I want to inherit the constructor of the base class, but don't compile. How can I solve this problem without changing the class name?
class MyClass
{
public:
class A
{
};
};
class MyClass2 : MyClass
{
public:
class A : MyClass::A
{
//error: expected nested-name-specifier before ‘namespace’
using (MyClass::A)::(MyClass::A);
};
};
using MyClass::A::A;
The constructor is referred to by a qualified name to the base class from which it should be imported, i.e. MyClass::A, and then again the class name to refer to the constructor, but only the class name, not a qualified name, i.e. A.
Does using MyClass::A::A; do what you want?
If you want to use method() from class MyClass::A, you have to write using MyClass::A::method;. In your case, method() is the constructor, named A().
