[maemo-developers] Writing a Python binding of a C library that uses GObject

[From: Andrea Grandi]

Hi all,

I'm writing a Python binding for a C library that runs on Maemo and,
since it's the first binding I write, I've some questions.

I've read the chapter "Extending Python with C" in a couple of manuals
and I've read the online documentation too, but some parts are no
covered yet.
At the moment I'm able to create a simple Python binding for a C
library that returns simple type of data (char, int, double, void,
ecc....) but the library I've to manage with is more complex: it makes
a huge use of GObject and often its methods don't return simple types,
but complex objects.

I know I can use PyGObject when I've to call GObject functions (for
example g_signal_connect ecc....), but what if I've to return an
object?
Please note: those object I'm talking about inherit from GObject.

Is there a "manual" way to do this job?
Someone suggested me to look for "GObject Introspection", but I
couldn't find much examples... how introspection could help me?
Is there a way to do it without introspection?

I'd like to have a working example in both way.

Thanks for your support.

Best regards,
