFFFF	Allows an observer to monitor for any of the above changes.

ChangeFlags 类型是 typedef 对于 QFlags <ChangeFlag>。它存储 ChangeFlag 值的 OR 组合。

typedef Qt3DCore:: QSceneChangePtr
