Question

I'M trying to do that but I defined both classes

in the main file and class 'b' need to be defined before class 'a' because class 'a' is using class 'b'.

and know for doing what you said I need to get access from class 'b' to class 'a', and right now class 'b' doesnt know about class 'a'.

what do you suggest - moving both classes to separate files?

usually you have to forward define one of the two. es: class a; class b{ public: void method(a&); }; class a{ public: int f{}; b sub_obj{}; void method(); }; void b::method(a& parent){ parent.f=54; } void a::method(){ sub_obj.method(*this); }
