Moving Nodes by dragging a connection [message #229322]

Hello together,

I asked this question in the gmf newsgroup already but i think the gef
newsgroup is a better place:

Id like to move two nodes in a diagram by dragging the connection
between these nodes around (I need this for a sequencechart where
messages between lifelines are connections).

Does anybody have an idea for a general approach to this? E.g. what
editpolicies i'll need or something?

best regards,
David

I have never done this but here is a suggestion:

In your connection's editpolicies, you can create a command to move the
source and target editparts (using the same drag delta obtained from the
connection). You probably don't have to worry about the connection
because it should follow the source and target figures automatically.
