Version 1.7 2018-7-22

• Added support for the scid* themes.

Version 1.6 2018-4-23

• Added support to check for and use the graphite color theme on Mac OS X.
• 2018-5-10: Now available on SourceForge.

Version 1.5 2016-10-29

• Images have been rebuilt and are much better quality.
• Many different image sizes for different display resolutions. The widget size should match up to your tk scaling setting better.

Version 1.4 2016-5-22

• Updated the images.
• Updated the scaling (now uses 100%/150%/200% rather than 100/150/250)

Version 1.3 2016-5-17

• Remove unnecessary stuff.
• Updated the images.
• Updated the scaling.

bll 2016-5-2. I have updated the package to include multiple sizes of images and depending on the tk scaling value, it changes which set of images gets displayed. No idea if I got the scaling quite right, but a quick test looks ok.

checkButtonToggle demo code

#!/usr/bin/env tclsh

package require Tk
package require checkButtonToggle

proc dodisable { c } {
  variable vars

  if { $vars(disabled.$c) } {
    .cb$c state disabled
  } else {
    .cb$c state !disabled
  }
}

proc setDisplay { c } {
  variable vars

  set vars(onoff.$c) 0
  set vars(disabled.$c) 0

  ttk::label .l$c \
      -text $c

  set tc [string totitle $c]
  ttk::checkbutton .cb$c \
      -variable vars(onoff.$c) \
      -text {} \
      -style $tc.Toggle.TCheckbutton

  ttk::checkbutton .dis$c \
      -variable vars(disabled.$c) \
      -text Disable \
      -command [list dodisable $c]
  grid .l$c .cb$c .dis$c -padx 3p -pady 1p
  grid configure .l$c -sticky e
}

proc demo { } {
  variable vars

  # this is not very interesting unless there are some non-standard themes loaded.
  foreach {c} [lsort [ttk::style theme names]] {
    checkButtonToggle::init $c
    setDisplay $c
  }
}

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

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.
