to the change when I add a connection between nodes.
It looks strange, I think it should do the listening of connections, but it
didn't in my case, I want to know if there is any other way to listen for
the change when I add a connection between nodes?

Connecting 2 nodes will result in changing at least three EObjects :
1 - The Source View, this will result in firing an add event on the
SourceEdges EStructual feature of this view
2- The target View, this will result in firing an add event on the
TargetEdges EStructual feature of this view
3- The diagram that contain this edge, this will fire an add event on
the persistedChildren or the transientChildren EStructual feature of
this Diagram
so, you can catch the event you like in the appropriate edit part.

yes, I agree with you. But I don't want to change the code which is
generated by gmf, regarding that gmf will be updated in future.
First try, I new AdapterFactoryContentProvider() and overwrite its
notifyChanged(Notification notification) method and listen to the changes,
unfortunately, it doesn't work in my case.
How can I listen to this change without change the code generated by gmf?
thank you.
