ListAdapter was nice, thanks :)
But how do I express what is supposed to be Leaf nodes and what to be
Branch nodes?

Have you looked at org.apache.pivot.collections.adapter.ListAdapter? You might
be able to use this in conjunction with TreeViewBranchListener to construct
your tree nodes from your backing data structure on demand.

I have a tree-structure represented by a list of domain objects. Some of the domain
objects have a "children" property with a java.util.List of children. The
TreeView#setTreeData method takes a org.apache.pivot.collections.List, and I figured I
could do:
setTreeData(new ArrayList(myJavaUtilListList.toArray()));
This works so that I can see the first level of nodes, but I don't know how to
express branch nodes. Also, I would like to lazy load some of the nodes. I
think I need to use the TreeViewBranchListener somehow, but I can't find any
documentation or examples.
Do I need to wrap all my domain objects in TreeNodes or is there another way to
do this?
