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,
    other.d_func()->property2...)
{
}
 
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.
