The QSGRootNode is the toplevel root of any scene graph.
The root node is used to attach a scene graph to a renderer.
| QSGRootNode::QSGRootNode | ( | ) |
Creates a new root node.
Definition at line 1212 of file qsgnode.cpp.

override |
Deletes the root node.
When a root node is deleted it removes itself from all of renderers that are referencing it.
