Hi folks,

I'm pondering about how to change the z-order of a connection in a GEF-based diagram. Currently the ManhattanConnectionRouter is in charge for routing my connections. If there are a couple connections close together these connections were routed in the same fashion. As a result the connections overlap at some point and it is hard to figure out where is the origin and the destination of a connection.
To fix this I want to set a connection to the top level of the z-order when the user selects it and highlight it (highlighting is already done). I know that GEF defines the z-order about the children order of an EditPart . But I don't know which Part defines the order of connections. If i call getParent() within my ConnectionEditPart (extends AbstractConnectionEditPart) I will get a reference to ScaleableRootEditPart, but this one doesn't have any child connections.

I would be very glad if someone can give me a short sketch how to change the z-order of connections. I hope this is possible.

Thanks a lot in advance!
Kind Regards,
René

René,

Did you ever figure this out? I am trying to do exactly the same thing with our connections.

Thanks,
Erik

So I was able to get this working by changing the order the connection appears within the list of view in the connection layer. The top element is the last element in the list.
