**1 - If the Width or Height of the list widget is zero (0) then the value
is set to the minimum size necessay to fit the entire list.
If both Width and Height are zero then they are adjusted to fit the
entire list that is created width the number of default columns
specified in the defaultColumns resource.
**2 - This is an array of strings the specify elements of the list.
This resource must be specified.
(What good is a list widget without a list?? :-)
**3 - Longest is the length of the widest string in pixels.
**4 - If either of these values are zero (0) then the list widget calculates
the correct value.
(This allows you to make startup faster if you already have
this information calculated)
NOTE: If the numberStrings value is zero the list must
be NULL terminated.
**5 - By setting the List.Columns resource you can force the application to
have a given number of columns.
**6 - This returns the name and index of the item selected in an
XawListReturnStruct that is pointed to by the client_data
in the CallbackProc.
