inherit member variable using proxy

[MQN-80]

How do I inherit member variable if I have a Drawable class with two variable width and height, then Rectangle and circle want to inherit it

proxy only supports functions. It is not designed to support fields or nested types.

if I want to use base class's variable,so i still need to inherit the base class ?

Assuming you are using proxy 2.4.0, you can define a member function (like .size()) or free function (like std::size()) to retrieve a field of a type, and wrap the functions with PRO_DEF_MEMBER_DISPATCH or PRO_DEF_FREE_DISPATCH, and define a facade with the dispatch.
