Hello Matthias,
If you are trying to perform the same action as F5 does then you can have
a look on generated ???DiagramUpdateCommand.

Can somebody give me an code example how to use DiagramUpdateCommand?

Hello,
I'm trying that as well at the minute and I got stuck.
Looks like MyPackage.eINSTANCE.getTopic_Subtopics().equals(feature)
doesn't work for me because the methode getTopic_Subtopics() doesn't
exist. Does anybody know, what I'm doing work here?
And another question. Does this approach provide me with full history
support? As refreshing the diagram the way I do it currently, leads to
exceptions when using the undo facility.
Cheers,
Matthias

You'll need to use a method from your model, that which returns the feature
you're interested in. The method getTopic_Subtopics() is from the mindmap
domain model.
I've never noticed any problems with undo following a diagram update.

Rich

Hello,
Thanks for your answer Rich. I do understand the code better now.
But my problem is slightly different to Martin's. I've created a plug-in
which adds an action to the right-click menu of my diagram shapes. This
action changes it's fields and after that the shape needs to be changed
if a certain field has a certain value.
Everything works fine. The fields get updated and the shape changes it's
style upon the specified constraint. But (besides the known bug, that
the shape jumps to a position near the middle of the diagram) there are
still history issues.
Let's say I use the undo facility. It seams that the refresh activity
doesn't get stored. That means that the shape style doesn't change back
when I roll back.
Here is what the action contains to refresh the diagram:
CanonicalEditPolicy canonicalEditPolicy = (CanonicalEditPolicy)
mySelectedViewElement.getParent().getEditPolicy(EditPolicyRo les.CANONICAL_ROLE);
canonicalEditPolicy.refresh();
While mySelectedViewElement stores the current shape's EditPart.
Any hints are welcome.
Thanks,
Matthias

Hello again,
I managed to implement your example, Rich.
But I really would like to add the refresh behaviour via a plug-in. I
assume, I'm not able to override this method "protected void
handleNotificationEvent(Notification notification)" via an extension
point - right? :)
The point is, that it doesn't effect only one EditPart but a big number
of ShapeNodeEditParts and I really would like xxx.diagram plug-in to
leave it as it is.
So can you give me a hint how to do that?
Cheers,
Matthias

Hello,
Well, you could customize the code generation to incorporate the behavior
you'd like. Or, if you mean you'd like to keep the generated .diagram
plug-in as is, you can create another plug-in, contribute a custom
EditPartProvider, and then substitute/extend the existing EditPart with the
one containing the logic below (or that you'd like).
Best,
Rich

Hi Rich,
Yes!
I think adding the custom EditPartProvider using a separate plug-in is
exactly what I'm aiming for.
Can you give me more informations where and how to start? Which
extension points need to be used? Is there some documentation available
out there?
Thanks a lot.

You can start here:
http://help.eclipse.org/help32/topic/org.eclipse.gmf.doc/how to/diagram/howto
..html#overrideConnectionLook
I have an example in the book as well that I can share, if this doesn't do
the trick.
Best,
Rich

Hi Rich,
This is definitely a step in the right direction. Thanks.
My only problem is, that I have to override the method
createConnectionFigure() and I don't really want to do that. I'm only
aiming for the method handleNotificationEvent().
Can I still do it that way or do I have to aim for a different approach.
Cheers,
Matthias
