Looking for a tree widget with control of text color

[Tom]

Is there a tree widget for wxPython or TKinter that support setting the text
color (foreground or background) for each node?

Ideally it could also be updated dynamically.

I heard that there is a good tree widget in IDLE, called TreeWidget, but I
can't find it.  Do I have the name right?  I found the IDLE source code in
with the Python 1.5.2 source code but there was nothing called TreeWidget
there.

Thanks,

Tom.
