Building a GUI Toolkit
Hi I was thinking of writing a GUI toolkit from scratch using a basic '2D library'. I have already come across the Widget Construction Kit. My main question is: Could I build a GUI toolkit of reasonable performance with the Widget Construction Kit, would it still feel more or less lightweight? By reasonable I mean that the user wouldn't think of the interface as being slow or unresponsive. I've also thought of using pyglet to build widgets with, but this would seem to be overkill. As a side question: by using opengl, the work would be delegated to the GPU rather than the CPU; is this always a good thing, or does it have downsides as well (performance, power usage, ...)? Are there any other libraries that may be of interest to me? Thanks in advance -- http://mail.python.org/mailman/listinfo/python-list

Thanks in advance It probably depends on how low level you want to go, I have pondered about the possibility myself to have an all python(ic) gui toolkit, capable of writing a (x11) windowing manager itself with. But I decided that using tkinter and just live with its rough corners is more bang for the buck for me than to reimplement tkinter badly. Rather than writing a windowing toolkit from the low-level, I would rather like to see some wrapper for existing windowing toolkit which uses more pythonic idioms. Most popular python GUI toolkit currently in use are only a simple thin wrapper over the library they're wrapping and exposes a lot of the design considerations of the language that the toolkit was originally written in. Yes, even Tkinter that comes with the standard lib is a hack on top of python and looks much more Tcl-ish than pythonic. I have always had the idea of writing a windowing toolkit wrapper that creatively uses python features for maximum expressiveness (e.g. decorator, with-statement, for-each), but never got the time to write anything like that. When (or if) I'd finish this low-level gui toolkit, I'd incorporate it into my original plans, which were: writing a library that provides the programmer with 1 API, yet can display the GUI in a terminal (curses), on the desktop(X/win32/...) or in your web browser (DHTML). Terminal support would likely be very limited though. I think I'll go ahead and try to write a wrapper around pyglet and start writing some basic widgets. -- http://mail.python.org/mailman/listinfo/python-list
Python3: API Documentation generator
Hi all I've just switched to python3 and it turns out my current API documentation generator (epydoc) no longer works. I am looking for a tool that reads the docstrings of all classes, ... in my project and turns it into HTML documentation. Thanks for your time limyreth -- http://mail.python.org/mailman/listinfo/python-list

Sphinx (http://sphinx.pocoo.org/ ) is the new gold standard. You'll
want to enable the `autodoc` extension:
http://sphinx.pocoo.org/ext/autodoc.html

I tried, but it fails to run through python code that's not backwards
compatible with older python versions.
It fails with: ...autodoc can't import/find module 'pytilities', it
reported error: "invalid syntax (overload.py, line 55)"...
This is line 55 (runs in python3, not in python):
def process_args(self, *args, kwargs={})

As far as I'm aware, autodoc works by importing the modules and then
reading doctext straight from the __doc__ attributes.
So the module in question has to import correctly in whatever
interpreter Sphinx is using. You probably need to install Sphinx with
python3 to get it to use the right interpreter. If you're using
easy_install or pip, check if you have an easy_install-3.1 or pip-3.1
(or similar) script installed.
Sorry for the late reaction, but I still have trouble getting sphinx to
work with python3.
I downloaded the latest version at PyPI:
http://pypi.python.org/pypi/Sphinx/1.0.4
Ran:
python3 setup.py
And it failed with a syntax error at line 50 which happens to be an
old-styled print statement stating it requires at least py2.4.
I'd find it odd that the python3 documentation would refer to sphinx as
a good tool if the tool wouldn't support it, so am I downloading the
wrong package or ...?
Thanks in advance
