Fix focus render on AccentButton

[oldium]

The AccentButton has no focus frame when navigated with Tab key, so fix this.

Unfortunately neither of the other widgets has focus indicator, but thanks for adding it to the button anyway!

Maybe off-topic. The Tk project has recently worked on the focus ring code: Tk commit 2b72403febce58be.

Great work, rdbene,

Ahh, nice. Thank you Harald for letting me know!

Have you seen the scaling presentation by Csaba at the Vienna OpenACS/TCL/Tk conference ?

It will be again in early summer in Vienna in 2024 ;-).

Thank you,

Thanks for the links!
I haven't seen it yet, but I was aware of it for quite a while. It might come useful, as currently I'm in the process of porting the Sun Valley theme to use SVG image.

Yes, great !
You might be interested in Csabas work on scaling on tablelist/scrollutil on nemeti.de.
And my favorite are the AWThemes, which are fully scalable, but unfortunately unmaintained.
The author has worked a lot on performance.

There is a nasty bug in Tk about image performance in the moment there is transparency involved, and since years no person fixing it...
