class TCurlyLine: public TPolyLine


 This class implements curly or wavy polylines 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 TPolyLine by inheritance, ExecuteEvent methods
 are highly inspired from the methods used in TPolyLine and TArc.

Function documentation

TCurlyLine()

 Default constructor.

TCurlyLine(Double_t x1, Double_t y1, Double_t x2, Double_t y2, Double_t wl = .02, Double_t amp = .01)

 Create a new TCurlyLine with starting point (x1, y1), end point (x2,y2).
 The wavelength and amplitude are given in percent of the pad height.

void Build()

 Create a curly (Gluon) or wavy (Gamma) line.

Int_t DistancetoPrimitive(Int_t px, Int_t py)

 Compute distance from point px,py to a line.

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

 Execute action corresponding to one event.

  This member function is called when a  TCurlyLine 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 SetCurly()

 Set curly.

void SetWavy()

 Set wavy.

void SetWaveLength(Double_t WaveLength)

 Set wave length.

void SetAmplitude(Double_t x)

 Set amplitude.

void SetStartPoint(Double_t x1, Double_t y1)

 Set start point.

void SetEndPoint(Double_t x2, Double_t y2)

 Set edn point.

void SetDefaultWaveLength(Double_t WaveLength)

 Set default wave length.

void SetDefaultAmplitude(Double_t Amplitude)

 Set default amplitude.

void SetDefaultIsCurly(Bool_t IsCurly)

 Set defaul "IsCurly".

Double_t GetDefaultWaveLength()

 Get default wave length.

Double_t GetDefaultAmplitude()

 Get default amplitude.

Bool_t GetDefaultIsCurly()
