Passing a render window to a class?

[Xenavar]

What is the correct syntax to do that? In both the .h and .cpp. because right now I am getting the following error:

C:\Users\Steven\Desktop\SFML-1.5\include\SFML\System\NonCopyable.hpp|57|error: `sf::NonCopyable::NonCopyable(const sf::NonCopyable&)' is private|

followed by:

C:\Users\Steven\Desktop\RPG\main.cpp|21|error:   initializing argument 2 of `void PC::Handle_event(sf::Event, sf::RenderWindow)'|

I believe this is known as passing by reference. Could be that it's not though...

Anyway, it works:

Code: [Select]

void CLASS::draw(sf::RenderWindow &target)
{
    target.Draw(sprite);
}


To call it:

Code: [Select]

class.draw(App);

Obviously, you might not be doing this for a drawing routine, but you should be able to see how it works.

Is there a reason that when I pass a window to a class and then use events that use the window's elapsed time to make a sprite move, it has some lag spikes?

The first time I did it I had no classes at all and it worked perfecly fine on a normal function (in main)

Not at all. What's the code?
