我正在开发eclipse以创建2个新按钮,如果单击该按钮,将打开一个配置窗口,其中包含简单的2个选项:1.input目录后跟browse,2.output目录后跟browse选项 . 我通过以下plugin.xml文件中的代码在工具栏上创建了2个新按钮

<extension
         point="org.eclipse.ui.actionSets">
      <actionSet
            label="Perspectives and Views Toolbar"
            visible="true"
            id="PerspectivesViewsToolbar.actionSet">
         <action
               class="perspectivesviewstoolbar.actions.ShowViewsPulldownMenuAction"
               icon="icons/views.gif"
               id="PerspectivesViewsToolbar.ViewsPulldownAction"
               label="file1"
               style="push"
               toolbarPath="PerspectivesViewsToolbar/additions"
               tooltip="Show Views">
         </action>
         <action
               class="perspectivesviewstoolbar.actions.ShowPerspectivesPulldownMenuAction"
               icon="icons/perspectives.gif"
               id="PerspectivesViewsToolbar.PerspectivesPulldownAction"
               label="file2"
               style="push"
               toolbarPath="PerspectivesViewsToolbar/additions"
               tooltip="Show Perspectives">
         </action>
      </actionSet>
   </extension>

它将在eclipse的工具栏上创建2个新按钮file1和file2 . 但是,当我点击这些按钮时,我无法打开配置窗口 . 我正在研究eclipse indigo版本 .
