使用 GWT 的 GMail 类似于文件上传进度条? [英] GMail like file upload progress bar with GWT?

问题描述

所有 Gmail 用户应该已经注意到最近更新了文件上传进度条.

All Gmail users should have already noticed that file upload progress bar has been updated recently.

我想知道 GWT 是否可以实现这种效果.我对 GWT 还很陌生，所以如果有任何 GWT 源代码可以帮助我测试该功能，将会非常有帮助.

I'm wondering such effect is possible to implement with GWT. I'm fairly new with GWT, so if any GWT source code that can help me test out the function would be very helpful.

Update
I ended up going with SWFUpload. However, other suggestions under this question are all valid. Just try different options and choose the one you like!

推荐答案

看看这个库:http://code.google.com/p/gwtupload/.它非常易于使用并且在我检查过的所有浏览器和操作系统中都可以正常工作.它使用 ajax 请求来计算进度.顺便说一句，Swfupload 在 linux 和 Mac 中表现不佳.

Take a look to this library: http://code.google.com/p/gwtupload/. It is really easy to to use and works fine in all browsers and OS I've checked. It uses ajax requests to calculate progress. BTW Swfupload doesn't do well in linux and Mac.
