Moving Nodes by dragging a connection [message #92454]

Hello again,

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 code to change?

best regards,
David

I tried this in GEF, but I don't know if it's possible in GMF, even if I
think so. You should try to:
- disable bendpoints for the connection
- use getCreateBendpointCommand to return you own command in order to apply
the move-delta (I find the gap between the old position and the request
location) of the request to your ends
AM

protected Command getCreateBendpointCommand(BendpointRequest request) {

return new MessageMoveCommandSequence((Message)model, getHost());

}

Hi,

does anybody have a solution to that problem in the meantime. I have the
exact same problem at the moment.

Cheers,
Daniel
