Hi.
This is kind of a cross-product question, having to do with accessibility
on Linux using ATK (AT-SPI).
However, I think it really boils down to a python question: "How do I pass
an integer by reference to a C function?"
I am using Accerciser (http://live.gnome.org/Accerciser), an accessibility
testing tool that has an ipython console.
It uses pyatspi to interact with AT-SPI through pyORBit.
I need to test my handling of
atk_editable_text_insert_text(AtkEditableText *text, const gchar *string,
gint length, gint *position).
In the example below, the variable 'acc' has been bound (by Accerciser) to
an accessible object that implements the AtkEditableText interface.
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'."
Has anyone done this? If so, then how is it done?
Here's a sample of the things I tried:
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)
