由于主界面其实就是 Chrome 的浏览器窗口，所以沿袭了它的一些行为，例如将外部文件拖进窗口时，node-webkit 会尝试打开文件比如如果文件是图片，那么主窗口就会直接显示出这张图片，如果不禁用这个行为的话实在太容易穿帮了。

其实拖放（drag-drop）操作是Html5的功能，不是nw.js的内置API，那么我们采用Html5应用一般的处理方法就可以了。

首先我们看一下一个正常的页面，直接拖放一个文件过来的效果。

页面代码：

<html>
 <head> 
  <title>拖放测试</title> 
 </head> 
 <body>
  <bodystyle="background-color:rgba(0,0,0,0);"> 
   <pid="output"> 
    <h1 id="拖放测试">拖放测试</h1> 
    <p></p> 
    <script>

</script>  
   </pid="output">
  </bodystyle="background-color:rgba(0,0,0,0);">
 </body>
</html>
