Detailed Description
The base class for changes that can be sent and received by Qt3D's change notification system.
Member Type Documentation
enum QSceneChange::DeliveryFlag
flags QSceneChange::DeliveryFlags
The types of change that can be sent and received by Qt3D's change notification system.
| Constant | Value |
|---|---|
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.
Member Function Documentation
[protected] QSceneChange::QSceneChange(Qt3DCore::ChangeFlag type, Qt3DCore::QNodeId subjectId)
Constructs a new QSceneChange with type and subjectId.
[virtual] QSceneChange::~QSceneChange()
Destroys the instance of QSceneChange. The destructor is virtual.
Qt3DCore::QSceneChange::DeliveryFlags QSceneChange::deliveryFlags() const
Returns the set delivery flags.
See also setDeliveryFlags().
void QSceneChange::setDeliveryFlags(Qt3DCore::QSceneChange::DeliveryFlags flags)
Sets the delivery flags of the change to flags.
See also deliveryFlags().
Qt3DCore::QNodeId QSceneChange::subjectId() const
Returns scene change subject id.
Qt3DCore::ChangeFlag QSceneChange::type() const
Returns the scene change type.

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::CommandRequested | 1 << 7 | A QNodeCommand has been sent between a node and its backend. |
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::CallbackTriggered | 1 << 8 | A QNode triggered a callback. |
Qt3DCore::AllChanges | 0xFFFFFFFF | Allows an observer to monitor for any of the above changes. |
The ChangeFlags type is a typedef for QFlags<ChangeFlag>. It stores an OR combination of ChangeFlag values.
