How to send change-events to interested views [message #538346]

Hello,
can anybody tell me what is the "correct way" to send change-events to interested views?
For example, suppose we have an RCP application with 3 views, all of which display the same domain model. If I now change the domain model in view number one, I would like to send a "ChangedEvent". The other views (view number two and three) can listen to this "ChangedEvent" so that they can refresh e.g. their JFace viewers in order to display the changed data.

Thank you very much for any hint.
Cheers,
Christoph

If you mean you select an entry in one of your views and the viewers in
the other 2 views need to update with new data, you probably want
http://www.eclipse.org/articles/Article-WorkbenchSelections/ article.html
.... posting a selection is how one view communicates with anyone that's
interested.

If you mean all of your viewers are displaying your model Person, and
the name attribute changes and they all need to show the new name ...
that only works if you model fires events when it changes. See the
databinding framework, which has support to hook up label providers with
IObservables. http://wiki.eclipse.org/JFace_Data_Binding
