   % The PlaybackButtons and FileSelector GUOs would never normally be used in this way;
   % they are only used here to avoid having to invent further GUOs for TabObjectDemo.
   % In contrast, using a tabobject directly within another tabobject may be appropriate
   % under certain circumstances, providing that this is not confusing for the users.
