Public Member Functions | |
Graphic2d_Circle (const Handle< Graphic2d_GraphicObject > &aGraphicObject, const Quantity_Length X, const Quantity_Length Y, const Quantity_Length Radius) | |
Creates a complete circle. The center is <X>, <Y>. The radius is <Radius>. Warning: Raises CircleDefinitionError if the radius is null. | |
Graphic2d_Circle (const Handle< Graphic2d_GraphicObject > &aGraphicObject, const Quantity_Length X, const Quantity_Length Y, const Quantity_Length Radius, const Quantity_PlaneAngle Alpha, const Quantity_PlaneAngle Beta) | |
Creates an arc. The center is <X>, <Y>. The radius is <Radius>. Angles are measured counterclockwise with 0 radian at 3 o'clock. Warning: Raises CircleDefinitionError if the radius is null. | |
void | Center (Quantity_Length &X, Quantity_Length &Y) const |
returns the coordinates of center of the circle | |
Quantity_Length | Radius () const |
returns the radius of this circle | |
Quantity_PlaneAngle | FirstAngle () const |
returns the first angle of the arc | |
Quantity_PlaneAngle | SecondAngle () const |
returns the second angle of the arc | |
void | SetCenter (const Quantity_Length X, const Quantity_Length Y) |
defines the coordinates of center of the circle | |
void | SetRadius (const Quantity_Length theR) |
defines the radius of this circle | |
void | SetAngles (const Quantity_PlaneAngle Alpha, const Quantity_PlaneAngle Beta) |
defines the angles of the arc | |

void | Draw (const Handle< Graphic2d_Drawer > &aDrawer) |
Draws the circle <me>. | |
virtual void | DrawElement (const Handle< Graphic2d_Drawer > &aDrawer, const Standard_Integer anIndex) |
Draws element <anIndex> of the circle <me>. | |
virtual void | DrawVertex (const Handle< Graphic2d_Drawer > &aDrawer, const Standard_Integer anIndex) |
Draws vertex <anIndex> of the circle <me>. | |
Standard_Boolean | Pick (const Standard_ShortReal X, const Standard_ShortReal Y, const Standard_ShortReal aPrecision, const Handle< Graphic2d_Drawer > &aDrawer) |
Returns Standard_True if the circle <me> is picked, Standard_False if not. |
