	Graphic2d_Segment (const Handle< Graphic2d_GraphicObject > &aGraphicObject, const Quantity_Length X1, const Quantity_Length Y1, const Quantity_Length X2, const Quantity_Length Y2)
	Creates a segment in the graphic object <aGraphicObject>. The first point is <X1>, <Y1>. The second point is <X2>, <Y2>. Warning: Raises SegmentDefinitionError if the first point and the second point are identical.
void	FirstPoint (Quantity_Length &X, Quantity_Length &Y) const
	returns the coordinates of the first point of the segment
void	SecondPoint (Quantity_Length &X, Quantity_Length &Y) const
	returns the coordinates of the second point of the segment
virtual void	Save (Aspect_FStream &aFStream) const
Static Public Member Functions
static void	Retrieve (Aspect_IFStream &anIFStream, const Handle< Graphic2d_GraphicObject > &aGraphicObject)
Protected Member Functions
void	Draw (const Handle< Graphic2d_Drawer > &aDrawer)
	Draws the segment <me>.
virtual void	DrawElement (const Handle< Graphic2d_Drawer > &aDrawer, const Standard_Integer anIndex)
	Draws edge <anIndex> of the segment <me>.
virtual void	DrawVertex (const Handle< Graphic2d_Drawer > &aDrawer, const Standard_Integer anIndex)
	Draws vertex <anIndex> of the segment <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 segment <me> is picked, Standard_False if not.
