[Moose-dev] Mondrian to Roassal: TreeMap

Hi all, With the recent release of Roassal I thought I try it out and see if I can port my TreeMapLayout from Mondrian to the new engine. First of all: I really like Roassal. I felt while it was similar to 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. There are two things which are missing (or I did not find them) to enable to draw a real TreeMap though: z-ordering and making edges invisible. Roassal seems to render the nodes in the order they are given to it, 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. And how would I go on about making edges invisible? Cheers, Dennis
