Well, I not so new in gtk+. I'm here more than a year. This thread is
just to clarify a question that's not clarify for me, because I've
never been behind the low level of a window system...

And yes, I agree that search on 60 MB of sourcecode is a good way to
clarify this, so I came here and created this thread.

Thanks for all that respond my question, it's now clear to me.
