setFramerateLimit(x) vs. setVerticalSyncEnabled(true)

[FRex]

How do these two work together in a RenderWindow, mainly:
1. If both were called, is the limit used the the smaller/bigger one of them two, or one that was put on the screen with last call or something else?

2. Is there a way to get max fps that these two permit RenderWindow to have?

3. If setVerticalSyncEnable(true) is called first, then setFramerateLimit(x) with x being smaller than max fps permitted by vertical sync and then setFramerateLimit(0) is called, is limit now again what vertical sync permits or there is no limit at all?

You should read the tutorial ("Controlling the framerate" section).

Would class like this be safe?

class SafeRW : public sf::RenderWindow
{
public:
        SafeRW(void);
        SafeRW(sf::WindowHandle handle,const sf::ContextSettings& settings = sf::ContextSettings()):
        sf::RenderWindow(handle,settings){}
        SafeRW(sf::VideoMode mode,const std::string& title,sf::Uint32 style = sf::Style::Default, const sf::ContextSettings& settings = sf::ContextSettings()):
        sf::RenderWindow(mode,title,style,settings){}
        virtual ~SafeRW(void){};
        void setFramerateLimit(unsigned int limit)
        {

                sf::RenderWindow::setVerticalSyncEnabled(false);
                sf::RenderWindow::setFramerateLimit(limit);
        }
        void setVerticalSyncEnabled(bool enabled)
        {
                sf::RenderWindow::setFramerateLimit(0);
                sf::RenderWindow::setVerticalSyncEnabled(enabled);
        }
};

Hmm yes. But do you really need such a class? Is it really too hard to not activate both in your program?

[FRex]

Well not really anymore. But there was part of code that I wanted to limit to lower framerate because of amount of sf::VertexArrays stored in vector of vectors with 1 quad each but I changed that part now.
