You should always prefer using either gtk_builder_get_object(), or
also using trustable API's like gtk_button_get_image_widget() for instance.
(not sure if thats an existing api, but you get the idea).
I.e. the composition of opaque composite widgets from GTK+ can
change, possibly breaking unwary code which walks through the
hierarchy checking widget types.
Also, the composition of your GtkBuilder file may change, if you always
access the elements by the keys you provide (i.e. the name field right now)
then you wont run into trouble when changing your interface in the future.
