You can't just draw on widgets, it won't work properly even if you get
the size.

If you want a border around each widget in a table, the best way to do
it is to write a simple subclass of GtkBin that draws such a
border. This widget should be absolutely trivial; override
size_request to return the size of the child plus the size of your
border, override size_allocate to give the child your allocation minus
the size of the border, override expose/draw to draw your border and
then chain up to the GtkBin default implementations of expose/draw to
draw the child widget. That should be it, maybe I forgot a couple
details. Anyway GtkObject boilerplate plus 4 or so trivial functions.
