133 这里类就是核心部分了，用来操作keyassit,keyassit包括两部分的，一是在plugin.xml里定义的，和在runtime时动态加入的。
eclipse 已经提供了取得plugin.xml里keyassist item，的功能。需要实现的是runtime的功能。
典型的应用是在当前画面中搜索带快捷键的button,哇这个功能看上去有点bt,实际上也是很简单的。

118 这个类就是为了parser 介面而写的。利用递归可以很简单的遍历所以界面中的控件
1package com.hactl.eaf.ui.rich.composite.widget.keyassist;

3public class WidgetInfo {
4 private String commandId;
5
6 private String text;
7
8 private String shortkey;
9
10 public String getCommandId() {
11 return commandId;
12 }
13
14 public void setCommandId(String commandId) {
15 this.commandId = commandId;
16 }
17
18 public String getShortkey() {
19 return shortkey;
20 }
21
22 public void setShortkey(String shortkey) {
23 this.shortkey = shortkey;
24 }
25
26 public String getText() {
27 return text;
28 }
29
30 public void setText(String text) {
31 this.text = text;
32 }
33
34}
35 最后的这个就是parser后返回的结果的类型。
