<grin> I guess I thought that
it must be a novice python question... basically, "How do I pass by
reference?"  :)
I have never used python before, so
I figured this ought to be simple, but it doesn't appear to be.

I still haven't figured out how to do
it... perhaps I'll try to find a python mailing list.

Thanks, Steve.

Hi. 

Sorry to ask a novice Accerciser/ipython
question on this list. I did not find an Accerciser mailing list, and the
IRC channel seems inactive 
I thought perhaps a few of you Orca
folks might have experience with this sort of thing. 

I need to test my handling of atk_editable_text_insert_text(AtkEditableText
*text, const gchar *string, gint length, gint *position) by sending insertText
to an object that implements EditableText. 

The problem is that the pesky "position"
parameter wants a pointer to an integer. 

I have tried all sorts of ways to get
Accerciser's iPython console to accept the last parameter, but I always
get: "TypeError: could not marshal arg 'position'." 

At first, I tried just passing in an
integer variable (hoping it was "by reference"), then I tried
passing in a pointer to the variable using the id() function, then I tried
creating a single-value integer array and passing that in... no luck. I
also tried using the array() function, but apparently Accerciser's iPython
does not support that. I also tried various combinations of C-like syntax,
such as &pos and *pos, but the parser didn't like those either. 

Has anyone ever tried to do this? If
so, how did you do it? 

Here's a sample of the things I tried,
fyi: 

In [1]: t=acc.queryEditableText() 
In [2]: t.getText(0,45) 
Out[2]: 'The quick brown fox jumps over
the lazy dog.\n' 
In [3]: t.deleteText(10,15) 
Out[3]: True 
In [4]: t.getText(0,40) 
Out[4]: 'The quick  fox jumps over
the lazy dog.\n' 
In [5]: pos=10 
In [6]: t.insertText("brown",5,pos)
