Disable "Delete From Diagram" [message #219787] Tue, 24 February 2009 07:08 Go to next message

Hello all,

my Diagram Editor is synchronised to a model. The "Delete From Diagram"
Action is disabled for all elements... except for one.
I don't think i made something different on creating that element.

The only difference i see, is that the element, where the "Delete From
Diagram" Action is available, is a Association that can have an other
association as source or target.

However, is there a way to manually disable the "Delete From Diagram"
Action?

I was looking around in the corresponding Edit-Policy class, but
couldn't find a command that gets created from that class, that is
responsible for the action.

Thx in advance, Arne

Hi Arne,

go to the plugin.xml file, and then all you have to do is :

<popupPredefinedItem id="deleteFromDiagramAction" remove="true"/>

under the extension point :

<extension
point=" org.eclipse.gmf.runtime.common.ui.services.action.contributi onItemProviders ">


This is what i have for an element of my model : ActivyEditPart.


<extension
point=" org.eclipse.gmf.runtime.common.ui.services.action.contributi onItemProviders ">
<?gmfgen generated="false"?>
<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=" com.isoco.iwf.designer.bpmn.diagram.edit.parts.ActivityEditP art "/
>
<popupPredefinedItem id="addNoteLinkAction" remove="true"/>
<popupPredefinedItem id="fileMenu" remove="true"/>
<popupPredefinedItem id="cut" path="/editMenu/copyGroup"
remove="true"/>
<popupPredefinedItem id="copy" path="/editMenu/
copyGroup" remove="true"/>
<popupPredefinedItem id="paste" path="/editMenu/
copyGroup" remove="true"/>
<popupPredefinedItem id="deleteFromDiagramAction"
remove="true"/>
<popupPredefinedItem id="deleteFromModelAction"
remove="false"/>
<popupPredefinedItem id="formatMenu" remove="true"/>
<popupPredefinedItem id="filtersMenu" remove="true"/>
<popupPredefinedItem id="showPropertiesViewAction"
remove="true"/>
<popupPredefinedItem id="properties" remove="true"/>
</popupContribution>
hope it helps.

Hi!

Yes it really helped a lot, thank you!

It is a little emberrassing, since I already worked with that extension
point and still was trying to "grey the actions out" instead of using
the extension point to remove the action completely. I was really blind
there.

Anyway, you really helped me there :)

Arne

Hey Markitus!

Does this only remove the context menu entry or really disable deleting
at all? I have the problem that the "Backspace" key is also mapped to
"delete from diagram" for single EditParts. Will this binding be removed
then, too?

BTW: Did not really get this to work. Using this extension point only
did *enable* the "delete from model" but not yet disable the "delete
from diagram". In my case I have a feature label attached to a
connection edit part that can be removed from the diagram.

Cheers,
Hauke
