What user interface are used in these pictures? (ui based node)

I am wondering which UI library is used in the images below (from CityEngine). Does anyone know other user interface libraries with similar capabilities (free floating, connected nodes with arbitrary user interface elements)? I think this may be part of the Eclipse / JFace / SWT toolkit.

In particular, from your second example, it really looks like Eclipse / JFace / SWT. To be sure how it gets this particular graphic view, you will need to see the source, but I assume that it can use GEF: http://eclipse.org/gef

While the surrounding user interface is implemented using Eclipse / JFace / SWT, the editor is not implemented using SWT or GEF, but with a custom non-public library based on OpenGL.

I found a stack trace where you can clearly see that the SWT / GEF / Draw2D code is not involved: http://forums.esri.com/CityEngine/forum-30031.html.txt

The rendering code lives in the org.corebounce.lib3d2 package.
