Thread: Problem constructing a class with a nested struc

I am trying to pass a nested struct type as an argument for the class constructor, and use an initializer list to invoke the implicit copy constructor for the struct to do all the work. But it's somehow not working.

This is my header file

Code:

#ifndef _OBJECT_HPP_
#define _OBJECT_HPP_

class Object
{
public:

	// Nested structure to represent a point and its corresponding operations
	struct Point {
		float x, y;

		// Struct constructor
		Point ( float X = 0, float Y = 0 );

		// Way to set the point
		void Set ( float X, float Y );

		// The origin
		static const Point ORIGIN;
	};
	
	// Constructor
	Object ( const Point & center );

	// Function for viewing and setting the center of the object
	Point & Center ();

	// Function for returning the area, a pure virtual function
	virtual float Area() const = 0;

	// Drawing function
	virtual void Draw ();
	
	// Destructor
	virtual ~Object();


private:
	Point center;
};
#endif

and this is my implementation of the class

Code:

#include "Object.hpp"

const Object::Point Object::Point::ORIGIN = Object::Point();

// Point constructor
Object::Point::Point ( float X, float Y )
{
	x = 0;
	y = 0;
}

// Set function
void Object::Point::Set ( float X, float Y)
{
	x = X;
	y = Y;
}

// Object constructor (default and non-default)
// Use implicit copy constructor
Object::Object ( const Point & center ) : Point(center)
{
}

// Function for returning the area, a pure virtual function
float Object::Area() const
{
}

// Drawing function
void Object::Draw ()
{
}
	
// Destructor
Object::~Object()
{
}

The red part is where I am having problem, when I tried to compile I got this message

Code:

error C2436: 'Point' : member function or nested class in constructor initializer list

Does a struct come with a default copy constructor or do I need to define it separately?
Please advice, thanks.
