Hello!
ACK!!! I am attempting to "AUTO" populate a tree control....
Right now I am just focusing on dynamically creating the data structure
(a list of lists) that will later be used to populate the tree control.
This is where I am stuck!
Based on some research I've done, I think I want my data structure to
be a series of lists within lists:
[ "node1", "node1a", "node1b", ["node1c", "node2", "node2a", "node2b",],
["node1d", ["node2c", "node3", "node3a"], "node2d"], "node1e"]]
-------------------------------------------------------------
The list above represents this tree structure:
Node1
Node1a
Node1b
Node1c
Node2
Node2a
Node2b
Node1d
Node2c
Node3
Node3a
Node2d
Node1e
-------------------------------------------------------------
All of my data will be variable and I collect all the node information
via SQL queries.
But now I have a series of lists:
["node1", "node1a", "node1b", "node1c", "node1d", "node1e"]
["node2", "node2a", "node2b", "node2c", "node2d"]
["node3", "node3a"]
If I execute my sql queries in a series of nested 'FOR' statements I
get the hierarchy for each node traversal (as shown below) - but not in
tree format. For example "1c" has many branches - so it is returned 3
times.
Node1
Node1a
Node1b
Node1c
Node2
Node1c
Node2a
Node1c
Node2b
Node1d
Node2c
Node3
Node1d
Node2c
Node3a
Node1d
Node2d

So - my questions:
Is there an existing method/class/library that already exists in python
to help me create the data structure I need for my tree structure?
If not, can someone give me some pointers on how to think about this
clearly?? I'm obviously missing some steps!! :-(
As an aside, I'm using wxpython for my GUI
Thanks!
Lauren
