Detailed Description

A base class that is used for displaying SkyComponents on SkyMapLite.

This is an interface for implementing SkyItems that represent SkyComponent derived objects on the SkyMapLite. It is derived from QSGOpacityNode to make it possible to hide the whole node tree by simply setting opacity to 0.
