How to refresh model source/target connection “children” of GEF NodeEditParts

Posted on 20 September 2012 by Stephan Druskat — 2 Comments ↓

I am currently developing a GEF-based editor for an EMF-based model with the help of the GEF Book, and vainolo’s incredibly helpful blog posts.

I had implemented connection creation, following vainolo’s post about connections, but in my editor, the added connection figures never showed up, although the respective model objects had been instantiated (I’ve checked!). It was only after I had saved the graph, and re-opened the editor that the connection figures became visible. The respective code bits looked like this: Read more ›

For people who like to read books rather than websites. It is as up-to-date as can be, and is a very good and comprehensive introduction to the Eclipse RCP. Can be read back-to-back, or used as a reference. I have used this almost exclusively in my “early days” of programming with the Eclipse RCP. Read more ›
