这篇博客对比了SWT和Swing在GUI开发中的优缺点，强调了SWT如何方便地集成Word和IE。作者通过示例代码展示了如何在SWT中创建一个可以打开和保存Word文档的应用，并提到了寻找OLEView的相关信息。

swing的先天缺陷,jeditpane功能具弱,想用word还得用jacob,而且只能控制没有编辑控件.
swt就好多了, word,IE想用什么直接调就行了,看来以后要多留意swt了.

闲话少说,把我做的测试程序贴上(初学swt,用Designer做的界面,核心代码都是网上抄来的).
说实话,我觉得swt的实现方式真的没swing舒服,高手不要笑我.

另那里有下vs2003的oleview,不知道有人知道吗?
