user/src/com/google/gwt/user/client/ui/SplitLayoutPanel.java:385: if
(layoutData.direction != Direction.CENTER) {
In other parts of the class (e.g. setWidgetMinSize) the fact that
getAssociatedSplitter returns 'null' is used to detect the center
widget. This would simplify this method a lot:

   public void setWidgetHidden(Widget widget, boolean hidden) {
     super.setWidgetHidden(widget, hidden);
     Splitter splitter = getAssociatedSplitter(widget);
     if (splitter != null) {
       // The splitter is null for the center element.
       super.setWidgetHidden(splitter, hidden);
     }
   }
