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.

---Purpose: Viewer Selector for a view from V3d
-- Accepts Only Sensitive Entities inheriting Select3D entities...
class ViewerSelector2d;
---Purpose: Viewer Selector for a view from V2d
-- Accepts Only Sensitive Entities inheriting Select2D entities...
class BRepSelectionTool;
---Purpose: gives standard selections for Shapes
class BRepOwner;
---Purpose: Owner classes for BRep objects
-- used by BRepSelectionTool to know which entities
-- own the sensitive primitives created.
-- the hilight-unhilight methods are empty and
-- must be redefined by each User...
---Category: Some classes...
class BRepHilighter;
---Purpose: manages hilight of picked shapes in a ViewerSelector.
-- to be called after each pick of the selection...
