## Detailed Description

The QNodeCreatedChangeBase class is the base class for all QSceneChange events that have the changeType() NodeCreated. You should not need to instantiate this class. Usually you should be using one of its subclasses such as QNodeCreatedChange.

You can subclass this to create your own node update types for communication between your QNode and QBackendNode subclasses when writing your own aspects.
