Hello,
I am trying to make sense of the direct edit support that GEF offers. It
seems that at least some of the code that comes under the "DirectEdit"
label leads into a dead end road. For example, I was not able to find
any place where DirectEditAction is used, and I wonder what role a
DirectEditPolicy will play (except maybe answer true to understandsRequest).
Can someone point me to any kind of "canonical" exmaple/tutorial on the
workings of direct editing?
thanks,
Christian

Check out the logic example.

"Hello World"s interspersed...

DirectEditAction is if you want to trigger direct-editing from a menu or
something. The logic example doesn't do that. As for DirectEditPolicy, you
can look at its subclasses and their use in the examples to see what role it
plays. Your EditPart's performRequest() method will be called with
REQ_DIRECT_EDIT when direct-edit is triggered. See what the logic label
editpart is doing in this method to see how it triggers the direct edit.
All this has been mentioned on this newsgroup before, so just search for it
on here if you want more details.

thanks for the help. I have achieved my goals by using the logic example
as an initial template. In the end, my edit policy does nothing else but
provide a command (method getDirectEditCommand), which does the model
manipulation. The separation of responsibilities between these sometimes
seems a little artificial (to me)..
The main implementation focus in my case was in the DirectEditManager
and CellEditorLocator subclasses.
thanks again,
christian
