Re: gtk_object_sink in glade_palette_init

[Philippe Bertin <philippe bertin telenet be>]

Hello,

I maybe didn't express myself well enough. I could understand that a 
reference to an object is taken in order to not have it disappearing 
(/destroyed). But what I actually meant to ask, is : what's the use of 
first adding a reference, (because that's what's happening in my eyes), 
for removing the reference /just the statement after/. Because that's 
what's happening in my understanding.

Beware : I'm not-too-GTK-familiar, so maybe (/probably) I misunderstand 
the meaning of it all.

Kind regards,

PhB
