Usually, you can use a separate script file to store the
  implementaion of each new widget class. If you have several of those
  files, it will be a good idea to group the files into a single
  directory and create a 
tclIndex file for them so that the new
  classes can be auto-loaded.
   Suppose you have put the class files into the directory 
/usr/my/tix/classes. You can create the tclIndex file using
  the 
tools/tixindex program that comes with Tix:
  cd /usr/my/tix/classes/usr/my/Tix8.1/tools/tixindex *.tcl
    The 
tclIndex file must be created by the tixindex  program. You cannot use the standard 
auto_mkindex command
  that comes with Tcl.
   Once you have created the 
tclIndex file, you can use your new
  widget classes by auto-loading. Here is a small demo program that
  uses the new TixArrowButton class:
  #!/usr/local/bin/tixwishlappend auto_path /usr/my/tix/classes
# Now I can use my TixArrowButton class!
#
tixArrowButton .arr -direction n
pack .arr
