It's great!
Any plan to include it into the next release of wxPython?

Hi All,

I have released Version 1.1 beta 1 of wxPyPlot for producing simple plots
in wxPython.

Hi there,

I wrote a recursive function that walks through all the branches of
a tree looking for a specific text. If the text is found the item
should be the return value.

This is my code:

def GetTreeItem( self, item, itemtext ):
  if self.tree.GetItemText(item) == itemtext:
    #if succesful item is a value ('print' says it is assigned to a wxTreeItem)
    return item
  cookie = 0
  if self.tree.ItemHasChildren( item ):
    for i in range( 0, self.tree.GetChildrenCount( item, false )):
      if i==0:
        (child, cookie) = self.tree.GetFirstChild(item, cookie)
      else:
        (child, cookie) = self.tree.GetNextChild(item, cookie)
      self.GetTreeItem( child, itemtext )

and here is some code that uses the function:

def UpdateSoiltypesTree(self):
  i = self.GetTreeItem( self.tree.GetRootItem(), "Soil" )
  print i #somehow i = None, even if 'Soil' is a valid itemtext that is found ??

now to the strange part. If I call this function the value of item in GetTreeItem is
assigned to a wxTreeItem if the function succeeds so I expected it to be present
in 'i' in UpdateSoiltypesTree. However.. the returnvalue always seems to be 'None'

Does anybody know why?

Thanks in advance,
Rob

sorry, I see what's wrong.. the recursion is stopped but the
final return value is empty because it uses the first recursion depth.

Sorry for troubling you,
Rob

It's been discussed. I'm just waiting for the go ahead and the samples to drop into the demo.

Your recursive function doesn't return anything unless
self.tree.GetItemText(item) == itemtext in the very first line.
