Hi Alexey,
I don't know exactly what you want to achieve. But it sounds reasonable
to me, to create an IEditorActionDelegate. Add this action to
menu/toolbar with org.eclipse.ui.editorActions extension point (or
org.eclipse.ui.menus, if you like).

Hi Jan,
Thanks for the reply.
I've done a little investigation and it seems that GMF provides utility =
=
classes for this kind of extension. I added this code to plugin.xml and =
=
this added a button to the diagram's toolbar.
<extension id=3D"presentationContributionItemProvider" =
name=3D"%ext.presentationContributionItemProvider" =
point=3D" org.eclipse.gmf.runtime.common.ui.services.action.contributi onI=
temProviders">
<contributionItemProvider =
class=3D" org.spbu.pldoctoolkit.graph.diagram.infproduct.providers.Swi tch=
FIPContributionItemProvider" =
checkPluginLoaded=3D"false">
<Priority name=3D"Lowest">
</Priority>
<partContribution =
class=3D" org.eclipse.gmf.runtime.diagram.ui.parts.IDiagramWorkbenchPa rt "=
>
<partMenuGroup toolbarPath=3D"/" id=3D"toolbarTestGroup=
">
</partMenuGroup>
<partAction toolbarPath=3D"/toolbarTestGroup" =
id=3D"switchPresentationAction">
</partAction>
</partContribution>
</contributionItemProvider>
</extension>
What I need now is to wire the event from the button with an appearance =
=
change on the diagram.
My current idea is to find the current active DiagramEditor and call a =
method there, which will cause the diagram to re-paint itself. The =
canonical edit policy of the diagram will then update its data.
Is it a correct idea? :)
Thanks,
Alexey

Hi Alexey,
I assume, this action modifies the notational model? DiagramEditPart
listens to these changes. You should be able to catch corresponding
events inside #handleNotificationEvent and update diagram contents.
