There are two ways I can see what you can do. Actually the bindToModel implementation does not require a ITreeNode in
its parameter list, it takes any object together with a list of properties for getting to the child node, the parent and
evaluating the visibilty etc. If you have this methods already in your own structure you could use just that.
tree.bindToModel(treeRoot, MyStruct.class,"childred","parent","value",null,null) // the last two were enablement and
visibilty accessors that should work and create the desire effect shouldnt it ?
The second approach would be to create a TreeNode instance that wraps your own structure. You would then pass the
treeNode instance to bindToModel and subclass TreeNode to translate the methods into access to your own structure.
But I think the first approach should work for you much more better......
