首先，在非静态成员函数中有一个隐式的this"指针，所以你需要改变你的void myDisplay()ClassBlah 中的/code> 是静态的.解决这个限制很尴尬，这就是为什么 C++ faq lite 说 不要这样做

Firstly, there is an implicit "this" pointer in non-static member functions, so you'll need to change your void myDisplay() in ClassBlah to be static. It's awkward to work around this limitation, which is why the C++ faq lite says don't do it

然后，您应该可以将函数作为 ClassBlah::myDisplay 传递.

Then, you should be able to pass the functions as ClassBlah::myDisplay.

根据您重载的动机(即您是要在运行时热交换进出实现，还是仅在编译时?)您可能会考虑一个实用程序处理程序"静态类，其中包含指向您的基类的指针，并且通过这种方式委派责任.

Depending on your motivation for overloading (ie are you going to hotswap implementations in and out at runtime, or only at compile time?) you might consider a utility "handler" static class that contains a pointer to your base class, and delegates responsibility through that.
