I am pleased to announce version 1.0 of the toggle switch widget package Tsw.
What is Tsw?
------------
Tsw is a library package for Tcl/Tk versions 8.6 or higher. If the
version is 8.6 then in addition it is required that the tksvg extension
can be loaded into the interpreter (Tk versions 8.7 and 9.0 or higher
have built-in SVG support). The package is written in pure Tcl/Tk code
and contains:
- the implementation of the "toggleswitch" mega-widget, including a
general utility module for mega-widgets;
- two richly commented demo scripts containing the typical steps
needed to create and handle toggleswitch widgets;
- a tutorial in HTML format;
- a reference page in HTML format.
How to get it?
--------------
Tsw is available for free download from the Web page
https://www.nemethi.de
The distribution file is "tsw1.0.tar.gz" for UNIX and "tsw1_0.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 "tsw1.0.tar.gz":
gunzip -c tsw1.0.tar.gz | tar -xf -
On most UNIX systems this can be replaced with
tar -zxf tsw1.0.tar.gz
Both commands will create a directory named "tsw1.0", with the
subdirectories "demos", "doc", and "scripts".
On Windows, use WinZip or some other program capable of unpacking the distribution file "tsw1_0.zip" into the directory "tsw1.0", 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.
