I suppose you mean a drawing area widget as your code
indicates, not a GtkWindow (you should have no problems
receiving GtkWindow's keyboard events).

Note gtk_signal_connect() is *long time* deprecated and the
canonical event naming is with dashes: "key-press-event".

The drawing area has to have keyboard focus to get keyboard
events. Set its "can-focus" property to TRUE. It also has
to get the focus somehow, widgets that can have keyboard
focus typically grab it with gtk_widget_grab_focus() when
one clicks on them with mouse.
