如何在SFML 2.5中调整窗口大小时保持窗口的纵横比？

#include <SFML/Graphics.hpp>

int main()
{
    sf::RenderWindow window(sf::VideoMode(800, 600), "SFML Window");

    // 获取当前窗口的宽度和高度
    float currentWidth = window.getSize().x;
    float currentHeight = window.getSize().y;

    // 所需的纵横比
    float targetAspectRatio = 16.0f / 9.0f;

    // 计算新的窗口宽度和高度
    float newWidth = currentWidth;
    float newHeight = currentHeight;

    if (currentWidth / currentHeight > targetAspectRatio)
    {
        newWidth = currentHeight * targetAspectRatio;
    }
    else
    {
        newHeight = currentWidth / targetAspectRatio;
    }

    // 计算窗口的偏移量
    float offsetX = (currentWidth - newWidth) / 2.0f;
    float offsetY = (currentHeight - newHeight) / 2.0f;

    // 创建新的窗口模式对象
    sf::VideoMode newVideoMode(newWidth, newHeight);

    // 重新创建窗口
    window.create(newVideoMode, "SFML Window");

    // 更新视图以适应新的窗口大小
    sf::View view(sf::FloatRect(0, 0, newWidth, newHeight));
    view.setViewport(sf::FloatRect(0, 0, 1.0f, 1.0f));
    window.setView(view);

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

        window.clear();
        // 在这里绘制你的内容
        window.display();
    }

    return 0;
}
