Question

如果第一个菜单的过程完成，我想启用第二个和第七个菜单。如果第二个菜单的处理完成，我想启用第3和第7个菜单，依此类推。我有七个菜单。首先，只有第一个菜单应该是活动的，剩下的应该是禁用的，如果第一个过程完成，则第二个菜单应该只启用第一个菜单，第二个菜单和第7个菜单。

我没有得到如何在我的plugin.xml中进行更改以便按照我的预期工作。这是我的plugin.xml代码。请帮助我，并提前感谢你。

对于每个命令，您可以在enabledWhen上使用handler表达式执行此操作。听起来你可能不得不使用属性测试器来定义表达时启用的自定义测试。

使用org.eclipse.core.expressions.propertyTesters定义属性测试器，例如：

<extension point="org.eclipse.core.expressions.propertyTesters">
  <propertyTester
    id="documentation.propertytester"
    type="java.lang.Object"
    namespace="documentation"
    properties="handler1enabled,handler2enabled,handler3enabled.. and so on ..."
    class="documentation.PropertyTester">
  </propertyTester>
</extension>

然后编写一个documention.PropertyTester类来进行属性测试。

然后您可以在启用时使用它，如下所示：

<handler
        class="documentation.handlers.SampleHandler5"
        commandId="documentation.handlers.SampleHandler5">
     <enabledWhen>
         <test
              property="namespace.handler5enabled">
         </test>
     </enabledWhen>
</handler>
