code: @Override
      public void eventCallback(String eventName, Object eventData) {
          String pane = StrUtil.piece(eventName, ".", 2);
          Label lbl = getLabel(pane.isEmpty() ? "default" : pane);
          lbl.setLabel(eventData.toString());
          lbl.setHint(eventData.toString());
      }
docs: Handler for the STATUS event. The second level of the event name identifies the pane where
  the status information (the event data) is to be displayed. For example, the event
  STATUS.TIMING would display the status information in the pane whose associated label has an
  id of "TIMING", creating one dynamically if necessary. If there is no second level event
  name, the default pane is used.
