Hi,

I am working on an application in which I need to add an action to
context menu of editor. However, this action should be visible only for
external editors (i.e. for editing files which are external to the
workspace).
In my plugin, plugin.xml file if I use,
objectClass="org.eclipse.core.resources.IResource", this action is
visible and enabled in context menu of internal editors only.
If objectClass="org.eclipse.ui.IEditorInput" is used, the action is
visible and enabled in context menu of both internal and external editors.
Following is the code snipppet of plugin.xml for my plug-in.

<objectContribution
adaptable="true"
id="my.plugin.objectContributionAction1"
objectClass="org.eclipse.core.runtime.IResource">
<action
class="my.plugin.internal.Action1"
enablesFor="1"
icon="icons/obj/image.png"
id="my.plugin.Action1"
label="Action Label"
tooltip="Action Tooltip">
</action>
</objectContribution>

I am not able to find any hints on how to show the action in context
menu of external editors only.

Any suggestions would be of great help.

Thanks,
Sneha

You would probably need to use a more complex <enablement> clause, so
you can evaluate that it is <not> an IResource.

With core expression, you would use <not><adapt
type="...IResource/></not>. That's used with org.eclipse.ui.menus
menuContributions.
