java - 在 Eclipse 中创建一个透视菜单

Question

我正在开发一个 Eclipse 插件，我想将一个新菜单(与文件、编辑等一起位于屏幕顶部)与我正在创建的透视图相关联。

我做的菜单没问题，但它甚至在其他角度显示。我如何才能将它与我的观点联系起来？这是我在 plugin.xml 中使用的代码:

<plugin>
<extension point="org.eclipse.ui.perspectives">
   <perspective
         class="org.eclipse.ui.articles.perspective.API_Development"
         id="org.eclipse.ui.articles.perspective.API_Development"
         name="API Development">
   </perspective>
</extension>

<extension
         point="org.eclipse.ui.actionSets">
      <actionSet
            label="Sample Action Set"
            visible="true"
            id="API_Development_Menu.actionSet">
         <menu
               label="API Development"
               id="sampleMenu">
            <separator
                  name="sampleGroup">
            </separator>
         </menu>
      </actionSet>
   </extension>
</plugin>

感谢和问候，库尔特

wiki article "Menu Contribution" Eclipse3.3M6以来提到的元素

 <visibleWhen/>

An org.eclipse.core.expressions.definitions extension point was added. Used to define a core expression, the definition can then be referenced from other locations.

<extension point="org.eclipse.core.expressions.definitions">
  <definition id="com.example.context">
    <with variable="activeContexts">
       <iterate operator="or">
         <equals value="org.eclipse.ui.contexts.actionSet"/>
       </iterate>
    <with>
  </definition>
</extension>

This can be called in a core expression like activeWhen, enabledWhen, visibleWhen, etc using the reference element:

<reference definitionId="com.example.context"/>

也许这样的定义:

可以用于您的菜单吗？
