def iterchildren(treectrl, node):
    cid, citem = treectrl.GetFirstChild(node)
    while cid.IsOk(): 
        yield cid
        cid, citem = treectrl.GetNextChild(node, citem)


# sample usage
for i in iterchildren(myTreeControl, someNode):
    print myTreeControl.GetItemText(i)

Discussion

I wrote this generator to avoid the copying/pasting/editing of boilerplate code to iterate over the children of an item in a wxTreeCtrl. Since I haven't run across a similar example, I thought I'd share it here.
