Visualize connections when Source and Target(EditParts) are the same. [message #162065]

Hello everybody,

I want to visualize a state diagram with gef. When nodes are states and
connections are (state-)transitions there is exists also
"self"-Transitions, a connection where source a target node is the same.
My standard visualization (polyLine with Arrow-Decoration) paints
only an arrow at the bottom of the node-figure. But i want to visualize
it like this:

node<--
| |
| |
-------
my hope is that someone has already coded somethign similar like this
above... Any suggestions?

Alex

You could add some bendpoints to the connection when you create it. The
EDiagram example in the repository does this. It's not a very elegant
solution though, because then when you move the node, the bendpoints stay at
their original location.

You need to identify this special case in your connection router, and create
the loopback points.
