My understanding is: the motion_notify event means "there are motion
events for you to look at."  You then need to retrieve the events
using gdk_input_window_get_pointer, or gdk_input_motion_events.


model_darea_motion_event (GtkWidget *widget,
			  GdkEventMotion *event)
  gdouble		x, y;
  GdkModifierType	mask;
  gint			row, col, hit;
  gchar			pos_str[100];

  /* TODO: display extra information about the element under the
   * pointer. */
  gdk_input_window_get_pointer (event->window, event->deviceid,
				&x, &y, NULL, NULL, NULL,
  hit = screen_to_element (x, y, &row, &col);
