Question

我正在使用SDL的最新版本,即SDL_WINDOWEVENT似乎失踪。

在SDL_Events.h内部,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;

我知道有一个SDL。 WINDOWEVENT from the wiki

澄清问题

如果你看看所提供的联系,则样本代码显示

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
}

My Code

    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
            }
        }
    }

error C2065: SDL_WINDOWEVENT : undeclared identifier error C2039: window : is not a member of SDL_Event sdl_events.h(227) : see declaration of SDL_Event error C2228: left of .event must have class/struct/union error C2065: SDL_WINDOWEVENT_MOVED : undeclared identifier

我发现,我的问题——Joachim和用户1202136使我解冻。

我使用的SDL版本错了,这解释了为什么没有这种方法。
