Question

我使用的是最新版本的SDL，enum SDL_WINDOWEVENT似乎缺失了

在SDL_Events.h中，SDL_Events的定义是：

/** General event structure */
typedef union SDL_Event {
    Uint8 type;
    SDL_ActiveEvent active;
    SDL_KeyboardEvent key;
    SDL_MouseMotionEvent motion;
    SDL_MouseButtonEvent button;
    SDL_JoyAxisEvent jaxis;
    SDL_JoyBallEvent jball;
    SDL_JoyHatEvent jhat;
    SDL_JoyButtonEvent jbutton;
    SDL_ResizeEvent resize;
    SDL_ExposeEvent expose;
    SDL_QuitEvent quit;
    SDL_UserEvent user;
    SDL_SysWMEvent syswm;
} SDL_Event;

我知道wiki有一个SDL_WINDOWEVENT

http://wiki.libsdl.org/moin.cgi/SDL_WindowEvent?highlight=%28%5CbCategoryStruct%5Cb%29%7C%28CategoryEvents%29%7C%28SGStructures%29

编辑以澄清问题

如果查看提供的链接，示例代码会给出

void PrintEvent(const SDL_Event * event)
{
    if (event->type == SDL_WINDOWEVENT) {
        switch (event->window.event) {
        case SDL_WINDOWEVENT_SHOWN:
            fprintf(stderr, "Window %d shown", event->window.windowID);
            break;
// snip
}

我的代码

    SDL_Event sdlEvent = {0};

    while(SDL_PollEvent(&sdlEvent))
    {
        if(sdlEvent.type == SDL_QUIT)// || isTriggered(SDLK_ESCAPE))
            System::getEventManagerGlobal().broadcastEvent( Event("QUIT") );
        if(sdlEvent.type == SDL_WINDOWEVENT)
        {
            if(sdlEvent.window.event == SDL_WINDOWEVENT_MOVED)
            {
                // snip
            }
        }
    }

错误C2065：'SDL_WINDOWEVENT'：未声明的标识符错误C2039：'window'：不是'SDL_Event'的成员 sdl_events.h（227）：查看'SDL_Event'的声明错误C2228：'。event'的左边必须有class / struct / union 错误C2065：'SDL_WINDOWEVENT_MOVED'：未声明的标识符

我发现了我遇到的问题 - Joachim和user1202136让我觉得

我误解了我正在使用的SDL版本，这解释了为什么这些方法不存在..
