base class for items that are part of a vtkContextScene. More...
#include <vtkAbstractContextItem.h>
base class for items that are part of a vtkContextScene.
This class is the common base for all context scene items. You should generally derive from vtkContextItem, rather than this class, as it provides most of the commonly used API.
