Hi,

I managed to achieve that by contributing a custom EditPolicy using the EditPolicyService. The idea is that an EditPolicy provides (additional) behavior to an EditPart. Using the service you can declare multiple EditPolicies to be installed on existing EditParts.

For more information, look at the GMF help:
Eclipse -> Help -> GMF Developer Guide -> How To -> Runtime -> How To Guide For Diagram Layer Components. There is a subsection How to change the color of a shape dynamically, which probably is similar as what you would like to achieve.

Good luck!

Hi,

you can use pins in gmfgraph and visual effect mappings in gmfmap to achieve this.
