• ANNOUNCE: Toggle switch widget package Tsw 1.1

    From nemethi@csaba.nemethi@t-online.de to comp.lang.tcl on Tue Jun 10 16:17:21 2025
    From Newsgroup: comp.lang.tcl

    I am pleased to announce version 1.1 of the toggle switch widget package
    Tsw.

    What is new in Tsw 1.1?
    -----------------------

    1. For compatibility with the (ttk::)checkbutton, toggling the widget's
    switch state by changing the value of the variable specified by the
    "-variable" option will no longer cause the script specified by the
    "-command" option to get executed.

    2. For further compatibility with the (ttk::)checkbutton, invoking the
    "switchstate" subcommand with the optional argument now has no effect
    if the widget's "disabled" state flag is set.

    3. Several further improvements in the code and the demo script
    "EditingOpts.tcl".

    4. Extended the reference manual by a section about choosing between
    toggleswitch and (ttk::)checkbutton widgets.

    5. Improved the documentation by extending the CSS stylesheet used in
    the HTML files.

    How to get it?
    --------------

    Tsw is available for free download from the Web page

    https://www.nemethi.de

    The distribution file is "tsw1.1.tar.gz" for UNIX and "tsw1_1.zip" for
    Windows. These files contain the same information, except for the
    additional carriage return character preceding the linefeed at the end
    of each line in the text files for Windows.

    Tsw is also included in tklib, which has the address

    https://core.tcl.tk/tklib

    How to install it?
    ------------------

    Install the package as a subdirectory of one of the directories given
    by the "auto_path" variable. For example, you can install it as a
    subdirectory of the "lib" directory within your Tcl/Tk installation (at
    the same level as the tk8.X or tk9.X subdirectory).

    To install Tsw on UNIX, "cd" to the desired directory and unpack the distribution file "tsw1.1.tar.gz":

    gunzip -c tsw1.1.tar.gz | tar -xf -

    On most UNIX systems this can be replaced with

    tar -zxf tsw1.1.tar.gz

    Both commands will create a directory named "tsw1.1", with the
    subdirectories "demos", "doc", and "scripts".

    On Windows, use WinZip or some other program capable of unpacking the distribution file "tsw1_1.zip" into the directory "tsw1.1", with the subdirectories "demos", "doc", and "scripts".

    How to use it?
    --------------

    To be able to access the commands and variables of the Tsw package, your scripts must contain one of the lines

    package require tsw ?version?
    package require Tsw ?version?

    Since the Tsw package is implemented in its own namespace called "tsw",
    you must either invoke the

    namespace import tsw::toggleswitch

    command to import the only public procedure of the tsw namespace, or use
    the qualified name tsw::toggleswitch. To access Tsw variables, you must
    use qualified names.

    For a detailed description of the commands and variables provided by Tsw
    and of the examples contained in the "demos" directory, see the tutorial "tsw.html" and the reference page "toggleswitch.html", both located in
    the "doc" directory.
