(images will be updated for 9.0; it will take a while for the image cache to clear).

bll 2020-4-27: Added the 'arc' theme.

bll 2020-4-18: The various widget themes have been repackaged as widget "styles".

bll 2020-4-12: 'awthemes' started out as a couple of new themes, awdark and awlight. When tksvg came out, I created scalable versions of awdark and awlight. Helper routines are included to set menu colors, text widget colors and listbox widget colors.

The scalability uses the base tk scaling (it doesn't scale the fonts, those should be set to points and scaled by the application), and an additional application level scaling factor can also be set. A new style with a different scaling factor can be created, including scaled widgets and graphics, used simultaneously with the main style.

Scalable versions of the 'winxpblue' and 'black' themes were added.

As of 2020-4-12 version 7.9, the breeze theme by Maximilian Lika has been added as a scalable theme. A couple of new helper routines to change the graphics/focus color and to change the background color have been added.

 Old News

bll 2020-4-12: Added a scalable breeze theme. Based on Maximilian Lika's breeze theme version 0.8 ( Breeze at github ). New helper routines to change the graphics/focus color and the background color have been added.

bll 2019-11-30: Version 7.0 splits out the theme specific data into separate files.

bll 2019-11-23: Version 6.0 adds the scalable winxpblue theme.

bll 2019-11-19: Version 5.0 features an additional scaling setting for use by the application, and the ability to create a scaled style, giving different graphics sizes for the same theme using the new style.

bll 2019-10-4: With version 4.0, support for other themes has been added. A scalable 'black' theme has been implemented.

bll 2019-10-7: With version 3.0, if tksvg is present, the graphics will scale according to the tk scaling setting.

bll 2018-9-1: Just thought I would try and create a new theme. Loosely based on adwaita dark. I have learned more about ttk themeing, found issues in my application code related to colors and themes. Uses graphics for the checkbuttons and radiobuttons. The notebook tab top color is created dynamically. Everything else is based on the clam theme.

 Application Scaling

In order to match the theme graphics size to the font size, the application can:

   tk scaling 1.3888 ; # set the tk scaling appropriate to the user's computer

   set sz1 [font metrics TkDefaultFont -ascent] ; # the default font size for Tk
   set sz2 [font metrics appfont -ascent]       ; # the application font default size
   set scale [expr {double(sz2)/double(sz1)}]   ; # calculate the scaling ratio
   package require awthemes
   ::themeutils::setThemeColors awdark \
       scale.factor $scale
   package require awdark 

 Demonstration: Scaled Styles

Same theme, different styles, different graphics sizes:

A new style with appropriately sized graphics can be created. For example, the application may have a base application font size used everywhere, and an alternate sized font for data listings.

The application can then:

  package require awdark
  if { [info commands ::ttk::theme::[ttk::style theme use]::scaledStyle] ne {} } {
    ::ttk::theme::[ttk::style theme use]::scaledStyle Listing mainfont listingfont

Then the data listings are created using Listing.TCheckbutton, Listing.TCombobox, etc. which match the font size specified.

All of the Listing.* widgets have re-configured graphics sizes to match the specified font.

::ttk::theme::awdark::setMenuColors .menuwidget

Sets the menu colors and also changes any checkbutton and radiobutton types to use thematic images. Run this after adding all the menu items to the menu.

Side effect: The menu will have -hidemargin set to true.

If you don't want the thematic images, run it before adding your menu items (and set -hidemargin back to false).

::ttk::theme::awdark::setTextColors .textwidget ?-dark?

Sets the text widget colors. If -dark is specified, the darker background color (as for entry) will be used.

::ttk::theme::awdark::setListboxColors .listboxwidget

Sets the listbox widget colors.

Jeff Smith 2020-06-29 : Below is an online demo using CloudTk. This demo runs awthemes in an Alpine Linux Docker Container. It is a 27.8MB image which is made up of Alpine Linux + tclkit + awthems-9.2.2.kit + libx11 + libxft + fontconfig + ttf-linux-libertine. It is run under a user account in the Container. The Container is restrictive with permissions for "Other" removed for "execute" and "read" for certain directories.

By clicking on the "V" in the upper left corner you can access other demos.
