I was wondering how can I capture the request that is called when i drag and drop an instance of a editpart(node) in the editor and in wich part of the code it is because i need to move some elements in concordance with the node (links). is there any interfaz to implement or any listener to attach and manage?

Regards

Fernando

Hello,
Take a look at the editpart corresponding to your element.
See the getCommand(Request ..) method.
you could try to handle a notification also. Take a look at the mehod (in the same edit part calss):
handleNotificationEvent(Notification event).

You could also override, in the edit helper class corresponding to your edit part, the method:

protected ICommand getMoveCommand(MoveRequest req) {
		return new MoveElementsCommand(req);
	}

and return, there, an additional command to execute.

Cheers,
Emil.
