如何在SFML中使窗口始终在最上面？

#include <SFML/Graphics.hpp>

int main()
{
    sf::RenderWindow window(sf::VideoMode(800, 600), "Always on Top", sf::Style::None);
    window.setFramerateLimit(1000); // 设置帧率限制为一个非常高的值

    while (window.isOpen())
    {
        sf::Event event;
        while (window.pollEvent(event))
        {
            if (event.type == sf::Event::Closed)
                window.close();
        }

        // 渲染窗口内容
        window.clear();
        // ...
        window.display();
    }

    return 0;
}
