     I am not quite sure, but is THIS a good practice ? XUI and Motif
     are full of instances where one widget munges another one, assuming 
     intimate knowledge of it's internals, rather than documented
     widget methods. This, however, makes any extension to such widget
     set extremely difficult. 
     Yes, it is more difficult to accomplish the required overall toolkit
     functionality without hacks, but I believe that our widget sets
     (be it XUI or Motif) must evolve - and any assumptions one widget
     makes about other widgets today may (and will) prevent any improvements
     tomorrow.
