We're just starting to use InterViews and are having some
fun.  What we'd like to do is to build a TableBrowser or
Chooser.  That is, we have some data that exists as a
series of string tuples or fields.  We want to display
each tuple a line at a time and have one scrollbar that
scrolls the whole tuple.  When one selects a field, the
whole tuple would be available for updating/editing.  I
envision something like:

  ----------------------------------------------------
  |                  Title                           |
  |                                                  |
  |   Hdr 1   Hdr 2  Hdr 3         Hdr 4             |
  |   ------- ------ ------------- ------- ^         |
  |   |     | |    | |           | |     | *         |
  |   |     | |    | |           | |     | |         |
  |   |     | |    | |           | |     | v         |
  |   ------- ------ ------------- -------  \..scroll for all fields
  |                   <--*------->                   |
  |                               \..(for just this field
  |       Field 1: _______________                   |
  |       Field 2: _______________    <Add>          |
  |       Field 3: _______________    <Delete>       |
  |       Field 4: _______________    <Change>       |
  ----------------------------------------------------

The question is: Does anyone have any hints on what
would be the best way to develop this class(es)? I have 
taken FileChooser, modified to call multiple 
StringBrowsers but am having trouble with the callbacks 
and getting the scrollbar to work with multiple 
StringBrowsers.
