Hello everybody.
At first, thanks to Joel. My mistake.

After adding updateFace() to the constructor a part of the problem still
remains. When reopening the diagram file, labels in the node (that are
affected by updateFace, too) have their original color.
To me, it seems that WrappingLabel.setForegroundColor has no effect, if
it is called from a constructor of a Figure. Sounds pretty strange, I know.
Do you guys have any hints how to solve that?
Regards,
Mark

Where are you calling what? Are you trying to update child figures? In the GMF tutorial, the updateFace() is called
before createContents() where your WrappingLabels will be created. You may want to try calling the uodateFace() after
the createContents() -- I don't know why they propose this order.
Or try modifying the createContents() method.

Hi all.
It's working now. There were subsequent calls to setForegroundColor
after the ones in my code. I suggest the following steps for
"making figures sensitive to attributes of semantic elements":
- React on direct changes of semantic element (in all cases):
override handleNotificationEvent (as described in the wiki)
- Initialization after reopening the diagram file:
- Nodes: add init code to end of constructor
(as described in the wiki)
- Labels: add init code to the end of refreshVisuals
- Edges: add new method refreshVisuals (overrides inherited one);
add call to refreshVisuals of the superclass;
add init code
If you think this is absolutely wrong, please tell me/us.
Cheers,
Mark
