如何在SDL中检查或检测窗口是否最小化或未激活？

#include <SDL.h>

int main(int argc, char* argv[])
{
    SDL_Init(SDL_INIT_VIDEO);

    SDL_Window* window = SDL_CreateWindow("Window", SDL_WINDOWPOS_UNDEFINED, SDL_WINDOWPOS_UNDEFINED, 800, 600, SDL_WINDOW_SHOWN);

    // 主循环
    bool quit = false;
    while (!quit)
    {
        SDL_Event event;
        while (SDL_PollEvent(&event))
        {
            if (event.type == SDL_QUIT)
            {
                quit = true;
            }
        }

        // 检查窗口状态
        Uint32 flags = SDL_GetWindowFlags(window);
        bool minimized = (flags & SDL_WINDOW_MINIMIZED) != 0;
        bool inactive = (flags & SDL_WINDOW_INPUT_FOCUS) == 0;

        if (minimized)
        {
            // 窗口最小化
            // 执行相应的操作
        }

        if (inactive)
        {
            // 窗口未激活
            // 执行相应的操作
        }

        // 其他逻辑...

        SDL_Delay(100);
    }

    SDL_DestroyWindow(window);
    SDL_Quit();

    return 0;
}
