I have been trying to develop some tools for work that I am doing but found certain
limitations in the xview capabilities that I would like to overcome.  The O'Reilly
Xview Programming Manual seems to only be moderately complete and high level, so
I haven't been able to find solutions through research.  

What I would like to do and the problems I am experiencing are:

  * dynamically allocate/deallocate choice buttons - when I deallocate a button, it
does not go away.  I have managed to remove the string (which makes it small in my
case).  I have also decreased the PANEL_CHOICE_NCOLS value, but that causes it to be 
placed on a new row.
  * create choice buttons strings using user input - buttons become much too large
and there does not seem to be a way to attach 'continuation arrows' (as with text 
fields).  If I truncate the user input, I then need to store it in its entirety 
elsewher for future reference.
  * get notified on the 'selection/focus' of a window (ie. a single left button
click in a window border - creates a bold corder line) - I have tried most of
the events listed in the Xview Programming Manual, but none of them worked.  Is
there some sort of atomic level that I need to know to do this type of handling?
  * is there some sort of way to associate other data with a xview object that is 
application dependent?

Thanks.
