NAME
       tkvars - Variables used or set by Tk


DESCRIPTION
       The  following  STk  variables  are either set or used by Tk at various
       times in its execution:

       *tk-patch-level*
              Contains a string which represent the current  patch  level  for
              Tk.   The  patch  level  is  incremented for each new release or
              patch, and it uniquely identifies an official version of Tk.

       *tk-strict-motif*
              This variable is set to #f by default.  If an  application  sets
              it  to  a  true  value, then Tk attempts to adhere as closely as
              possible to Motif look-and-feel standards.  For example,  active
              elements  such  as buttons and scrollbar sliders will not change
              color when the pointer passes over them.

       *tk-version*   Tk sets this variable in the interpreter for each appli-
                      cation.   The  value  of this variable is a string which
                      holds the current version number of the  Tk  library  in
                      the  form  major.minor.   Major  and minor are integers.
                      The major version number increases  in  any  Tk  release
                      that  includes  changes that are not backward compatible
                      (i.e. whenever existing Tk applications and scripts  may
                      have to change to work with the new release).  The minor
                      version number increases with each new  release  of  Tk,
                      except that it resets to zero whenever the major version
                      number changes.
