如果想要在flex加载pdf，虽然pdf格式是开源的，但是自己去解析太麻烦了，pdf还要分页之类的，现在网上各种文档上传可以在线看很多都是pdf，当然也有word，excel之类，其实很多都是转了swf，flex加载swf，这次只说加载pdf，首先先下载一个swftools，这个工具有命令行可以转pdf 到dwg 简单命令是 pdf2swf -o 1.swf -s flashversion=9 1.pdf，其中flashversion最好选9以上 ，低版本有时候导出swf flex加载不出来。github上有flexpaper这个组件，flexpaper这个组件就不不细说了，还要结合flex-iframe.swc这个组件来用，flexpapaer和flex-iframe.swc地址http://files.cnblogs.com/files/haibalai/FlexPaper.rar。

这里做成一个组件，熟悉flexview开发的都知道widget模式，这里xml格式

1 <?xml version="1.0" encoding="utf-8"?>
2 <data>
3   <pdfname="aaa"url="http://locahost/FlexPaper/index.html?fileSrc=aaa.pdf"></pdf>
4   <pdfname="bbb"url="http://locahost/FlexPaper/index.html?fileSrc=bbb.pdf"></pdf>
5 </data>

组件：
