Re: Help in wxpython
Madhura, Sorry to be a bit off-topic, but, I would really recommend you to use pygtk instead of wx. For one thing, the developers at pygtk are very active (they have their mailing list as well ) and it comes by default with python on almost all linux distros. You can also easily install it on windows. Most important, the api for pygtk is closely similar to wx. Not to mention the quick responses you will get with pygtk related problems. If you want to include the Mac in your distribution, PyGtk isn't a good choice. Native support is quite experimental at this point, which basically means you'll be running it under X11. (WingIDE's Mac version runs on PyGTK, and it doesn't feel native at all.) -- Kevin Walzer Code by Kevin http://www.codebykevin.com -- http://mail.python.org/mailman/listinfo/python-list

There is currently an on-going documentation initiative going on for wxPython. Robin Dunn is doing some work on it that will allow much easier documentation patching (as I understand it), so that should get better. Also, I am slowly working my way through wxPython many widgets and doing tutorials on them on my blog, which I then stick in the official wxPython wiki if I think the article is good enough. --- Mike Driscoll Blog: http://blog.pythonlibrary.org -- http://mail.python.org/mailman/listinfo/python-list

You can also easily install it on windows. wxPython has some very active developers as well, but the core isn't released all that often. I think this may be caused somewhat by the slow release cycle of wx itself though. > > Most important, the api for pygtk is closely similar to wx. > Not to mention the quick responses you will get with pygtk related > problems.

The main drawbacks are that wxWidgets sucks compared to GTK or Qt (mostly due to being modelled on the Win32 API, which itself sucks compared to most Unix/X11 toolkits), and that wxPython is woefully under-documented (whereas PyGTK is better documented than GTK itself).

I recommend writing your own C extension module to access GDI using ; it's ugly, it's non-cross-platform, it gets you bashed for reinventing the wheel, and it's buggy. Five thumbs up! (err...

As the traceback suggests, self.buffer does not exist. You need to write self.Buffer. I did not have a further look or try the code. Did you have a look at the wxPython demo? The demo "Core Windows/Controls -> ScrolledWindow" is probably very similar to what you want.
