Hi,

I want to execute a set of code when I select the source on edge creation. I am not able to find where I need to add the code.

I tried adding in

- "Connection start Precondition" which will execute when we mouse over on the source node not on the selection of source node. But I want on selection of source node!!.

Can anyone help where I need to add the expression which will execute on selection of source node, before connecting the target node.

Hi,

There is no easy way in Sirius to provide a service that will be executed once the edge source has been selected.
You have different possibilities. You can provide your own EditPart and EditPolicy that will return a specific command for the connection start: org.eclipse.gmf.runtime.diagram.ui.editpolicies.GraphicalNodeEditPolicy.getCommand(Request). That requires some GMF/GEF knowledges.
You can also provide a SelectionListener through this API : site.getWorkbenchWindow().getSelectionService().addSelection Listener(myListener);
