Problem with sf::NonCopyable

[blargly]

I'm currently trying to put together an object manager class for game which has an update method which draws each of the sprites in the game. In order to do this, I needed an sf::RenderWindow object to be passed to my object manager and then draw each sprite.
However, when I pass my window I get the following error:

error C2248: 'sf::NonCopyable::operator =' : cannot access private member declared in class 'sf::NonCopyable'

I made sure that only references were being passed, but the same error still occurs, which I thought to be odd considering a reference isn't an actual copy.

Code: [Select]

int main()
{
    // Create main window
    sf::RenderWindow App(sf::VideoMode(800, 600), "SFML Pong", sf::Style::Fullscreen);

ObjManager OMan(App);

Code: [Select]

ObjManager::ObjManager(sf::RenderWindow& App)
{

}

Sorry if I've made some rookie errors here, I'm still a relatively new programmer, and I've just started getting into using libraries like SFML in order to implement graphics into my games.

I don't see an error in the code you've posted. Could you show us the class definition of ObjManager?

Code: [Select]

class ObjManager
{
public:
ObjManager(sf::RenderWindow& App);
~ObjManager();

sf::RenderWindow LocWindow;

void AddObject();
void Update();

std::list<Player>m_PlayerList;

};

Just to note Player is a class which inherits from sf::Sprite but the same issue occurs even if everything bar the constructor is commented.

Are you sure that ObjManager needs an own, independent instance of sf::RenderWindow? Or did you just forget the reference (&)?

Code: [Select]

class ObjManager
{
                ...
sf::RenderWindow LocWindow;
                ...
};
I guess you have got something like the following in your code, which isn't valid since sf::RenderWindow is noncopyable.

Code: [Select]

LocWindow = App
After declaring LocWindow as reference, use the initializer list in your constructor:

Code: [Select]

ObjManager::ObjManager(sf::RenderWindow& App)
: LocWindow(App)
{
}

Code: [Select]

LocWindow = App

Yeah that's right, I was using the above, and ObjManager was using its own independent instance of sf::RenderWindow.
Ok, just made the changes and the problem is solved, many thanks!
