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.
