Hello everyone,
I need some help with the tree node labels in ECP. I want to change these labels in a more generic way. By changing I mean that instead of the <model element name + name/type/other attribute> label, I want to have the <model element name + a computation of different values> label (for example, a computation could be the name of an attribute + the value of another attribute).
I've found one approach in the Adapt Label section from the eclipsesource.com, How To Customize the EMF Client Platform (sorry, cannot add an external link yet), but it is not what I am looking for. I do not want to modify the getText() method, since there are many elements with different kind of computations. I'm searching for a generic solution, that can be later used by another user/developer for many other elements, without any code changes. Is there any way to provide this behavior?
Any suggestions will be appreciated,
Roxana

Hi,
can the behavior be implemented in a generic way, meaning is the
calculation the same for all elements?
Best regards
Jonas

Hi,
ECP uses the default label provider, so any solution, which works with
them in general should work with ECP, too.
Best regards
