SetBackgroundColor doesn't work for me
Hi, I'm on Linux Ubuntu Breezy with wxPython 2.6.1 and Python 2.4.1 installed. I've made an app, but the BackgroundColors won't work on any of my ListBoxes, they only work with Windows XP.

ini files and plugins
Hi, I've made a basic LaTeX file editor in wxPython, but now I wanted to add it some features : 1 - create a sort of ini file where I can put the user configuration that will load itself on the application startup ; 2 - a simple plugin system with python files ( maybe to add new langages, etc.) ; I'm looking for simple articles, modules or code snippets on these subjects; thanks, 6TooL9 -- http://mail.python.org/mailman/listinfo/python-list

Re: The Python Papers Edition One
I've recently tried the docutils's reST module with Pygments ( to highlight Python sources), so you can have LaTeX + HTML + PDF output (You can see what it renders here : h**p://kib2.free.fr/geoPyX/geoPyX.html ). It worked fine, but needs a little work to suit your needs (you'll have to write your own CSS, and maybe your LaTeX preambule ). For OpenOffice, a friend wrote a little Python script that colourize a Python source inside a document. I think It will be possible to write your own for HTML output, but the ooo API docs aren't well documented for Python. Chears, 6Tool9 -- http://mail.python.org/mailman/listinfo/python-list
Finding the carret position in a regular expression
Hi, supposed I've got the following text : mytext = "for in :" with the following simple pattern : pattern = "<[a-z]+>" I use re.findall(pattern, mytext) wich returns : ['',''] Now, I want my prog to return the positions of the returned list elements, ie : was found at position 5 in mytext was found at position 16 in mytext How can I implement this ?

But what does > paper.draw() actually do with the drawable object? Call a draw method > within it? No, actually the paper instance is a subclass of a canvas from an external module. And this one have a stroke() method. In reading your comments, I think it's now clear that I must get back and let any primitive have an inner draw() method ( a subclass of Drawable object in our case). > If so, that is when you should pass the paper instance (or > just the part needed -- clipping rectangle perhaps?). In fact, my approach was a bad one : in initialising the paper instance, I was already clipping it. If I wrote : p = Paper(-5,-5,5,5), all drawings made on that paper will be clipped inside a rectangle with lower-left corner (-5,-5) and upper-right corner (5,5). Now, I think it's better to clip after all primitives have been added to the paper. > > The actual implementation of draw() for each primitive will have > to handle clipping to the boundaries of the Canvas object that is passed > to it. > > You'll notice that the only place the primitive needs to know > about the canvas is in its specific draw method.

Parsing nested constructs
Hi,
I need to parse some source with nested parenthesis, like this :
>cut-
{
{item1}
{
{item2}
{item3}
}
}
>cut-
In fact I'd like to get all start indexes of items and their end (or
lenght).
I know regexps are rather limited for this type of problems.
I don't need an external module.
What would you suggest me ?

cyclic iterators ?
Hi, Let say I've got a simple list like my_list = [ 'a', ',b', 'c' ]. We can have an iterator from it by k = iter( my_list), then we can access each of her (his ?) element by k.next(), etc. Now, I just wanted k to have the following cyclic behaviour (without rising the ) : >> k.next() 'a' >> k.next() 'b' >> k.next() 'c' >> k.next() -> not raising StopIteration error 'a' >> k.next() 'b' etc. I've tried something like this to have a cyclic iterator without sucess: def iterate_mylist(my_list): k = len((my_list) i=0 while i <= k : yield my_list[i] i += 1 i = 0 yield my_list[0] I missed something, but I don't know what exactly.
