Hi Julian,

I am not sure what you mean.  Can you describe in more detail what you me=
an by
"Lazy Tree" or "Lazy Explorer" or "load only what you need".  Load what a=
nd
not load what else?  What do you want to avoid loading?

Ok, I think I understand.  Is this what you mean?  For instance, let's us=
e =

http://dynapi.sourceforge.net/releases/dynapix/examples/dynapi.gui.explor=
er.html
for reference.

I hit the page, and I see it takes a very long time to load, as it loads
everything.  On the other hand, when it runs, it runs very quick.

Say we load only the top level, then load only if required by expanding a=
 tab.
 The downside is that the application might seem slow.

So something aynchronous might be desireable.  Perhaps load the top level=
, and
display it, then continue to walk the tree breadth-first and load the dat=
a for
sub levels while waiting, and stop to handle any user actions?  That seem=
s
very complicated to me, but might be the right way to handle it for the u=
ser
experience.

Any comments or ideas how to implement?  It's a feature request, so I'll =
copy
the results of the discussion there and refer to this thread.

[Doug M. <do...@cr...>]

I built a tree much like this (Not DynAPI) for a commercial site.
They had 800+ items to load in their tree and this took WAY too long.
Assuming that any given branch does not exceed a couple dozen nodes then
rendering a branch on demand should not be too demanding.

My Plan:
If you click on a node load only the childs of it not more of the tree
so a async one, i think
