i want define struct out of head file.
below declare in (*.h)
class myvertex { public: struct vertex{}; }; how can define struct vertex more detailedly in (*.cpp)? i've tried several times several ways failed.
the problem here not declaring struct defining it. in order declare need leave off {}
class myvertex { public: struct vertex; }; once able define struct members later in .h file or .cpp
struct myvertex::vertex { ... };
