MVC in wxPython HELP!

[meonimarco@gmail.com]

Hi to all.
I woud implement MVC with wxPython. Is it possible? Is there anyone
that have experience in this?
The only correct example according to Observer Pattern that i found on
web is not the formal implementation of MVC (is Document/View) and is
implemented with gtk...
How can i translate this gtk example in wx?
Does exist a tutorial, a archive of example or anything about MVC in
wx?
Thanks all!
Sorry for my "italian" english!

The gtk example that i talk about in my previous message is here:

The problem here is that MVC is not a "thing" (or class or whatever) that
can demonstrated once and for all, but a design concept for
GUI-applications.

You can do MVC in _all_ toolkits, and html, and even ncurses. Some toolkits
have "support" built-in in the way that their more complex widgets - like
tables or treeviews - expect a so-called model. That means that instead of
having e.g. a table-row-object that you add to a table and that you fill,
the table will query your model with an interface like this:

class TableModel:
def __len__(self):
....

def column_count(se lf):
....

def get_value(self, row, column):
....


I have very limited experience with wx - but short googling reveals e.g.

wx.lib.mvctree

Note the (Basic)TreeMode l

Basically, you should try and look for wx(Python)-examples that use tree or
list widgets.

See this recent explanation by has:

(The rest of the thread may lead you to more concrete examples as well.)

Can I just suggest you search in Google Groups for the message by
"has" labelled "Re: MVC programming with python (newbie) - please help".
Dated: 7 Jan 2006 07:03:04 -0800. It is one of the nicest short
descriptions of the MVC pattern and why it works.

The link I have is huge, but:

I've inserted returns at two points in the url directly after slashes,
drop tose returns and the associated spaces.
