But there is no information on how I can traverse the tree - start with the root, get to the NextChild, get the label, delete a branch, programmatically expand or contract a branch, ... - all the standard things one would do with a tree...

My use of the tree control hasn't been much more sophisticated than the 
example. I did add a couple of extra method aliases to 
PythonCard\components\tree.py because the ones already there are only 
enough to support the example. So in __init__ I added

setExpanded = wx.TreeCtrl.Expand
clearTree = wx.TreeCtrl.DeleteAllItems

so that having built the tree from a dictionary I could open up all of 
the nodes at startup, and I could tear it down and rebuild it 
differently later on.
