class TCrown: public TEllipse

TCrown : to draw crown

A crown is specified with the position of its centre, its inner/outer radius a minimum and maximum angle. The attributes of the outline line are given via TAttLine. The attributes of the fill area are given via TAttFill.

Function documentation


 TCrown()


   Crown default constructor.
   

 





 TCrown(Double_t x1, Double_t y1, Double_t radin, Double_t radout, Double_t phimin = 0, Double_t phimax = 360)


   Crown normal constructor.
   
    
   
  •  x1,y1  : coordinates of centre of crown
   
  •  radin  : inner crown radius
   
  •  radout : outer crown radius
   
  •  phimin : min angle in degrees (default is 0)
   
  •  phimax : max angle in degrees (default is 360)
   

   When a crown sector only is drawn, the lines connecting the center
   of the crown to the edges are drawn by default. One can specify
   the drawing option "only" to not draw these lines.
   

 





 TCrown(const TCrown& crown)


   Crown copy constructor.
   

 





 ~TCrown()


   Crown default destructor.
   

 





void Copy(TObject& crown) const


   Copy this crown to crown.
   

 





Int_t DistancetoPrimitive(Int_t px, Int_t py)


   Compute distance from point px,py to a crown.
   

   If crown is filled, return OK if we are inside
   otherwise, crown is found if near the crown edges.
   

 





void DrawCrown(Double_t x1, Double_t y1, Double_t radin, Double_t radout, Double_t phimin = 0, Double_t phimax = 360, Option_t* option = "")


   Draw this crown with new coordinates.
   

 





void ExecuteEvent(Int_t event, Int_t px, Int_t py)


   Execute action corresponding to one event
   

   For the time being TEllipse::ExecuteEvent is used.
   

 





void Paint(Option_t* option = "")


   Paint this crown with its current attributes.
   

 





void SavePrimitive(ostream& out, Option_t* option = "")


   Save primitive as a C++ statement(s) on output stream out.
