Can someone please give an example how to implement the copy constructor correctly in the base and derived class? I spent some hours to find out how it could work and I'm doing it like this:

Base(const Base &other)

: d_ptr(new BasePrivate(other.d_func()->property1,

{ }

Derived(const Derived &other)

: Base(*new DerivedPrivate(other.d_func()->property1,
   other.property2, other.d_func()->property3....))

{ }

It works but somehow it doesn't feel like it was meant that way.
