class SensitivePoint from Select2D inherits SensitiveEntity from Select2D
---Purpose: A framework to define sensitive 2D points.

Integer from Standard,
Pnt2d from gp,
EntityOwner from SelectBasics,
ListOfBox2d from SelectBasics
is
Create (OwnerId : EntityOwner from SelectBasics;
Location : Pnt2d from gp;
InitSensitivity : Real = 0)
returns mutable SensitivePoint from Select2D;
---Purpose: Constructs the sensitive point object defined by the
-- owner OwnerId, the point Location and the sensitivity InitSensitivity.
-- InitSensitivity allows choice of dimensions in the
-- selectable box around the sensitive point. It is
-- initialized with a null value, and is given a working one by Set.
Set(me:mutable; aSensitivity:Real) is static;
---Purpose: Sets the sensitivity aSensitivity for sensitive
-- primitives to find owners of points.
Areas (me:mutable ; aresul : in out ListOfBox2d from SelectBasics) is static;
---Level: Public
---Purpose: Returns the 2Dbox around the point (this box) has to be enlarged (sensitivity = 0)
Location(me) returns Pnt2d from gp;
---Level: Public
---C++: inline
---C++: return const&
---Purpose: returns the original point.
