I declared a command and a handler for it. Now I want to enable the
command in popups. The point is that the command should be enabled when
right-clicking a folder (for example in the package explorer) and only
if the folder contains files of a certain type (for example a EMF
resource). Is it possible to declare this issue in the plugin.xml?
best regards,
Gilbert

Hi Prakash,
thanks for the link. But what is described there is only how to
determine the explicit elements of the selection. That can be achieved
with that:
<activeWhen>
<with variable="selection">
<iterate operator="or">
<instanceof value="org.eclipse.core.resources.IFolder"/>
</iterate>
</with>
</activeWhen>
But what I need in addition to that is something like the following:
<enabledWhen>
<with variable="children">
<iterate operator="or">
<instanceof
value="org.eclipse.emf.ecore.resource.Resource"/>
</iterate>
</with>
</enabledWhen>
The point is that I want to check the children of the selected element.
Can this be achieved anyhow?
