QSortPolicy¶
- PyQt5.Qt3DRender.QSortPolicy
Inherits from QFrameGraphNode.
Description¶
Provides storage for the sort types to be used.
A QSortPolicy class stores the sorting type used by the FrameGraph. The sort types determine how drawable entities are sorted before drawing to determine the drawing order. When QSortPolicy is present in the FrameGraph, the sorting mechanism is determined by the SortTypes list. Multiple sort types can be used simultaneously. If QSortPolicy is not present in the FrameGraph, entities are drawn in the order they appear in the entity hierarchy.
