Render-Position of TableVisualItem (z-Index)

  • I have a custom TreeLayout (extending prefuse.action.layout.graph.TreeLayout) in which it is possible and necessary that some edges (prefuse.visual.tuple.TableEdgeItem) overlap each other.
    In such a case I want to control which edge is rendered in the foreground and which in the background.
    I was expecting something similar to the z-index in html but couldn't find anything in prefuse.

    How can I do that? How can I decide which Visualitem is rendered in the foreground?
    Any help is highly appreciated! thanks!
