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 | |

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. |
