I create a process diagrm such as process.process_diagram in my picture,
when I doulbe click on the element 'a', it will programmatically open a
subdiagram called a.diagrm.process_diagram with an element called 'data'.

Now, I want to disable the "delete from model" function for the element
'data' I created in subdiagram, what do I need to do ?

Thanks,
dzh

Hi dzh,

You could return an unexecutable command from your
xxxSemanticEditPolicy#getDestroyElementCommand, or from your
xxxEditHelper#getDestroyElementCommand, to disable the "Delete from
Model" menu item for that kind of element.

Regards,
Linda

Hello dzh,

You can take a look on plugin.xml generated for Ecore diagram editor - it
removes "deleteFromDiagramAction" for some elements. I think you can remove
"deleteFromModelAction" in a same way.

<contributionItemProvider class=" org.eclipse.gmf.runtime.diagram.ui.providers.DiagramContribu tionItemProvider "
checkPluginLoaded="false">
<Priority name="Low"/>
<popupContribution class=" org.eclipse.gmf.runtime.diagram.ui.providers.DiagramContextM enuProvider ">
<popupStructuredContributionCriteria objectClass="org.eclipse.gmf.ecore.edit.parts.EAttributeEditPart "/>
<popupPredefinedItem id="deleteFromDiagramAction" remove="true"/>
</popupContribution>
.......
