What is `at-spi2-atk`

at-spi allows assistive technologies to access GTK-based applications. Essentially it exposes the internals of applications for automation, so tools such as screen readers, magnifiers, or even scripting interfaces can query and interact with GUI controls. This version of at-spi is a major break from previous versions. It has been completely rewritten to use D-Bus rather than ORBIT / CORBA for its transport protocol. This package includes a gtk-module that bridges ATK to the new D-Bus based at-spi. at-spi2-atk 2.26.2 1.el8 x86_64 89 k at-spi2-atk-2.26.2-1.el8.src.rpm appstream A GTK+ module that bridges ATK to D-Bus at-spi https LGPLv2+ at-spi allows assistive technologies to access GTK-based applications.
