1. 右键单击某些文件类型（资源）在资源视图（或程序包视图）中


2. 右键单击打开文件类型的相应编辑器。它可以检测到我的编辑器是开放的，或者编辑器有一定的资源打开。

我已经完成了第一次使用'visibleWhen '>'selection（with）'>'iterate'>'org.eclipse.core.resources.IResource（adapt）'，然后检查资源的文件扩展名。代码如下。但是，我不知道如何获得相同的命令，只有当您右键单击正确的编辑器，打开一个文件，扩展名为ext1，ext2。

检查我的编辑器是否处于活动状态，解决了第二个问题，但似乎没有帮助，因为如果我点击不是我的类型的文件，它仍将在上下文菜单中显示该命令。

任何建议？
Eclipse插件（第3版）显示了编辑器上下文菜单的一些示例，但它使用动作，我想坚持命令。

谢谢!!

解决方案

我可以使用与变量，我遇到了。使用上面相同的代码示例：

• 添加一个<或> < iterate> 块


• 将现有的< adapt> 阻止新的<或> 块


• 添加一个新的与变量名为 activeEditorInput

这是新的代码示例。

 < iterate ifEmpty =falseoperator =or> 
<或> X-45454545 X- 20045 X- 20045 X- 20045 X- 20045 X- 20045 X- 20045 X- 20045 X- 20045 X- 20045 X- 20045 X- 20045： 
<或> 
 ...测试扩展
< /或> 
< / adapt> 
< with variable =activeEditorInput> 
< adapt type =org.eclipse.core.resources.IResource> 
<或> 
 ...测试扩展
< /或> 
< / adapt> 
< / with> 
< /或> 
< / iterate> 
  

I am trying configure visibility of a command within the context menu using 'visibleWhen' expression within a menuContribution. What I am trying to do is make the command visible in the context menu only if you:

1. Right-click certain file types(resources) in the resource view (or package view)
2. Right-click the appropriate editor that has the file type open. It can detect that my editor is open or that the editor has a certain resource open.

I've accomplished the first using 'visibleWhen'>'selection(with)'>'iterate'>'org.eclipse.core.resources.IResource(adapt)' then checking the file extension for the resource. The code is listed below. However, I'm not sure how to get the same command to only appear when you right-click the correct editor that has a file open with the correct extensions - ext1, ext2.

Checking if my editor is active resolves the second issue but doesn't seem to help since if I click on files that are not my type, it will still show the command in the context menu.

Any recommendations? The "Eclipse Plug-ins (3rd Edition)" shows some example for editor context menu but it uses actions and I want to stick with commands.

Thanks!!

解决方案

I was able to get it done with a with variable that I came across. Using the same code example above:

• Add an <or> block within the <iterate> block
• Place the existing <adapt> block in the new <or> block
• Add a new with variable called activeEditorInput

Here is the new code example.

<iterate ifEmpty="false" operator="or">
  <or>
    <adapt type="org.eclipse.core.resources.IResource">
      <or>
        ...test extensions
      </or>
    </adapt>
    <with variable="activeEditorInput">
      <adapt type="org.eclipse.core.resources.IResource">
        <or>
          ...test extensions
        </or>
      </adapt>
    </with>
  </or>
</iterate>
