Hi all,
For my solution I'm using two different node mappings with two different
figures. This works well enough (I have to refresh using F5, still) but
I'd like to change the visuals by double clicking on the shape. I know I
need to use an OpenEditPolicy, but I'm unsure how to accomplish this,
code-wise. I could use a pointer or two :)

You could take a look at the default generated OpenEditPolicy that is used
for diagram partitioning (or, take a look at the one in the Ecore diagram
example). The important method is below, though you'll want to replace
OpenDiagramCommand with one that suits your needs.
What I don't think I follow is why you'd want to have a double-click change
an EditPart. Do you simply want to change the figure? If so, you should
probably take a look at the UML2 Tools approach to changing figures (e.g.
Displaying a circle or rectangle for an interface). They use a context menu
item. Note that they are able to maintain the position of the figure by
setting the original's in the request when creating the new view.
Best,
Rich
public class OpenDiagramEditPolicy extends OpenEditPolicy {
protected Command getOpenCommand(Request request) {
EditPart targetEditPart = getTargetEditPart(request);
if (false == targetEditPart.getModel() instanceof View) {
return null;
}
View view = (View) targetEditPart.getModel();
Style link =
view.getStyle(NotationPackage.eINSTANCE.getHintedDiagramLink Style());
if (false == link instanceof HintedDiagramLinkStyle) {
return null;
}
return new ICommandProxy(new
OpenDiagramCommand((HintedDiagramLinkStyle) link));
}
private static class OpenDiagramCommand extends AbstractTransactionalCommand
{
....
}
}

What I want to do is basically 'expand' and 'collapse' the EditPart. Not
just change the figure, but also change the way features are displayed,
and which features are displayed. So basically I want to keep my
original view, or at least have an exact copy.
Basically, with the different top node reference I get what I want. Only
think is I want to do this programmatically, instead of changing the
property in the sheet and refreshing the diagram manually..
Let's see if I can find OpenDiagramEditPolicy first.. I don't think it's
generated in my particular project though..

Well, it won't be generated if you've not set the Related Diagrams property
on a node mapping.
I suppose a compartment didn't suit your needs for expand/collapse?

Okay.. well diagram partitioning wasn't really on my to-do list but I
can experiment a bit ofcourse..
I've considered using a compartment, but then.. the figure should still
resize and/or change.

I had a very similar problem and asked here before two days in the
thread "Refresh when constraint value has changed". The only difference
in my problem was, that I wanted to refresh the figure, when a property
of the domain model changes instead of double click. However, the main
trick to solve it was to call refresh() on the ???CanonicalEditPoliy.
Actually the answer from Boris Blajer in
http://dev.eclipse.org/newslists/news.eclipse.modeling.gmf/m sg12307.html
helped me to solve it.
I implemented a custom IEditPolicyProvider to extend the extension point
org.eclipse.gmf.runtime.diagram.ui.editpolicyProviders. That policy
provider registered a custom ???CanonicalEditPolicy for the diagram
editPart and the role EditPolicyRoles.CANONICAL_ROLE. That's my custom
edit policy, you can see, that it just calls refresh of the generated
CanonicalEditPolicy, that's all:
public class CustomWorkflowCanonicalEditPolicy extends
WorkflowCanonicalEditPolicy {
private ResourceSetListenerImpl changeListener;
@Override
public void activate() {
super.activate();
TransactionalEditingDomain editingDomain = ((IGraphicalEditPart)
getHost()).getEditingDomain();
changeListener = new ResourceSetListenerImpl() {
@Override
public void resourceSetChanged(ResourceSetChangeEvent event) {
super.resourceSetChanged(event);
refresh();
}
};
editingDomain.addResourceSetListener(changeListener);
}
@Override
public void deactivate() {
TransactionalEditingDomain editingDomain = ((IGraphicalEditPart)
getHost()).getEditingDomain();
editingDomain.removeResourceSetListener(changeListener);
super.deactivate();
}
}
Regards,
tobi

I think I can use at least some of this... thanks!

I think I should be able to solve it like this:
- Set the property that the top node reference constraint acts on
- refresh the diagram
These things should be done from an overridden OpenEditPolicy, since
I want to do them on double clicking on the element.
Any light anyone could shed on this would be appreciated..
