Thanks for pointing that out, Curt,
now, for such a trivial function I can imagine substituting
it with a Lambda, however, how would I use a more complex
function?
I found out exactly that when not passing any arguments
the function works like this:
def functName(self, sender):
....
pass
(XamlDef.FindName('btnCreate')).Click += functName
This has worked flawlessly, as soon as I need to pass it
an argument. I haven't found a way to do that.
Thanks again, cheers,

The problem is this line:
controls['Button']['btnCreate'].Click += printHello("HELLO WORLD")
This executes the function printHello("HELLO WORLD") and tries to add
the result -- None -- as an event handler. Something like the following
should probably work:
controls['Button']['btnCreate'].Click += lambda s, e: printHello("HELLO
WORLD")

Ok, I now risk being kicked out from this list for
spamming :D but I have to take my chances. Btw: I'm
still waiting for a bung of WPF books to arrive, so,
please bear with me.
Here's a primitive app I'm trying to build in VS2010
using IPy and, to me, the new WPF stuff.
XAML and the Python Code attached.
Now, when I try to build the app, I get an error:
"Event addition expected callable object, got NoneType"
Can anyone explain to me why I'm getting this error?
As I said, I'm more used to WinForms and adding a function
definition to a control this way has always worked. Even
more so as I copied some of the code, incl. the even
addition from this site:
http://www.ironpython.info/index.php/XAML_GUI_Events_Example
Thank you very much (again) in advance, I really do appretiate
all your support.

should probably be updated to not link to the express
version.
You're absolutely right; the "Visual Studio 2010" link on
http://ironpython.net/tools/ now goes to the general VS2010
site (
<http://microsoft.com/visualstudio/>http://microsoft.com/visualstudio/),
and
<http://ironpython.net/tools/download/>http://ironpython.net/tools/download/
now has the installation instructions from the walkthrough,
so that should clear up any confusion.
Is it Isolated shell or Integrated shell?
Niki
