> I wonder what ever happened to the Newton accessibility bus intended to supplement Wayland...

Hm, never heard about it, but now I'm wondering too. I just finished implementing proper accessibility support for my native app toolkit for Linux, macOS and Windows, but only done it for X11 so far, I was just gonna get started with Wayland. What is the accessibility story on Wayland, couldn't people rely on the same protocols as with X11? That was my impression, but haven't really dig into yet.

It's still AT-SPI for wayland, the main difference is how screen readers grab keyboard input events.[0] I don't think there is a big difference from a toolkit point of view. I don't personally have experience with Wayland because most blind people recommend Mate as being the most accessible desktop still.

Thanks for considering a11y for your toolkit - it really makes a difference to those of us who are disabled. Are you implementing a11y separately for each platform? If you use accesskit[1] you only have to implement it once for all platforms. I recently vibe coded accessibility for the Swell toolkit[2] used by Reaper. I have a branch using accesskit and a branch implementing at-spi. Accesskit made things a lot easier and more performant.

Let me know if you would like a screen reader user to help with testing your toolkit.
