Building the Windows Binaries
  To build Tix on Windows, you must have the following:
  
    
 Visual C++ 4.0 or later; or Borland C++ 4.5 or later. There
    is not yet built-in support for Tix to work with other compilers.
    
 The sources of Tcl/Tk for Windows.
    
 The sources of Tix for Windows.
  
 1. Download the Tcl, Tk and Tix sources 
  You can download latest version of the Tcl8.0, 8.1 8.2 or 8.3 from 
ftp://ftp.scriptics.com/pub ftp://ftp.scriptics.com/pub
  
. There are detailed instructions that comes with these packages
  about compiling them on Windows. Hopefully that will give you a good
  exercise on setting up the environment for compiling Tcl-based
  programs on the Windows platforms.
  You can then get the Tix source distribution at 
http://tix.sourceforget.net/download.html  http://tix.sourceforget.net/download.html
. The ZIP file contains files
  with long file names and must be unzipped by an UNZIP program that
  knows long filenames, such as 
winzip.exe.   You should put the Tcl, Tk and Tix source packages in the same
  directory. For example, my directories look like this: 
      
      C:\Program Files\tcl8.3.5
      C:\Program Files\tk8.3.5
      C:\Program Files\tix-8.1.4
      
 2. Compile Tcl and Tk 
  Follow the instructions that come with Tcl and Tk. If you can
  compile successfully, you would get the following files: 
      
      C:\Program Files\tcl8.3.5\win\Release\tcl83.dll
      C:\Program Files\tcl8.3.5\win\Release\\tclpip83.dll
      C:\Program Files\tk8.3.5\win\Release\\tk83.dll
      
  These are the files you need to run Tix on Windows.
 3. Compile Tix 
   Change to the tix-8.1.4\Win subdirectory. Tix supports several versions
   of Tcl. 
 Versions of Tcl/Tk prior to 8.0 are no longer supported.
 The makefile.bc is for Borland 4.5/5.x,
   The makefile.vc4 is for MSVC 4.x,
   The makefile.vc4 is for MSVC 5.x and 6.x
 Edit the file "common.mak" set set the common settings:
   TCL_VER     = version of Tcl to compile with. Should be either 8.0 8.1 8.2 or
   8.3. You may also have to set the Tk/Tcl patchlevel TCLPATCH.
   For MSVC++, use: nmake -f makefile.vc 
   If you have BC++, use: make -f makefile.bc instead.
  When 
make or nmake finishes, you will get Tix binaries
  inside the build directories. For example, if you compile Tix for
  Tcl 8.0, you will be the following files:
      
      C:\Program Files\tix-8.1.4\win\tcl8.0\tix8183.dll
      C:\Program Files\tix-8.1.4\win\tcl8.0\tix8183.exe
      
  The executable file 
tix831.exe contains Tcl, Tk and Tix. You
  can use it to run an Tix script by:
      
      set TIX_LIBRARY=C:\Program Files\tix-8.1.4\library
      C:\Program Files\tix-8.1.4\win\tcl8.0\tix8183.exe foo.tcl
      
 4. Fixing DLL problems
  You may run into certain problems related to DLL's when you execute
  
tix8183.exe. For example:
  
    
 Windows complains that a DLL, usually tcl83.dll, is not found.
    
 Windows complains that a symbol is missing.
    
 Some weird things happen.
  
  When 
tix8183.exe starts up, it will load in the following DLL's
  
    
tcl83.dll    
tclpip83.dll    
tk83.dll    
tix8183.dll  
  Windows searches for a DLL file by the following order:
  
    
Same directory as executable.
    
Windows system directory.
    
directories in the PATH environment variable.
  
  
  To ensure that the correct DLLs are loaded, you can copy all the
  DLL's used by tix8183.exe into the directory where tix8183.exe is. 
 5. Installing Tix
  You can install Tix into the Tcl installation directory so that you
  can load Tix with the "package require" command and no longer need
  to set the TIX_LIBRARY variable: 
  
    
 Create a directory tix-8.1 under the Tcl installation
    directory, usually in 
C:\Program Files\tcl8.3.5\lib.     
 Copy all the files under tix-8.1.4\library into the
    
C:\Program Files\tcl8.3.5\lib\tix-8.1 directory.     
 Copy the file tix-8.1.4\win\pkgIndex.tcl into the
    
C:\Program Files\tcl8.3.5\lib\tix-8.1 directory. 	 
  
  Now you should be able to start up wish83.exe and execute the
  following command to load in Tix.
      
      package require Tix
      
  Read the file 
Pkg.txttix-8.1.4\docs\Pkg.txt  for more
  info about dynamically loading Tix.
 FAQ's for running Tix on Windows
  
 How do I set an environment variable.  
       You can set it in your DOS window by typing something like
       "
set TIX_LIBRARY=C:\Program Files\tix-8.1.4\library". 
       This will affect that particular DOS window only. If you want 
       the change to affect the whole Windows environment (for example, 
       you want launch 
tix8183.exe by double-clicking on its icon), 
       you must put the commands in your 
AUTOEXEC.BAT file and then
       reboot your machine. 
  
 I get an "out of environment space" error from DOS.  
        Edit your 
CONFIG.SYS file and add the switch
        "
/E:1024" to the SHELL=COMMAND.COM        line. Reboot. This should give you enough env space.
  
 My C compiler says "unrecognized file format tk83.lib" or
  something like that.
       
  
       You compiled 
tk83.lib with VC++ and are compiling Tix
       with Borland C++, or vice versa. Use the same compiler to
       compile all binaries.
