const int WIDTH = 600;
const int HEIGHT = 600;

void SDLExample() {
    if (SDL_Init(SDL_INIT_EVERYTHING) < 0) { std::cout << "初始化失败" << std::endl; }
    SDL_Window *window = SDL_CreateWindow("Skia + SDL", SDL_WINDOWPOS_CENTERED, SDL_WINDOWPOS_CENTERED, WIDTH, HEIGHT,
                                          SDL_WINDOW_ALLOW_HIGHDPI);
    if (window == nullptr) { std::cout << "创建Window失败" << std::endl; }
    SDL_Event windowEvent;
    while (true) {
        if (SDL_PollEvent(&windowEvent)) {
            if (windowEvent.type == SDL_QUIT) {
                std::cout << "终止程序" << std::endl;
                break;
            }
        }
    }
    SDL_DestroyWindow(window);
    SDL_Quit();
}

基本的步骤

1. 初始化

2. 创建Window

3. 监听输入事件

4. 监听到关闭事件的时候销毁Window并离开
