To all interested in scalability of the widgets in Tk 8.7: I have just
filed a ticket regarding the ttk::checkbutton and ttk::radiobutton
indicators of the clam theme. See

https://core.tcl-lang.org/tk/tktview/fecc86e5e0

I would welcome any comments in this newsgroup or on the ticket page.

As mentioned in that ticket, the indicators of the ttk::checkbutton and
ttk::radiobutton widgets of the clam theme don't look really good,
especially on a scaled screen, as shown in the screenshot

https://core.tcl-lang.org/tk/artifact/03910bf53627cc03

The ticket proposes to replace the C code responsible for drawing these
indicators with one using SVG-images, in order to get really
professional-looking and properly scaling indicators, as shown in the
screenshot

https://core.tcl-lang.org/tk/artifact/b3e191fe1c300b7b

The new implementation is completed and fully tested. The question is:

*Should it be incorporated in Tk 8.7b1, which will be released soon? *

I would highly appreciate to hear your opinion regarding this subject.
Many thanks in advance for your feedback!

I've used the Clam theme for years, but have always avoided using its radiobuttons and checkbuttons, because of the reasons stated in Csaba's comments. This is a huge improvement to the theme and I'm hopeful that it will get implemented asap!

since this is not a change in functionality, but "only" the looks, and
it is a massive improvement especially for high resolution screens, I
would rather consider it as a bugfix, and therefore can and should be
integrated any time soon.

Definitely YES.

Yes, definitely!

How about regular checkbutton and radiobutton widgets? Are they covered
as well?

Yes, in Tk built from trunk the Tk core checkbutton and radiobutton
widgets on both X11 and Windows are scaling-aware too, meaning that they
will be scaled automatically, according to the display's DPI scaling
level. The C code for X11 was joint work by Brian Griffin and myself.

Many thanks to all who have posted their comments! Motivated by the
positive feedback, I have merged the code into trunk and have closed the
ticket with the resolution "Fixed". Let's hope to see the Tk 8.7b1
release within the next few weeks!
