I don't know what are you trying to achieve. If you want to change a 
child of a container, remove the old child and add a new one.

Another method of doing "animation" through a set of images is by using 
a Gtk_Box. Add all images to the box use Hide on all of them and Show on 
the one show.

If you want drawing use Gtk_Drawing_Area, Cairo and event "draw" 
handler. Use Gdk_Pixbuf for drawing a whole image.
