Data Members

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();
}

 Crown default constructor.

 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.

 Crown copy constructor.

 Crown default destructor.

 Copy this crown to crown.

 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

 Draw this crown with new coordinates

 Execute action corresponding to one event

  For the time being TEllipse::ExecuteEvent is OK

 Paint this crown with its current attributes

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