刚学Java，搞不懂Pane和Panel的区别在哪里，看来以英语为母语的人群学编程还是比较有优势的。
百度一下，找到了一篇博文对二者有明确的阐述，可惜拒接转载，也许博主不崇尚开源：http://simon.blog.51cto.com/80/122148
这里大致说下我的理解。
Pane指的是一个独立窗口中的窗格，比如.CHM帮助文档中左边一个索引窗格，右边一个正文窗格；再比如Eclipse左边一个包资源管理器窗格，中间一个编辑器窗格等等。
Panel指的是一个面板，用它来对一些控件进行分组，就像组合框控件，即Visual Studio里面用的Group Box Control；而在一些软件界面里面也可以表现为工具条，比如编辑工具条、文件工具条、绘图工具条等等（其实这些工具条在开发实现上是一些窗口，即主窗口中的子窗口，学习过WIN32 API编程的朋友会更好理解）。
引用一下上面博文中被引用的英文说明，应该不算转载吧！
A pane is a (usually) independently scrollable subsection of a window. It's what you get, for example, if you drag the splitter bar in a Word window.
A panel is an object that is used to group controls and other objects. It is often but not always dragable, occasionally resizable or scrollable. Most toolbars, for example, consist of a panel with buttons. Panels may or may not have a visible border.
