IDE for eog development

["Christoph 'Gigi' Fuchs" <dergigi gmail com>]

Hi everybody,
I would like to hack on eog for a bit and I would like to ask you one question:

-- What IDE do you use to develop C programs like eog?

If you only use a editor like vim/emacs I would like to know that too
- just out of curiosity.

Thanks in advance,
Gigi
