SDL_WINDOWEVENT_RESIZED 对比 SDL_WINDOWEVENT_SIZE_CHANGED

Question

在 SDL 中，这两个 window 事件有什么区别？

SDL_WINDOWEVENT_RESIZED
SDL_WINDOWEVENT_SIZE_CHANGED

在 wiki 文档页面中有 this 代码示例：

    case SDL_WINDOWEVENT_RESIZED:
        SDL_Log("Window %d resized to %dx%d",
                event->window.windowID, event->window.data1,
                event->window.data2);
        break;
    case SDL_WINDOWEVENT_SIZE_CHANGED:
        SDL_Log("Window %d size changed to %dx%d",
                event->window.windowID, event->window.data1,
                event->window.data2);
        break;

但我看不出有什么不同。

Answer 1

来自the SDL Wiki：

SDL_WINDOWEVENT_RESIZED

window has been resized to data1 x data2; this event is always preceded by SDL_WINDOWEVENT_SIZE_CHANGED

SDL_WINDOWEVENT_SIZE_CHANGED

window size has changed, either as a result of an API call or through the system or user changing the window size; this event is followed by SDL_WINDOWEVENT_RESIZED if the size was changed by an external event, i.e. the user or the window manager
