c++ - Complex class and pointer

Question

I try to understand to many complex as class, as in this code example :

class System
{
    int info;

    public:
      System *parent;
      System() {info = 0; parent=0;}
};

class Window
{
    public:
      Window();
};

class SoftWindow : public Window
{
     protected:
       System *systemWindow;
       Window *parent;

     public:
       Softwindow();
};

In System *parent I would like to understand what it does mean this pointer object in the same class System? Same here in the class Softwindow for System *systewindow ? What it does mean two pointer System in separation from class ? Can I assign with the pointer System *systemWindow to pointer System *parent even from two different class ?

Thanks
