GtkDrawingArea area does not accept keyboard focus. If it's
the only widget in the window it gets the keyboard events
anyway, but if there are widgets that accept keyboard focus
(at least one), then the widget with keyboard focus gets
these events -- and this is never your GtkDrawingArea.
You have to make it accept focus:
GTK_WIDGET_SET_FLAGS(widget, GTK_CAN_FOCUS);
In additon you probably want to grab focus when the user
clicks on it with mouse, i.e. call
if (!GTK_WIDGET_HAS_FOCUS(widget))
gtk_widget_grab_focus(widget);
in the "button-press-event" handler.

P.S.: If you are writing something nontrivial, it might make
more sense to subclass GtkWiget directly -- if basing
widgets on GtkDrawingArea would be such a great idea, Gtk+
itself would be full of such widgets, isn't it?
