  how to generate class with virtual functions using nim, like this?

   Myclass
  {
  public:
          virtual void Setup()
          {
          }
          virtual void Start()
          {
          }
          virtual void Stop()
          {
          }
  }; 
  Run

  it seems to have written about it here, but I don't understand anything https://github.com/nim-lang/Nim/wiki/Playing-with-CPP--VTABLE-from-Nim

  The wiki page you're linking to is an advanced concept to use C++ VTable from NIM, i.e. it's foreign function interface, not pure Nim.

  The equivalent of virtual function in Nim are methods, the base type should be a ref MyBase of RootObj and it can be inherited with a ref MyClass of MyBase.

  See tutorial on dynamic dispatch.
