If the browser is capable of handling file uploads using a modern HTML5 approach, the upload is handled using pure DOM elements and Javascript events. 如果浏览器能够使用现代HTML5方法处理文件上载，则使用纯DOM元素和Javascript事件处理上载。 In the case that the browser does not support the modern approach (most notably IE 9 and earlier), the GWT Uploader component instead transparently handles the uploads via the Flash-based SWFUpload library. 在浏览器不支持现代方法（最着名的是IE 9及更早版本）的情况下，GWT Uploader组件通过基于Flash的SWFUpload库透明地处理上传。

I have no problems with it, and it doesn't appear to use flash with any modern browser due the HTML5 support. 我没有任何问题，由于HTML5的支持，它似乎没有使用任何现代浏览器的闪存。 Didn't take me to long to get it added myself and integrated as they have pretty good documentation. 我没有花很长时间把它添加到自己并集成，因为他们有很好的文档。
