[pygtk] GPollFD/GSource wrappers [was: Re: iosource]

[Martin Schulze]

I've got it working!

gobject.Source is not functional - you must derive your own class and
define the functions prepare, check and dispatch. See attached example.

If this is actually intended, the error that's being raised should be a
NotImplementedError. Btw, there doesn't seem to be any documentation
around for the GSource/GPollFD wrappers. (Who cares, as long as it works
- and pygobject/pygtk really rocks ;-) )

Regards,

  Martin
