从类返回渲染窗口

Question

我有点卡住了我如何从我的类返回我的渲染窗口，不知道如果我有返回类型错误或语法或两者兼而有之！

我的main.cpp有：

Window Render(800, 600, "Test"); 
sf::RenderWindow window = Render.Init(); 

我对这个类是：

 Window::Window(int x, int y, std::string title){ 
      ResoX = x; 
      ResoY = y; 
      Title = title; 
     } 

    sf::RenderWindow Window::Init(){ 
     return screen(sf::VideoMode(ResoX,ResoY,Title)); 
    } 

该类头：

class Window 
{ 
    private: 
     int ResoX, ResoY;    
     std::string Title; 
     sf::RenderWindow screen; 
    public: 
    Window(int, int, std::string); 

    sf::RenderWindow Init(); 
}; 

我的错误是：

error C2665: 'sf::VideoMode::VideoMode' : none of the 3 overloads could convert all the argument types could be 'sf::VideoMode::VideoMode(unsigned int,unsigned int,unsigned int)' while trying to match the argument list '(int, int, std::string)'

error C2064: term does not evaluate to a function taking 1 arguments

是否有任何人知道我该如何解决这一问题？

从SFML文件（http://www.sfml-dev.org/documentation/1.6/classsf_1_1VideoMode.php#a9478572db06121f70260e6b9dc21704e）

SF ::：视频模式构造函数声明为：

sf::VideoMode::VideoMode(unsigned int ModeWidth, 
         unsigned int ModeHeight, 
         unsigned int ModeBpp = 32 
         ) 

这意味着你可以不通过第三个参数为字符串，你可以把它叫做：

return screen(sf::VideoMode(ResoX,ResoY));
