成员函数
QBackendNode::QBackendNode(Mode mode = ReadOnly)
Default constructs an instance of QBackendNode.
[virtual] QBackendNode::~QBackendNode()
Destroys the instance of QBackendNode. The destructor is virtual.
bool QBackendNode::isEnabled() const
Returns true if the backend node is enabled.
Mode QBackendNode::mode() const
Returns the mode of the backend mode.
[protected] void QBackendNode::notifyObservers(const QSceneChangePtr &e)
Notifies observers of scene change e.
QNodeId QBackendNode::peerId() const
Returns the peer id of the backend node.
[virtual protected] void QBackendNode::sceneChangeEvent(const QSceneChangePtr &e)
TODO e
void QBackendNode::setEnabled(bool enabled)
Enables or disables the backend node by enabled.
