Class Design with Virtual Methods

Question

How can someone solve such a problem with classes and enter at least the maximum possible code? That's what i

Basic interface for everything

    class IWindow
    {
    public: 
        virtual void Refresh() = 0;
// another 100 virtual methods
// ...
    };

This interface is used inside a library that has no idea about a particular implementation.

Here is a specific implementation version

    class ConcreteWindow : public IWindow
    {
    public:
        void Refresh() override {}
/// the other 100 overridden methods 
    };

Now we have another interface that adds some additional methods, and is also used inside this library.

class IDBDetail : public IWindow
{
public:
    virtual void DoDetail() = 0;

};

and here is the main problem when we create a specific inmplementation for it

class IGDBDetailWrapper : public IDBDetail, public ConcreteWindow
{
public :
    void DoDetail() {}
};

. , IDBDetail IWindow , :

    class IWindow
    {
    public:

    class ConcreteWindow : virtual public IWindow
    {
    public:
        void Refresh() override {}
/// the other 100 overridden methods 
    };

class IDBDetail : virtual public IWindow
{
public:

Answer 6

, :

class IGDBDetailWrapper : public IDBDetail, public ConcreteWindow
{
public:
    virtual void DoDetail() override { /*work here*/ }

    virtual void Refresh() override { ConcreteWindow::Refresh(); }
    //another 100 methods
};
