***checkButtonToggle***
'''Current Version: 2.56.2 (2020-10-6-231)'''
SourceForge: https://sourceforge.net/projects/tcl-checkbuttontoggle/
[bll] 2021-6-21: Version 2.6.2 supports Tcl/Tk version 8.7.
[bll] 2020-10-25: Version 2.3 is updated to work with awthemes 9.4.2.
Version 2.4 adds support for the awthemes scale.factor setting.
Version 2.5 adds support for the yaru theme.
(image below has been updated, it will take some time for the cache to clear. See the image on sourceforge).
[bll] 2019-12-3: Version 2.0 has reworked handling of .svg files and better colors. Mac OS will use the accent color.
[bll] 2019-10-4. Version 1.11 has reworked graphics so that the [tksvg] package may be used. If
you have the tksvg package available, the togglei/[[0-9]]* folders may be removed.
[bll] 2016-4-26. This code provides an alternative styling of [ttk::checkbutton] as a toggle switch.
This style of switch is becoming more common in user interfaces. There are currently 13 different
switch styles in order to support the 30 different ttk themes. The package will select a toggle
switch style upon load, and a bind to <<ThemeChanged>> sets it when the theme is changed.
The user can set any of the themes as a default and can use multiple themes.
The package should be "required" after [tk scaling] is set

[bll] 2016-5-2. I have updated the package to include multiple sizes of images and

No idea if I got the scaling quite right, but a quick test looks ok.

****Discussion****
[aspect] 2016-04-28: beautiful widget and a '''very''' nice example of how to do custom layout with [ttk].
One question - is there any particular reason you excluded `Checkbutton.focus` from the layout? I much prefer having it to aid keyboard navigation & accessibility.
Adding it back as a parent of the new `indicator` element ''seems'' to work, but I've only tested very roughly with the provided demo.
[bll] 2016-4-27: I copied a layout from another theme.
Sorry, did not check the original.
I have updated the code below to match the default ttk::checkbutton.
----
[JOB] Thank you [bll] for providing the source.
Just like to let you know, that there is something going wrong with the images provided in the package.
======
Error in startup script:
compressed data after stream finalize in PNG data
while executing
image create photo -data $imgdata($dnm)
...
======
Running on windows with a plain ActiveState installation.
[bll] 2015-5-3: Let me research this. It works for me in some instances and not others. This is quite odd. It works as part of my application, but it does not work as a standalone script. I found this:
http://rkeene.org/projects/tcl/tk.fossil/info/c648c8dad1%|%http://rkeene.org/projects/tcl/tk.fossil/info/c648c8dad1%|%
And ActiveState still doesn't have 8.6.5 out.
Always requiring the Img package works.
I have updated the code to require the Img package for Tcl <8.6.5.

I downloaded the source code and the demo works fine. Some variants look rather similar, but that may be my display.
[bll] 2016-5-3: I think it is how I wrote the demo code. It lists the 7 styles (variants), then displays the toggle switch that would be displayed for any themes that are loaded. Which, being standard themes, all use the same style/variant.

'''[JOB] - 2016-05-03'''
Downloaded again and it works flawlessly on windows.
I got more adventurous and tested it on OSX too, but here the checkbutton is only a grey box. Have not investigated any further.
Looks on windows very promising. Thank you very much [bll].
[bll] 2016-5-3: Works ok on the Mac for me.

***Usage***
[HaO] 2020-10-20: Thanks, Brad, for the beautiful widget.
The distribution contains png images in many resolutions. If [tksvg] is present, they may be deleted ( folders togglei/[[0-9]]+ ).
My personal initialization sequence with awdark is:
======
package require awthemes
::themeutils::setThemeColors awdark scale.factor $myCurrentfactor
package require awdark
package require checkButtonToggle
======
For efficiency, "checkButtonToggle" is loaded after the choice of the theme to win an initialisation round.
([bll] 2020-10-20 Specifically, if 'checkButtonToggle' is loaded after the `ttk::style theme use ...`, 'checkButtonToggle' will
only initialize one theme's set of images rather than two themes).
To display a toggle button, the style "Toggle.TCheckbutton" should be used:
======
::ttk::checkbutton .c -style Toggle.TCheckbutton
======
