I’ve found a nice example here .
The problem is that I can’t get it to work - most likely wx syntax that has changed in the last five years. I am interested in writing a program based on this example, so I would like to learn from it (rather than messing around first with controls I don’t need in my app). I am new to wxPython.
I have emailed the author, but the article is 5 years old…so I’m not holding my breath…
Can any of you guys help me fix it?
Kind regards
Derick
Yes you are right, the page is very old (and uses the old namespace).
Look at the wxPython Demo
(In my case):
C:\Programme\wxPython2.6 Docs and Demos\samples\wxProject\wxProject.py
But nevertheless, also here I saw some tracebacks.
This sample could be checked through again.

The demo seems to work fine - Thanks!
I wonder why it wasn’t updated on the site…or why the tutorial isn’t included with the code? You are right about the tracebacks, it looks like the implementation of the TreeCtl might have changed. Oh well, at least now I have (semi)working source to play with 
Yes you are right, the page is very old (and uses the old namespace).
More like no namespace at all…

Hello Derick,
My advice is to start here:
http://wiki.wxpython.org/index.cgi/Getting_20Started#head-f423bae42bbd4b4495432886d58c04bc99dd58da
It is a better place to start learning

Yep - still working through it. It’s a very good resource, but I want to hit the ground running - I’ve found the best way to learn a new language / library is to actually use it. Especially if, like me, you already have a specific task in mind…

Thanks - bookmarked for later. A bit over my head at the moment, but definitely worth looking into.
Something a bit more bite-sized if there is someone else out there on my level - A good introductory tutorial:

Peter.
you could take a look at an old attempt to rewrite the Getting Started guide:
http://wiki.wxpython.org/index.cgi/GettingStarted
And one more thing... there is this thing called *fear* that will
hinder you, especialy now, when you feel you are a begginer. Don't
worry, the feeling will dissapear, the sooner the better... Use
courage to fight it... or use something like this:
LITANY AGAINST FEAR
I must not fear.
Fear is the mind-killer.
Fear is the little-death that brings total obliteration.
I will face my fear.
I will permit it to pass over me and through me.
And when it has gone past I will turn the inner eye to see its path.
Where the fear has gone there will be nothing.
Only I will remain.
Stuff like this will allow you to overcome the initial fear and
actualy "see" the code. I believe in you... because I was you... Look,
as a courage exercise tell yourself this:
"I will read the entire page, I will download and look at the source
code provided in that page and when I finish I will write on a piece
of paper what I understood and what I failed to understand".
try courage for a change... it feels better 
Peter.

So I have updated wxProject.py
maybe it is getting (so or with some changes) into the next wxPython Distribution.
If the comments are not ok (I'm no native english speaker),

Thank you Chris (for your interest and also for your corrections).

Hello Frank,
I copy/pasted the sample into my editor.
My annotations:
1) I got tab indentation (The python styling says, spaces with
indenation 4 should be used).
2) What I don't understand:
super(MainWindow, self).SetTitle('Editor %s'%self.filename)
Why this circumstantial super method?
I would prefer:
wx.Frame.SetTitle (self, 'Editor %s'%self.filename)
It looks simpler and more clearly-presented
Else it looks nice and you used some not so often
seen concepts (the **thing and the fashion you create
the menus looks also interesting).
BTW: some docstrings more (but this could be a matter of taste of
course).
Cheers,
