[Moose-dev] more rubberbanding & interactions on ROView

With the recent integration of RORubberBand, I have then gone to use it in my application. What arises is that while the implementation works well within a single script in ROExample, it is not so well when the creation of elements is more spread out in different parts of the code, since these different parts do not have access to the same instance of RORubberBand. So some further thoughts on rubberbanding for discussion... 1. Since the rubberband operation is between elements, perhaps this should not be stored inside individual ROElements but more globally in ROView. That is, perhaps ROView would have its own interactions. 2. Currently to avoid the MNUs due to the target filter condition processing edges and elements with nil or unsuitable model, in (RORubebrBand>>initializeElement:) I used (candidateTarget getInteraction: self ifPresent:) where it is the 'self' that ensures that source/target elements being compared are applicable to a particular RORubberband. It is that 'self' that is hard to distribute to elements that are created from different parts of the code. Perhaps this mechanism could be replaced by tagging RORubberBand defined in different elements with a common symbol eg #rubberband1 Or tag the elements associated with a particular rubberbanding are just tagged the same as the RORubberBand instance stored in the ROView. 3. Perhaps not bother with trying to ensure no exceptions occur in the execution of the target filter condition, and just mask them out. Rather than interrupting the program with a MNU, targets elements are simply excluded if the filter. What are your thoughts? cheers -ben
