Detailed Description
A QSGClipNode derived class used as a container for holding pointers to nodes and for clipping.
Upon construction RootNode generates all textures that are used by PointNode.
KStars Lite has the following hierarchy:
- RootNode - the parent of all nodes that also acts as a clipping node
- SkyItem derived nodes that acts like SkyComponent in regular KStars
- SkyNode derived nodes that represent SkyObjects (similar to SkyComponent::draw())
- Simple nodes like EllipseNode or PointNode that draw basic geometry and stars
A container for nodes that holds collection of textures for stars and provides clipping
- Version
- 1.0
