Dear all,
I have created a plugin diagram, with which I can create simple graphs.
I would like to do navigation for nodes element via a popup menu.
For instance, for a node Node1, an access to a popupMenu allows me to
navigate in this node. That is to say, the node contains others nodes
inside, and I want to visualize only the nodes contained inside the node
Node1 in another view, by replacing the view of Node1.
I created a new menu on the node, and on "run(IAction action)" of the
Action class, I tried to create a new view and replace the old one, but I
didn't get what I want to do.
Does anybody know how to do that simply?
Best regards, and thanks for any hint.
Lima.

Hi exquisitus,
Take a look at the generated OpenDiagramCommand. It creates a new
diagram instance and associates it with the same underlying model
element that is associated with the notational element the edit policy
is registered for (Actually, this happens only the first time the
diagram for this element is opened, the resulting diagram is reused
afterwards). Thus, instead of opening a diagram for a compartment, it
actually opens a diagram for a diagram (whose underlying element is the
same as the one of the compartment), which is of course a valid operation.
Best regards,
Boris

Hi Lima,
Yes, it is correct. Diagram can only be opened for an instance of
org.eclipse.gmf.runtime.notation.Diagram. However, if the new diagram
displays exactly the same elements (and uses the same editing domain as
the original one so that changes to the underlying model that are made
in one are immediately picked up in the other), why would one care that
it is a different instance?
Best regards,
Boris

You're right, Boris. The new diagram should contain the same elements, so
it 's quite not interesting. But I wouldn't like to display the top level.
It is in fact a compartment navigation, without displaying the father
compartment. For example, if two components B and C are linked and are
inside a compartment A, I would like to have in a new editor only B and C
with their links.
Thanks for you help.
Regards,
Lima.
