I suspect that the Qt framework only allows inheritance directly from the abstract base class. At least, that seems to be the case in practice, as noted.
"Qt framework" has nothing to do with this. C++ enforces some rules but it is perfectly valid to inherit from an implementation of a pure abstract class.
class Interface {
public:
virtual void func1() = 0;
virtual void func2() = 0;
};
class Implementation : public Interface {
public:
void func1() { printf("Implementation::func1();\n"); }
void func2() { printf("Implementation::func2();\n"); }
};
class Inherited : public Implementation {
public:
void func2() { printf("Inherited::func2();\n"); }
};
class Interface {
public:
virtual void func1() = 0;
virtual void func2() = 0;
};
class Implementation : public Interface {
public:
void func1() { printf("Implementation::func1();\n"); }
void func2() { printf("Implementation::func2();\n"); }
};
class Inherited : public Implementation {
public:
void func2() { printf("Inherited::func2();\n"); }
};

You can do the same with Qt plugins, only that you have to remember you should inherit from QObject somewhere.
Plugin Adapter Classes?
