Label for Connection [message #200827]

I was wondering what the proper way is to add a user-moveable label to a
connection.
Can I just return the label as a model child of the connection? And does it
make sense to use a ConnectionEndPointLocator to provide a default location
for the label?

please check the QVT diagrammer code, ConnTextMovePolicy.java at http://qvtp.org/downloads/qvtp-eclipse/
You will have to download the sources there.

This looks nearly like my code, and I have changed my code slightly to make
it the same.
But still my connection label does not get drawn. I put breakpoints into
Label.paintFigure(Graphics) and ConnectionEndpointLocator.relocate(IFigure),
but they are not reached. How come those methods are not executed?

Hope your Connection-Editpart is returning the model-children as those Connection-Child model objects (for which Label is the created figure).

Thanks

Oh yes, it does that. Also createFigure() and refreshVisuals() are called on
the EditParts for the labels, but it never gets to paintFigure() on the
Label (which is the relevant Figure).
