Class Description


  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

  Example
{
   gROOT->Reset();
   TCanvas c1("c1","c1",400,400);
   TCrown cr1(.5,.5,.3,.4);
   cr1->SetLineStyle(2);
   cr1->SetLineWidth(4);
   cr1.Draw();
   TCrown cr2(.5,.5,.2,.3,45,315);
   cr2.SetFillColor(38);
   cr2.SetFillStyle(3010);
   cr2.Draw();
   TCrown cr3(.5,.5,.2,.3,-45,45);
   cr3.SetFillColor(50);
   cr3.SetFillStyle(3025);
   cr3.Draw();
   TCrown cr4(.5,.5,.0,.2);
   cr4.SetFillColor(4);
   cr4.SetFillStyle(3008);
   cr4.Draw();
}
/* */
TCrown()
 Crown default constructor.
TCrown(Double_t x1, Double_t y1,Double_t radin, Double_t radout,Double_t phimin,Double_t phimax)
 Crown normal constructor.

  x1,y1  : coordinates of centre of crown
  radin  : inner crown radius
  radout : outer crown radius
  phimin : min and max angle in degrees (default is 0-->360)
  phimax :

  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)
 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,Double_t phimax,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 OK
void Paint(Option_t *)
 Paint this crown with its current attributes
void SavePrimitive(ostream &out, Option_t * /*= ""*/)
 Save primitive as a C++ statement(s) on output stream out
