SFML pass renderwindow

Im trying to make a game with the SFML.

I'm making a sf::RenderWindow but when I try to pass the window to another class it fails. I can't access the window. Because I think it's good to make a separate class for handling events like 'close the window' etc. but then I can't access it. How can I fix this?

RenderWindow *window;  
window = new RenderWindow(VideoMode(768, 614), "Tower Defence ver 2.0");

try this

class Foo
{
 public:
    Foo(sf::RenderWindow& ptrwindow)
     : ptrwindow(ptrwindow)
    {
          // your code here
    };
    sf::RenderWindow* window()
    {
         return &this->ptrwindow;
    }

  private:
        sf::RenderWindow ptrwindow;
};

int main()
{
 sf::RenderWindow* mywindow = new sf::RenderWindow()
 Foo myfoo(*mywindow);
 myfoo.window()->create(sf::VideoMode(768, 614), "Tower Defence ver 2.0")
}

Create yourself a header file and define your function like so

Header file

#pragma once

#include "SFML/Graphics.hpp"

class MyClass
{
public:
    sf::Sprite Sprite;

    MyClass();
    void Setup(sf::Texture& texture);
    void Draw(sf::RenderWindow& window);
};

Cpp file

#include "Bullet.h"

MyClass::MyClass()
{

}

void MyClass::Setup(sf::Texture& texture)
{
    Sprite.setTexture(texture);
    Sprite.setPosition(0, 0);
}

void MyClass::Draw(sf::RenderWindow& window)
{
    window.draw(Sprite);
}

Then in your game loop for drawing you can call something like this

// myClass is an object of type MyClass
// renderWindow is your sf::RenderWindow object
myClass.Draw(renderWindow);

Hope this helps. Let me know if you need any more guidance.

Which version of SFML are you using? This is not possible in SFML 1.6, but is in SFML 2.0 (upcoming version).

RenderWindow is in a namespace 'sf'

Maybe you have somewhere "using namespace sf;" and it's missing in other places.

Try prefixing it with sf::RenderWindow everywhere.
