DisplayObjectContainer class - stagexl library

The base class for all objects that can serve as display object containers on the display list.

The display list manages all objects displayed. Use the DisplayObjectContainer class to arrange the display objects in the display list. Each DisplayObjectContainer object has its own child list for organizing the z-order of the objects. The z-order is the front-to-back order that determines which object is drawn in front, which is behind, and so on.
