Support for Orca's global structural navigation

[RastislavKish]

Hello,

In commit 1a10f8c5c of https://gitlab.gnome.org/GNOME/orca, Orca starts the work on supporting global structural navigation, which should bring a web-like experience to all apps, allowing more convenient, structural access to their content, improving on focus handling issues and allowing quick navigation in document styled interfaces.

The new functionality requires toolkits to implement the Atspi Collection interface for relevant components in order to provide structural navigation. I have tested eframe 0.32 with egui 0.32 and accesskit 0.17.1. It seems these interfaces are not supported yet.

could AccessKit implement the support for Atspi Collection?

Thanks for the great work!

Hello @RastislavKish,

Indeed the Collection interface is not yet supported. It previously was mostly a way to optimize queries of the accessibility tree so it wasn't a priority for me. Now if Orca starts using it for something useful, this obviously increase its importance.

Implementing it was already on my list of things to do, but thank you for bringing this to our attention. I'll re-evaluate the priority.
