GTK 2 has a lot of new widget classes. Most of the new classes do something
better or a different way than an old class; and so the old widgets were
deprecated in favor of the new one.
To keep backward compatibility (BC), the old widgets can
still be used, but are likely to be removed in GTK 3 or so. That means
that you don't have to rewrite your old programs totally, but still can
use them without too much changes. However, you really shouldn't use any
of the deprecated widgets in newly written code. Don't do it.
