[wxPython-users] ANN: HyperTreeList Control for wxPython :-D

[Stani's Python Editor]

Hi Andrea!
Happy birthday!
Unfortunately something went wrong with unwrapping your present on 
Ubuntu 7.04. wxPen doesn't seem supported by GTK, as you suggested in 
your comment:

$ python '/home/stani/Desktop/HyperTreeList.zip_FILES/HyperTreeListDemo.py'
Traceback (most recent call last):

main_style, validator)

line 2370, in __init__
    self._dottedPen = wxPen("grey", 0, 0) # Bitmap based pen is not 
supported by GTK!
NameError: global name 'wxPen' is not defined
