Changing style of a non selected label.

[Stefan]

Hi,
I'm doing a project on visualizing in what order different search
algorithms traverse the nodes a tree. Since Spacetree is by far the
best (maybe even the only) library I could find for Javascript that
can draw trees, even with cool effects, I will be using this.
(complements on the library). However, after struggling for a long
time, I'm posting here for some basic questions about how to do
certain things.

I wrote a function that converts my own tree datastructure to JSON
format and I got it to load and display by the SpaceTree library. I
also managed to display all nodes without having parts of it collapsed
and i found out how to focus on a specific node. There are some things
I couldn't get to work though:

- The search algorithms visit the nodes in the tree in a certain
order. Whenever a node is visited I want to mark it by giving it, for
example, a red border, or any style for that matter. What is the
proper way to do this? I'm having a bit of difficulty to determine
which functions named in the manual do what exactly. I didn't manage
to figure it out by looking at the style morphing example. Could you
tell me which functions to use for this?

- Also is there a way to change the data in the nodes, after the JSON
tree has been loaded? I want to put some html in the data field, and
show that in the label, but I'm not sure how I can change this after
the tree has been loaded.

Hope anyone can help me out :)

Thanks in advance.
