Hello,
I had a question about the highlight of connected edges when selecting the node. If I select a node, so I would like to highlight (selected) all edges that are connected to the node.
On the attached picture you can see that when you select a node TST001_U002 are selected and connected edges. Ideally, still change the color of edges connected (but not necessary).
Can this be done?
Thanks so much for any advice.
Martin

Hello,
That is a nice idea, especially on big diagrams. The highlighting is
managed by
org.eclipse.sirius.diagram.ui.graphical.edit.policies.SiriusGraphicalNodeEditPolicy.addHighlight().
You will have to provide your own EditPart[1] in order to install your
own EditPolicy overriding ours. In createDefaultEditPolicies, you should
have something like
self.installEditPolicy(EditPolicy.GRAPHICAL_NODE_ROLE, new
SuperCoolHighligthingSiriusGraphicalNodeEditPolicy());
Note that in your EditPolicy you will have to override the
showTargetConnectionFeedback method. The method addHighlight is private
but you will have your own implementation anyway.
Regards,
Steve

Hi,
I think that the policy proposed by Steve is not the only one that can
be used. In Sirius, we already done something smiliar. When you select
an edge, the edge label is "highlighted" (and conversely). This is done
in [1] and [2].
This is another entry point.
[1]
org.eclipse.sirius.diagram.ui.graphical.edit.policies.AbstractEdgeSelectionFeedbackEditPolicy.createSelectionHandles()
[2]
org.eclipse.sirius.diagram.ui.graphical.edit.policies.DEdgeSelectionFeedbackEditPolicy.createSelectionHandles()
Regards,
Laurent
