[Moose-dev] Re: Mondrian to Roassal: TreeMap

can port my TreeMapLayout from Mondrian to the new engine. That would be excellent. Mondrian it was easier to use and understand. I was able to throw away some boilerplate code in my layout, it is much cleaner now. Also, the porting did not took much time. Thanks. That is exactly the goal of Roassal. enable to draw a real TreeMap though: z-ordering and making edges invisible. Making edge invisible is easy. Just try: -=-=-=-=-=-=-=-=-=-=-=-= | view edges | view := ROMondrianViewBuilder new. view nodes: Collection withAllSubclasses. ( view edgesFrom: #superclass) do: [ :edge | edge - ROEdge ]. view treeLayout. view open -=-=-=-=-=-=-=-=-=-=-=-= You need to update to the last version. I also introduced an example and tests about making element invisible. The Mondrian builder assigns a shape per default. You can always remove it using Roassal facilities.

meaning the first node will be "under" all the others with the last one on top. Is there a way to alter this? In Mondrian every shape had a zOrder index. This is something that I do not have a solution yet. What exactly do you need? How do you want to specific the node ordering? The node ordering can certainly be changed, but I would like to do it without introducing a zOrder. The reason is that on some point, I would like to have quadtrees, and the zOrdering may hamper it.
