Tcl Tk Download Mac

Download Tcl/Tk Aqua Batteries-Included for free. Tcl/Tk Aqua Batteries-Included is a binary distribution of the Mac OS X native Tcl/Tk and many popular extensions.

  • Tk is a graphical user interface toolkit that takes developing desktop applications to a higher level than conventional approaches. Tk is the standard GUI not only for Tcl, but for many other dynamic languages, and can produce rich, native applications that run unchanged across Windows, Mac OS X, Linux and more.
  • Download the latest version for windows installer from the list of Active Tcl/Tk binaries available. Active Tcl/Tk community edition is free for personal use. Run the downloaded executable to install the Tcl and Tk, which can be done by following the on screen instructions.

Prerequisites

Tcl Tk Install

You should have Tcl and Tk installed on your computer. Togl works with Tcl/Tk version 8.1 and up (all recent testing has been with version 8.4). The Mac OS X version requires version 8.4 (note: versions 8.4.12 and 8.4.13 have a bug when unmapping Togl widgets).

You must also have OpenGL or Mesa (a free alternative to OpenGL with the same API) installed on your computer.

And one should be familiar with Tcl, Tk, OpenGL, and C programming to use Togl effectively.

Downloading Togl

Togl can be downloaded from SourceForge Files page.

Several prebuilt binary distributions are available as well as a source distribution.

Installing Togl

Installing prebuild binaries

Prebuilt binaries provide a Togl2.0 directory, the togl.h, togl_ws.h and toglDecls.h include files, and the togl stub library (libToglstub2.0.a or Toglstub20.lib, etc). The Togl2.0 directory needs to copied into one of the directories on Tcl's package path (type puts $auto_path in the Tcl interpreter to see the list of directories). If you have C code that needs to access Togl's subroutines directly, place the include file in the same place as Tcl's include file and the stub library in the same place as Tcl's stub library.

Installing from source

Togl uses the Tcl Extension Architecture to be able to build on the same platforms Tcl can be built on. In addition to the Togl source, you will need to have the Tcl and Tk source distributions because not all installations have the needed Tcl and Tk internal header files.

How you link with Togl depends on how you're planning to use it. There are basically three ways of using Togl with your application:

  • Install the Togl shared library and pkgIndex.tcl file (using make install) and link to the Togl stubs library with your executable or shared library. In this case you must call Togl_InitStubs() (and probably Tcl_InitStubs() — Tk_InitStubs is only needed if you call Tk functions). This is the way the included Togl examples are built.
  • Link to the Togl shared library or 'compile in' the Togl object files with your executable or shared library. In this case you must call Togl_Init() from your C code to initialize Togl.
  • Install the Togl shared library and pkgIndex.tcl file (using make install) and then load it using Tcl commands or Tcl_PkgRequire(). Then use Tcl commands to create and manipulate the Togl widget.
Since Togl is compiled into a shared library using the Tcl/Tk stubs-interface, the same binary can be used with any version of Tck/Tk from 8.1 and up. See README.stubs for more info.

Specific platform notes follow:

Unix/X11 usage

Unix/X systems only need the public Tcl/Tk include files. Just configure, make, and optionally make install.

Windows 95/NT/2000/XP usage

Windows platforms need tkWinInt.h and other internal Tk header files. So you need a Tcl/Tk source distribution in addition to the Togl distribution (or copy over the various include files).

Here's the minimal way to build Togl with Tcl/Tk using the gcc that is distributed as part of the cygwin tools (Microsoft's compilers work too):

The resulting Togl20.dll and pkgIndex.tcl should be installed into your Tcl installation just like any other package.

If you change all of the above make's to make install instead, then the Togl package is installed correctly.

Mac OS X usage

These special instructions are for building the Aqua version of Togl. Mac OS X needs tkMacOSXInt.h and other internal Tk header files. Unfortunately, the Tcl and Tk frameworks that Apple distributes are missing the internal headers. So you need a Tcl/Tk source distribution in addition to the Togl distribution (or copy over the various include files). You would probably want a newer version of Tcl and Tk anyway because each minor revision of 8.4 has many Aqua bug fixes.

Here's one way to build Tcl, Tk, and Togl on Mac OS X (assuming they are all in the same directory) to install in your home directory:

Latest Software Releases

Tcl software download

This tutorial will quickly get you up and running with the latest Tk from Python, Tcl, Ruby, and Perl on macOS, Windows, or Linux. It provides all the essentials about core Tk concepts, the various widgets, layout, events and more that you need for your application.

If you have an older version of Tcl / Tk Aqua, you'll benefit from upgrading. There have been many usability improvements since the version that comes shipped with MacOS X Leopard. I tried the link and it redirects to Daniel A. Steffen LinkedIn page, who is the lead developer of Tcl/Tk for Mac, as far as I understand. I tried googling to find. TK-ARCHITECT is a true type format with regular style available for MAC & PC.Its character map contain uppercase alphabets and numbers. Family: TK-ARCHITECT TK-ARCHITECT font has been downloaded (21487) times. A built-in version of Tcl/Tk 8.6 will be used. If you are using macOS 10.6 or later, the Apple-supplied Tcl/Tk 8.5 has serious bugs that can cause application crashes. If you wish to use IDLE or Tkinter, do not use the Apple-supplied Pythons.

There are several options available for obtaining Tcl/Tk. Theseare listed below.

Operating System Packages

Tcl/tk For Mac

Most Unix / Linux operating system distributions, as well as Mac OS X,include Tcl/Tk. If not already installed, you can use your system'spackage manager to install the appropriate packages. For example,on a Debian system, you can type

to install Tcl. Note than some components, even including Tk,man pages and C libraries may be separate packages and installedin a similar manner.

To check the version installed, start Tcl/Tk(usually via running 'tclsh' or 'wish' from a command line),and typing

Tk For C++

This will tell you what version you're running.

If you do not have privileges to install software or if you needa newer version than the one provided by the system, you may useone of the alternative means of obtaining Tcl as described below.

Binary Distributions

Pre-built Tcl distributions for many common platforms are availablefor download. These include both traditional installers as well assingle file 'download and run' executables. SeeBinary distributions.
