Find-as-you-type in a Tree control

[Evan_K]

I'm a bit new to Flex (but not to Flash or ActionScript), and I'm building an
app that displays a tree control to the user. This tree corresponds to a
rather immense directory structure, and I'd like to allow users that are
looking for a specific path to just click the tree, type in the path (ie:
'home/evan/htdocs/scripts') and have it expand the tree to, and select, the
appropriate tree node.

My issue is, I have no clue how to even begin doing this. I know I could
probably trap keyboard events, but i have no idea how to efficiently search
through a tree instance. Has anyone ever done this before?

It is pretty easy to find a node based on some unique id in the item and expand
the parent path above it. I have a simple example of that on [url]www.cflex.net[/url].

But it sounds like you want to navigate by path. Depending that could be a
bit of a challenge, but I don't think unreasonable. Some functional decisions
to make, such as do you automatically fill in the filter box if a child node
uniquely matches the currently entered letters.

Though in truth, one of the benefits of a tree is graphical navigation. Id
rather navigate normally through the tree with three clicks and maybe a scroll
or two than type in 'home/evan/htdocs/scripts'
