package StdSelect 

	---Purpose: The StdSelect package provides the following services
    	-- -   the definition of selection modes for topological shapes
    	-- -   the definition of several concrete filtertandard
    	--   Selection2d.ap classes
    	-- -   2D and 3D viewer selectors.
    	--  Note that each new Interactive Object must have all
    	-- its selection modes defined.
    	--        Standard Classes is useful to build
	--          3D Selectable Objects, and to process
	--          3D Selections:
	--          
	--          - Implementation of View Selector for dynamic selection
	--            in Views from V3d.
	--          
	--          - Implementation of Tool class to decompose 3D BRep Objects
	--            into sensitive Primitives for every desired mode of selection
	--            (selection of vertex,edges,wires,faces,...)
	--            
	--          -  Implementation of dedicated Sensitives Entities:
	--             Text for 2D Views (linked to Specific 2D projectors.)

    enumeration TypeOfResult is TOR_SIMPLE,TOR_MULTIPLE
    end TypeOfResult;
    	---Purpose: Provides values for type of result.
    	-- These are used to specify whether the result is to
    	-- be simple or whether it may be multiple.
        
    enumeration DisplayMode is DM_Wireframe,DM_Shading,DM_HLR
    end DisplayMode;
    
--    enumeration TypeOfFace is AnyFace,Plane,Cylinder,Sphere,Torus,Revol;
    enumeration TypeOfFace is AnyFace,Plane,Cylinder,Sphere,Torus,Revol,Cone;
    	---Purpose: Provides values for different types of faces. These
    	-- values are used to filter faces in frameworks inheriting
    	-- StdSelect_FaceFilter.
    
    enumeration TypeOfEdge is AnyEdge,Line,Circle;
    	---Purpose: Provides values for different types of edges. These
    	-- values are used to filter edges in frameworks
    	-- inheriting StdSelect_EdgeFilter.
    
    enumeration SensitivityMode is SM_WINDOW, SM_VIEW;
    	---Purpose: Selection sensitivity mode. SM_WINDOW mode uses the
    	-- specified pixel tolerance to compute the sensitivity value,
    	-- SM_VIEW mode allows to define the sensitivity manually.
