13\ingroup BasicGraphics
14
15Implements curly or wavy arcs used to draw Feynman diagrams.
16
17Amplitudes and wavelengths may be specified in the constructors,
18via commands or interactively from popup menus.
19The class make use of TCurlyLine by inheritance, ExecuteEvent methods
20are highly inspired from the methods used in TPolyLine and TArc.
21The picture below has been generated by the tutorial feynman.
