[news.eclipse.tools.gef] Re: how to Identify the model present on the ed

["Steven Shaw" <steveshaw@xxxxxxxxxx>]

In the context of GEF the targetting mechanism is handled behind the scenes.
You can handle these targetting scenarios by installing appropriate
EditPolicies on your EditPart.  The editpolicies installed would handle
requests for add (REQ_ADD), orphan (REQ_ORPHAN).  Orphan requests means the
receiver is being moved from it's current parent.  @see ComponentEditPolicy.

If your working in the context of Draw2d, then there are api's on the
containing Figure you could use Figure#findFigureAt(...)
