How can I define a struct in (*.cpp) instead (*.h) in a class

I want to define a struct out of the head file.

Below is what I declare in the (*.h)

class MyVertex
{
public:
    struct Vertex{};
};

How can I define the struct Vertex more detailedly in the (*.cpp)? I've tried several times with several ways but failed.

The problem here is you are not declaring the struct you are fully defining it. In order to declare it you need to leave off the {} 

class MyVertex { 
public:
  struct Vertex;
};

Once you do that you will be able to define the struct members later in the .h file or the .cpp 

struct MyVertex::Vertex { 
  ...
};
