I would like to create a class with a sf::Shape as a member variable, but for some reason i cannot set it's parameters in the default constructor, only in main.

Any idea why, the error says "expression must have class type". Thank you to anyone that can help out.

```
#include "stdafx.h"
#include <SFML/Graphics.hpp>

class SFshape : public sf::Shape
{

public:
    SFshape()
    {
        shape.setSize(sf::Vector2f(100, 100));

    }
private:
    sf::RectangleShape shape();

};

int main()
{
    sf::RenderWindow window(sf::VideoMode(200, 200), "SFML");

    while (window.isOpen())
    {
        sf::Event event;
        while (window.pollEvent(event))
        {
            if (event.type == sf::Event::Closed)
                window.close();
        }

        window.clear();
        window.display();
    }

    return 0;
}

```
