Class Description


 A Graphical line
TLine()
 Line default constructor.
TLine(Double_t x1, Double_t y1, Double_t x2, Double_t y2)
 Line normal constructor.
~TLine()
 Line default destructor.
TLine(const TLine &line)
 Line copy constructor.
void Copy(TObject &obj)
 Copy this line to line.
Int_t DistancetoPrimitive(Int_t px, Int_t py)
 Compute distance from point px,py to a line.
TLine * DrawLine(Double_t x1, Double_t y1, Double_t x2, Double_t y2)
 Draw this line with new coordinates.
TLine * DrawLineNDC(Double_t x1, Double_t y1, Double_t x2, Double_t y2)
 Draw this line with new coordinates in NDC.
void ExecuteEvent(Int_t event, Int_t px, Int_t py)
 Execute action corresponding to one event.
  This member function is called when a line is clicked with the locator

  If Left button clicked on one of the line end points, this point
     follows the cursor until button is released.

  if Middle button clicked, the line is moved parallel to itself
     until the button is released.
void ls(Option_t *)
 List this line with its attributes.
void Paint(Option_t *)
 Paint this line with its current attributes.
void PaintLine(Double_t x1, Double_t y1, Double_t x2, Double_t y2)
 Draw this line with new coordinates.
void PaintLineNDC(Double_t u1, Double_t v1, Double_t u2, Double_t v2)
 Draw this line with new coordinates in NDC.
void Print(Option_t *)
 Dump this line with its attributes.
void SavePrimitive(ostream &out, Option_t * /*= ""*/)
 Save primitive as a C++ statement(s) on output stream out
Bool_t IsHorizontal()
 Check whether this line is to be drawn horizontally.
Bool_t IsVertical()
 Check whether this line is to be drawn vertically.
void SetHorizontal(Bool_t set /*= kTRUE*/)
 Force the line to be drawn horizontally.
 Makes fY2 equal to fY1. The line length is kept.
 TArrow and TGaxis also get this function by inheritance.
void SetVertical(Bool_t set /*= kTRUE*/)
 Force the line to be drawn vertically.
 Makes fX2 equal to fX1. The line length is kept.
 TArrow and TGaxis also get this function by inheritance.
void Streamer(TBuffer &R__b)
 Stream an object of class TLine.
Double_t GetX1()
{return fX1;}
Double_t GetX2()
{return fX2;}
Double_t GetY1()
{return fY1;}
Double_t GetY2()
{return fY2;}
void SetX1(Double_t x1)
{fX1=x1;}
void SetX2(Double_t x2)
{fX2=x2;}
void SetY1(Double_t y1)
{fY1=y1;}
void SetY2(Double_t y2)
{fY2=y2;}
