QNode::QNode(QNode * parent = 0)

Creates a new Qt3D::QNode instance with parent parent.

Note: The backend aspects will be notified that a Qt3D::QNode instance is part of the scene only if it has a parent; unless this is the root node of the Qt3D scene.

See also setParent(Qt3D::QNode *).

[virtual] QNode::~QNode()

bool QNode::blockNotifications(bool block)

If block is true, property change notifications sent by this object to aspects are blocked. If block is false, no such blocking will occur.

The return value is the previous value of notificationsBlocked().

Note that the other notification types will be sent even if the notifications for this object have been blocked.

See also notificationsBlocked().

QNodeList QNode::childrenNodes() const

Returns a list filled with the Qt3D::QNode children of the current Qt3D::QNode instance.

[protected] void QNode::cleanup()

This methods can only be called once and takes care of notyfing the backend aspects that the current Qt3D::QNode instance is about to be destroyed.

Note: It must be called by the destructor of every class subclassing Qt3D::QNode that is clonable (using the QT3D_CLONEABLE macro).

[static protected] QNode * QNode::clone(QNode * node)

Returns a clone of node. All the children of node are cloned as well.

Note: This is the only way to create two nodes with the same id.

[virtual protected] void QNode::copy(const QNode * ref)

Copies all the attributes from ref to the current Qt3D::QNode instance.

Note: When subclassing Qt3D::QNode you should reimplement this method and always call the copy method on the base class. This will ensure that when cloned, the Qt3D::QNode is properly initialized.

const QNodeId QNode::id() const

Returns the id that uniquely identifies the Qt3D::QNode instance.

bool QNode::notificationsBlocked() const

Returns true if aspect notifications are blocked; otherwise returns false. Notifications are not blocked by default.

See also blockNotifications().

QNode * QNode::parentNode() const

Returns the immediate Qt3D::QNode parent, null if the node has no parent.

Note: Getter function for property parent.

[virtual protected] void QNode::sceneChangeEvent(const QSceneChangePtr & change)

Called when one or more backend aspects sends a notification change to the current Qt3D::QNode instance.

Note: This method should be reimplemented in your subclasses to properly handle the change.

[virtual] void QNode::setParent(QNode * parent)

Sets the parent node of the current Qt3D::QNode instance to parent. Setting the parent will notify the backend aspects about current Qt3D::QNode instance's parent change.

Note: if parent happens to be null, this will actually notify that the current Qt3D::QNode instance was removed from the scene.

Note: Setter function for property parent.
