TreeCtrl GetNextSibling

wxPython Users
1

Hello all,

I loop over items on a tree control using 'GetNextSibling', but when i check if there are more siblings i got an excepction:

h = Tree.GetNextSibling(h)
if h.IsOK() == False:
  
Error: AttributeError: 'TreeItemId' object has no attribute 'IsOK'

The GetNextSibling doc says:

  Returns an invalid tree item if there are no further siblings

but, where is defined de invalid tree item?
How can check if there are more sibligns?

Thanks.

You are checking to late if "h" is a o.k.

if h.IsOK() == False:
    Error: AttributeError: 'TreeItemId' object has no attribute 'IsOK'

What about something along these lines:
        (child, cookie) = tree.GetFirstChild(root)
        while child.IsOk():
            print child
            child = tree.GetNextSibling(child)

Thanks for your reply Werner, but i have the same error:

h = Tree.GetFirstChild(item)[0]
while h.IsOK():
  ....
  h = Tree.GetNextSibling(h)

AttributeError: 'TreeItemId' object has no attribute 'IsOK'

I'm using python 2.5, wx 2.8.0.1 (msw-unicode)
Windows XP
  
???

You got a case problem it should be:
while h.IsOk():

Oops .... Sorry, i put an uppercase 'k'.

Now it's working fine. :slight_smile:

Thanks.

It's IsOk with a lower case 'k'. The object also has a __nonzero__ method so you can just check like this:

  if not h:
    # do something
