[求助]AO 新建要素的完成事件

新建了个属性窗体，需要在ArcMap中编辑图层时，添加完新要素后跳出这个窗体，但不知道 ，添加完新要素的响应事件，有高手知道怎么做么？

<P>见意你自己写一个ITool类，实现一下添加的功能和弹出窗口的功能就可以了。很简单。</P>

<P>好象可以新建个编辑任务，用到IEditTask接口，在帮助里也找到个例子</P><PRE><PRE><CODE><PRE>/// <summary><BR><SUMMARY>/// This class implements the IEditTask interface.</PRE>/// The class is registered as a new EditTask and appears as Select Features Using Sketch
