我正在使用代码加载图像(请参见下文)我通过stackoverflow找到了.但是,我现在注意到"getWidget()"已被弃用.而不是等到这个不再可用,我想现在解决这个问题.我该怎么用而不是"getWidget()"？

// Add a finish handler which will load the image once the upload finishes
            existingdefaultUploader.addOnFinishUploadHandler(onReplaceFinishUploaderHandler);
            existingdefaultUploader.getFileInput().getWidget().setStyleName("customButton");
            existingdefaultUploader.getFileInput().getWidget().setSize("100px", "20px");

问候,

我正在寻找一种方法来使用google web toolkit进行文件上传,使用自定义进度条.不寻找显示自己进度条的插件,我宁愿寻找能调用我的回调方法并通知它进度的东西,所以我可以展示自己的进度条.

如果那是不可能的,那么我想知道如何访问HTML5文件API,以便我可以构建自己的文件上传器小部件.

有任何想法吗？

谢谢.
