Version 38 of Visual Tcl

Updated 2008-09-29 09:14:32 by Tristan

The name Visual Tcl is, unfortunately, such an obvious one that it has been used by a few things. The most common usage is the Stewart Allen GUI building tool which is listed below.

SCO toolkit

There is an ancient SCO toolkit known as Visual Tcl which had nothing to do with vtcl the graphical building tool. It was a product/extension which created a Motif GUI interface, as well as an ASCII interface for CUI programs.

"Aug 02, 1999

"The Visual Tcl/Tk project has been terminated! Because of the work of Stewart Allen's project, I see no need to provide a duplication of effort. Stewart's development moved far ahead of my Visual Tcl/Tk project. I simply wanted to see an effective FREE GUI for Tcl/Tk available to the masses to provide momentum for Linux development. In my opinion, Stewart Allen's efforts more than meet that goal. If you want a good FREE GUI development environment for Tcl/Tk please go to Stewart Allen's Visual Tcl site"

Clif Flynt in the Tcl chatroom on 2003-06-27: "I've reworked some vtcl output. The script performance can be improved a lot by using 'option add' instead of all the -font xx -fg yy options in the widget creations."

This tool was included in O'Reilly's now defunct Mac Open Source Software Directory

The SCALD project uses Visual Tcl:

RLH: Is Visual Tcl from still being maintained? It is a really nice UI builder.

LV Tthere has been mailing list discussions on the site. But I don't know how much maintaining has been done. But then, if it works properly, there won't be a need for a lot of fixes.

06/08/04 DC - Visual Tcl is not currently being actively maintained as the two developers who were working on it have moved on. Christian Gavin moved on to pursue other interests, and I lost interest in maintaining vTcl in its current form. I have, however, begun work on a rewrite of vTcl that will appear eventually as Tk Designer. I'm renaming and rewriting the code so as to get out from under the GPL license. This may happen a lot quicker if I can get the permission of the copyright holder (Stuart Allen) to change the license to BSD, which is my ultimate goal.

Larry Smith Umm..."renaming and rewriting" will not get you "out from under the GPL". If you started with GPL code, no amount of renaming and rewriting will enable you to change the license. The GPL is viral in the sense that any derived work must also be GPL'd. That's what the GPL is for. Even if the final version ends up with all the code different, the basic structure will still be there and will still be GPL'd.

The only legal way to nullify the GPL is to get the copyright owner to change it for you, or to write an entirely new program from scratch. See [L1 ].

HJG 2005-11-11: It looks like work on vtcl has resumed:

RLH Well what do you know!

SJPEDRO 2007-08-14: FYI Work is ongoing:

Roy Keene I have made some vTcl (version 1.6.1a1) starpacks for various platforms, they are available at . Feel free to request additional platforms.

[Add info about tricks for using vtcl, benefits, etc.]

Tristan 2008-09-28: Please visit the Visual Tcl Binary Project HomePage: . This version had more i18n support, and Tile widgets, VU widgets, TkVideo widget, etc.

That only seems to hold some binary downloads (no sources), and most of the webpage text is in some CJK language. Is that what was expected?

Lectus 2008-09-28: Tile widgets in Visual Tcl? This is very nice! I wonder if anyone is still developing Visual Tcl? This is really good tool and should not be abandoned.

Tristan 2008-09-29: vtcl-bin is a starpacks.

vtcl-bin source:

    tar zxvf vtcl-20080627-linux.tar.gz
    gunzip tclkit-linux-x86.gz
    chmod +x tclkit-linux-x86
    ./tclkit-linux-x86 sdx.kit unwrap vtcl
    cd vtcl.vfs
