Hi,

I'm interested in state information about the progress of creating a
connection.
The states I'm interested in are
- not attached
- attached to source
- attached to target

The first state is the initial one. It is entered again if escape is
pressed or after having clicked on an invalid target.

The second state is assumed after clicking on a valid anchor.
Then a feedback figure for the connection to be created is drawn.

The third state is entered when a valid target anchor was clicked.
This is easy to determine since then
org.eclipse.graphiti.func.ICreateConnection.create(ICreateCo nnectionContext)
is called.

I did not find an easy way to find out about the first and third state
without digging into GEF...

Can anyone give me a hint?

Thanks,
Henrik
