24 class Circle from AIS inherits InteractiveObject from AIS
26 ---Purpose: Constructs circle datums to be used in construction of
32 Presentation from Prs3d,
33 PresentationManager3d from PrsMgr,
34 NameOfColor from Quantity,
36 Selection from SelectMgr,
38 Transformation from Geom,
40 KindOfInteractive from AIS
44 Create(aCircle : Circle from Geom)
45 returns mutable Circle from AIS;
46 ---Purpose: Initializes this algorithm for constructing AIS circle
47 -- datums initializes the circle aCircle
48 Create(aCircle : Circle from Geom;
49 aUStart : Real from Standard;
50 aUEnd : Real from Standard;
51 aSens : Boolean from Standard = Standard_True)
52 returns mutable Circle from AIS;
53 ---Purpose: Initializes this algorithm for constructing AIS circle datums.
54 -- Initializes the circle aCircle, the arc
55 -- starting point UStart, the arc ending point UEnd,
56 -- and the direction aSens.
59 aPresentationManager: PresentationManager3d from PrsMgr;
60 aPresentation : mutable Presentation from Prs3d;

67 is redefined static private;
70 aProjector : Projector from Prs3d;
71 aTrsf : Transformation from Geom;
72 aPresentation : mutable Presentation from Prs3d)
74 ---Purpose: computes the presentation according to a point of view
75 -- given by <aProjector>.
76 -- To be Used when the associated degenerated Presentations
77 -- have been transformed by <aTrsf> which is not a Pure
78 -- Translation. The HLR Prs can't be deducted automatically
79 -- WARNING :<aTrsf> must be applied
80 -- to the object to display before computation !!!

89 -- Methods from InteractiveObject
92 Signature(me) returns Integer from Standard is redefined;
94 ---Purpose: Returns index 6 by default.
96 Type(me) returns KindOfInteractive from AIS is redefined;
98 ---Purpose: Indicates that the type of Interactive Object is a datum.
100 Circle(me) returns any Circle from Geom;
102 ---C++: return const &
103 ---Purpose: Returns the circle component defined in SetCircle.
105 Parameters(me; u1,u2 : in out Real from Standard);
108 -- Constructs instances of the starting point and the end
109 -- point parameters, u1 and u2.
111 SetCircle(me:mutable;aCircle : Circle from Geom);
113 ---Purpose: Allows you to provide settings for the circle datum aCircle.
115 SetFirstParam(me:mutable;u:Real);
117 ---Purpose: Allows you to set the parameter u for the starting point of an arc.
119 SetLastParam(me:mutable;u:Real);
121 ---Purpose: Allows you to provide the parameter u for the end point of an arc.
123 SetColor(me :mutable; aColor : NameOfColor from Quantity)
125 --- Purpose: Assigns the color aColor to the solid line boundary of the circle datum.
126 SetColor(me :mutable; aColor : Color from Quantity)
129 SetWidth(me:mutable; aValue:Real from Standard)
131 ---Purpose: Assigns the width aValue to the solid line boundary of the circle datum.
132 UnsetColor(me:mutable)
134 ---Purpose: Removes color from the solid line boundary of the circle datum.
135 UnsetWidth(me:mutable)
137 ---Purpose: Removes width settings from the solid line boundary of the circle datum.
