Member Function Documentation
QBackendNode::QBackendNode(Qt3DCore::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.
Qt3DCore::QBackendNode::Mode QBackendNode::mode() const
Returns the mode of the backend mode.
[protected] void QBackendNode::notifyObservers(const Qt3DCore::QSceneChangePtr &e)
Notifies observers of scene change e.
Qt3DCore::QNodeId QBackendNode::peerId() const
Returns the peer id of the backend node.
[virtual protected] void QBackendNode::sceneChangeEvent(const Qt3DCore::QSceneChangePtr &e)
TODO e
[protected] QNodeCommand::CommandId QBackendNode::sendCommand(const QString &name, const QVariant &data, QNodeCommand::CommandId replyTo = QNodeCommand::CommandId())
Send the command named name with contents data, and specify replyTo as the command id to which the reply needs to be sent.
[protected] void QBackendNode::sendReply(const Qt3DCore::QNodeCommandPtr &command)
Send the reply to command.
void QBackendNode::setEnabled(bool enabled)
Enables or disables the backend node by enabled.
