Dynamic Tree Example 2007-09-06 - By Manu Mahajan
Back
Hi Session
I am really sorry I couldn't work on the examples as I had promised. I have
just been extremely busy over the last few weeks. I want to contribute and
it's the first thing I will do when I get some time.
I have already answered your question on saving and restoring the state of a
tree.
For adding icons I am sure it can be done in the latest version dojo but I
will have to explore this a bit. I am not sure if it can be done with the
version of dojo bundled with struts.
There is an example of loading a tree dynamically in the showcase but I
think what you are looking for is to load a partial tree and then load the
rest of the nodes based on what node is expanded. I haven't found any such
examples.
Interestingly we have a similar requirement in one of our projects and after
reading your mails in the morning I asked my boss to let me work on that :)
So I will be working on this for the next few days and I will update you if
I make any progress.
Manu

Hi Manu,
You seem to have had lots of experience with s:tree; would you please help
me answer the following questions (with example code if you have them):
- how do you go about expanding the tree to the node level it was at before
a refresh?
- can you add icons (not changing the plus/minus ones) to the tree nodes
individually, to differentiate between the types?
- are there examples of lazy-loading data in a tree?
Thanks,
Session
