Hi, I'm looking to draw a tree where the root is on the left and each child node is drawn to the right. It seems that the qtree package can't do this. Any one have any ideas? I've found this document, which seems like it might help, but it's a bit obtuse. ...

I've got multiple structures to maintain in my application. All link to the same records, and one of them could be considered the "master" in that it reflects actual relationships held in files on disk. The other structures are used to "call out" elements of the main design for purchase and work orders. I'm struggling to come up with ...
I have item renderers in an mx.controls.Tree that I need to refresh on demand. I have code in the updateDisplayList that fires for only some of the visible nodes no matter what I do. I've tried triggering a change that they should all be listening for; I have tried clearing and resetting the dataProvider and the itemRenderer properties....
Can we use ItemRenderers in 2nd and 3rd depth levels of a treecolumn in a tree mode of AdvancedDataGrid? I have been able to use ItemRenderer in the 3rd depth level of an AdvancedDataGrid. If I use ItemRenderer in both the 2nd and 3rd level, then it is rendered in the 2nd level but then that cell loses its tree mode i.e. it doesn’t ha...

This is a simple question from algorithms theory. The difference between them is that in one case you count number of nodes and in other number of edges on the shortest path between root and concrete node. Which is which? ...
I'm using the ancestry gem to help organise my app's tree structure in the database. It basically writes a childs ancestor information to a special column called 'ancestry'. The ancestry column for a particular child might look like '1/34/87' where the parent of this child is 87, and then 87's parent is 34 and 34's is 1. It seems possib...
Suppose I want to change the orange node in the following tree. So, the only other change I'll need to make is in the left pointer of the green node. The blue node will remain the same. Am I wrong somewhere? Because according to this article (that explains zippers), even the blue node needs to be changed. Similarly, in this picture...

I've done my SO and Google research, and haven't found anyone who has tackled this before, or at least, anyone who has written about it. My question is, given a "universal" tree of arbitrary height, with each node able to have an arbitrary number of branches, is there a way to uniquely (and efficiently) "fingerprint" arbitrary sub-trees...
We are currently working on a project where the main domain objects are content nodes and we are using an ACL-like system where each node in the hierarchy can contain rules that override or complement those on their parents. Everything is as well based on roles and actions, for example. Node 1 - {Deny All, Allow Role1 View} \- Node 2 - ...
