RE: [libreoffice-accessibility] Re: ESC meeting minutes: 2022-05-26 [IAccessible2 support in JAWS]

Hi Michael,

JAWS does support IAccessible2, but only if it needs to, like in Firefox, and some parts of 
Chromium-based browsers. However, with the UI Automation implementation for the latter becoming 
stronger, there might be a time when JAWS moves to UIA for web content support in Chromium 
browsers. But you never know what plans Vispero actually has for which version of JAWS, ZoomText, 
and Fusion. All I notice is that, with Windows 11 having an even stronger UIA implementation than 
10, more things are being done through that interface rather than traditional MSAA or IAccessible2 
channels where possible. And as has been said elsewhere, UIA properties and events are even very 
accessible from within the JAWS scripting language, which makes this even more compelling because 
the end user experience can be customized further. As IAccessible2 is an extension of MSAA, and 
MSAA is largely deprecated by Microsoft, it will probably never get the same treatment.

That sounds promising, JAWS was what I vaguely had in mind about having been mentioned of 
presumably not supporting IAccessible2 (well) in the past.

Thanks a lot, that's much appreciated!
