 | I'd to change the visibility of a method overrided from public to private but it doesn't work tho to protected it does. Why is that? give: this is ok: this is not: Why is that? why must I leave it accessible somehow (even if it's protected) to all derived class of my derived class? | |||

Can you begin protected instead? 🤔 | |||

Private member functions are implicitly final and cannot be overridden. | |||

This is (slightly) different, as he's not overriding private member functions. He's overriding public functions, and marking them as private.
I think the issue is more that private functions are not allowed to be in the vtable (which is not exactly what the text says).
Besides, it would be weird to mark a public function private in a derived type. All that is required is to cast to the base class and then you can call it.
I swear I read a bug that discusses this exact issue...
