class TCurlyArc: public TCurlyLine


 This class implements curly or wavy arcs typically used to draw Feynman diagrams.
 Amplitudes and wavelengths may be specified in the constructors,
 via commands or interactively from popup menus.
 The class make use of TCurlyLine by inheritance, ExecuteEvent methods
 are highly inspired from the methods used in TPolyLine and TArc.

Function documentation

TCurlyArc(Double_t x1, Double_t y1, Double_t rad, Double_t phimin, Double_t phimax, Double_t wl = .02, Double_t amp = .01)
 create a new TCurlyarc with center (x1, y1) and radius rad.
 The wavelength and amplitude are given in percent of the line length
 phimin and phimax are given in degrees.
void Build()
 Create a curly (Gluon) or wavy (Gamma) arc.
Int_t DistancetoPrimitive(Int_t px, Int_t py)
 Compute distance from point px,py to an arc.

  Compute the closest distance of approach from point px,py to this arc.
  The distance is computed in pixels units.
void ExecuteEvent(Int_t event, Int_t px, Int_t py)
 Execute action corresponding to one event.

  This member function is called when a TCurlyArc 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 SavePrimitive(ostream& out, Option_t* = "")
 Save primitive as a C++ statement(s) on output stream out
void SetCenter(Double_t x1, Double_t y1)
 Set Curly Arc center.
void SetRadius(Double_t radius)
 Set Curly Arc radius.
void SetPhimin(Double_t phimin)
 Set Curly Arc minimum Phi.
void SetPhimax(Double_t phimax)
 Set Curly Arc maximum Phi.
void SetDefaultWaveLength(Double_t WaveLength)
 Set default wave length.
void SetDefaultAmplitude(Double_t Amplitude)
 Set default wave amplitude.
void SetDefaultIsCurly(Bool_t IsCurly)
 Set default "IsCurly".
Double_t GetDefaultWaveLength()
 Get default wave length.
Double_t GetDefaultAmplitude()
 Get default wave amplitude.
Bool_t GetDefaultIsCurly()
 Get default "IsCurly".
TCurlyArc(const TCurlyArc& )
{;}
TCurlyArc(Double_t x1, Double_t y1, Double_t rad, Double_t phimin, Double_t phimax, Double_t wl = .02, Double_t amp = .01)
