Roassal2: how to add a node to a layout post-factum?

Hola,

Say I have a layout:

elements := <a collection of elements>
layout := RTForceBasedLayout new applyOn: elements; yourself

and then later I instantiate another element newElement, how can I tell the layout to take this one into account as well? If I add it to the collection of elements, nothing happens, and if I add it to the collection of elements contained in the layout I get the red error morph. :-(

You probably have to reapply the layout on the new collection.

It would be cool to get an animation that can handle such an addition.

In reply to this post by jfabry

Simply do “layout on: <your collection of elements>”

Re: Roassal2: how to add a node to a layout post-factum?

Yes, that works, thanks! But …
- there is no force being applied in the layout on any elements at all
- as Doru said, there is no animation when it is added even though I have a RTSpringLayoutStepping animation on the view :-(
