Subject: [Accessibility-atspi] adding ScrollTo to at-spi?
Message-ID: <20180123111541.i3534ncr6e45ft7m@var.youpi.perso.aquilenet.fr>

Hello,

While working on accessibility of firefox, we have found that when
continuously reading a web page, the page gets scrolled automatically
only line by line. On windows, NVDA gets firefox to scroll paragraph by
paragraph, which makes reading nicer. More generally, AT technologies
such as magnifiers etc. could have a use for a primitive to tell
application how scrolling should behave.

On windows, IA2 provides ScrollTo RPCs
http://accessibility.linuxfoundation.org/a11yspecs/ia2/docs/html/interface_i_accessible2.html#afd79074abd176643d560444058da55fc
which allows the screen reader to act on application scrolling: bring
some object to the top or bottom of the screen, at some specific
location, etc.  This is what allows NVDA to get firefox to scroll
paragraph by paragraph.

I'm wondering whether adding this to AT-SPI could be considered?

I have reported this question to https://bugzilla.gnome.org/show_bug.cgi?id=792820
