Just read about the new virtual tree widget !

Very cool, this helps with large datasets as the dom manipulation
is done on a 'need to' basis and not all at once ...

so I modified the sample in the demobrowser:

  http://tinyurl.com/5tgpezd

to add 100'000 nodes to the Network node

but no joy ... it takes my browser a minute todo that ...

If you open the log window in the playground you can see that
preparing the array with data took less than a second
while the marshalling of the data took about 50 seconds
and appending the data to the existing tree took another 12
seconds.

Doesn't this sort of defeate the purpose of the virtual tree/list.

Are there any thoughs on how to make this more dynamic ?

For the the branches of the tree it is pretty simple todo as they
can be populated upon opening this works even with the current
model, but inside a large branche I don't see any way to provide
content dynamically ...

cheers
