IPartListener2的用法参看:<br><a href=http://www.mamicode.com/"http://www.blogjava.net/raul/archive/2008/01/04/172761.html">http://www.blogjava.net/raul/archive/2008/01/04/172761.htmlh<br></a><a href=http://www.mamicode.com/"http://blog.csdn.net/cuser_online/article/details/7947527">http://blog.csdn.net/cuser_online/article/details/7947527</a><a href=http://www.mamicode.com/"http://www.blogjava.net/raul/archive/2008/01/04/172761.html"><br></a>IIPartListener的应用场景？<br>IPartListener监听WorkbenchPart(包括ViewPart和EditorPart)和生命周期(打开，隐藏，关闭等)，<br>当我们想在某WorkbenchPart在这些生命周期发生的触发点上做些事情的时候，此接口正好为你所用。<br>IPartListener2是IPartListener的一个替代类，其支持的事件更多一些。
