Extending the action of making a connection [message #551888]

Hi everyone,

I would like to realize such a feature in my GMF editor:

When I make a connection from a source node to a target node, I would like to automatically copy an attribute of the source node to the target node.

I think that this could be done by some event listener, right? Or is there other better solutions?

For GMF event listener, where should I start? I checked some threads already, but still not clear enough.

Thanks a lot.

Yu

You could do one of the following:

- modify the MyConnectionCreateCommand#execute() method

- implement (override) the MyConnectionEditHelper#getCreateCommand(CreationRequest) (see method in super class ) and provide a command for setting your attribute.
