Hi there,
I wrote a RCP with a GEF-Editor and Property-View.
The Prop-View shows the name, the coorinates and size of the drawn
figures as key-value pairs.
When I move a figure the Prop-View updates itself.
When I edit the name field in the Prop-View the GEF-Editor does not
update. I have to click on the editor to refresh the actual editor "view".
I use a Model generated by EMF, so I can't code in directly in the
Model. I thought I have to code sth like listeners there. I'm clueless
now. Do you have some hints? Shall I post classes here?
As I began with GEF I read that I have to edit the Model (objects) and
GEF recognizes that and updates the rest by itself...hmm as
described..it does not.
Greetings
Juergen

In simple words: I edit a string field in the prop-view and make a click
in the gef-editor --> the string text gets refreshed in a label in a
figure. But only if I click on the editor or add sth to the editor. When
I edit the string in prop-view and push enter, the propview has the new
string but the editor the old string.
Again: If a paint or paintFigure method is called, every is fine, but
this doesnt get invoked. In other words: a) I think the editor is not
connected properly to the Model, so the editor doesnt get notified. b)
or I have to call a refreshVisual(), but I dont really know.
I made a short video (wmv or avi):
http://rapidshare.com/files/218943119/gefmodelrefresh.wmv.ht ml
http://rapidshare.com/files/218942488/gefmodelrefresh.avi.ht ml
Can you explain, how I make the editor listen to model changes?
I put the editor code below this text, maybe it helps. Maybe it has sth
to do with the getAdapter method, but I dont know.

I really wonder now, why this works. Maybe because its a standard
Property View. I just implement the standard class.
public class MyPropSource implements IPropertySource {...}
Do you have an example on: how to connect a selfmade RCP View to the
gef/emf model?

How do I do that? f.e. I open the Node.class and set a breakpoint there
and then run debug mode, correct?! for what do I have to look?

thx, I see.
