Most code (but not all) in gtk-demo uses this version...

but most of the code in the examples directory, come with the G_OBJECT  
cast...

Excellent, one less to choose from... I am coming from GTK 1, that's 
why... ;-)

It's interesting anyway, that compiling with
       -DG_DISABLE_DEPRECATED          \
       -DGDK_DISABLE_DEPRECATED        \
       -DGDK_PIXBUF_DISABLE_DEPRECATED \
       -DGTK_DISABLE_DEPRECATED
activated, no warning is reported, and the signal works just fine,
that's why I didn't notice that this was a no no....

Anyway, GtkObject still exists (I supose mostly because of GtkAdjustment
and other old structures?): 
<http://library.gnome.org/devel/gtk/stable/GtkAdjustment.html>
http://library.gnome.org/devel/gtk/stable/GtkObject.html

pkg-config --modversion gtk+-2.0:
Gtk 2.12.8

Thanks a lot,
Carlos
