Accessibility Toolkit

<h2 id="implementations">Implementations</h2> <p>The ATK abstract <a href="/facts/Header_file/fg3KEG4V">headers files</a> are freely available to help developers who want to make their <a href="/facts/GUI_toolkit/v8wM8wwy">GUI toolkit</a> accessible.<a class="footnote-ref" id="fnref:2" href="#fn:2"><sup>2</sup></a> Developers who use stock <a href="/facts/GUI_widget/SuVeScB2">widgets</a> of GUI toolkits that implements the ATK headers can more easily make their applications accessible. However, if they develop their own widgets, they will have to ensure that they are exposing all the accessible information. </p><p>GAIL (GNOME Accessibility Implementation Library) was the name of the accessibility interfaces implementation defined by ATK for <a href="/facts/GTK%252B/oLpVm9pp">GTK+</a>, the widget library of GNOME. Initially, GAIL was an independent module mapped to GTK+ but since GNOME 3.2, GAIL was merged into GTK+, so the ATK implementation is integrated into GTK+ and GAIL is deprecated.<a class="footnote-ref" id="fnref:3" href="#fn:3"><sup>3</sup></a> </p><p>Apart from GTK+, other GUI toolkits and applications have implemented ATK in order to be accessible, such as OpenOffice<a class="footnote-ref" id="fnref:4" href="#fn:4"><sup>4</sup></a>/<a href="/facts/LibreOffice/MInj5kF7">LibreOffice</a>,<a class="footnote-ref" id="fnref:5" href="#fn:5"><sup>5</sup></a> Mozilla's Gecko,<a class="footnote-ref" id="fnref:6" href="#fn:6"><sup>6</sup></a> Clutter<a class="footnote-ref" id="fnref:7" href="#fn:7"><sup>7</sup></a> and WebKitGTK+.<a class="footnote-ref" id="fnref:8" href="#fn:8"><sup>8</sup></a> </p> <h2 id="development">Development</h2> <p>ATK is part of the GNOME Accessibility Framework that was released in 2001.<a class="footnote-ref" id="fnref:9" href="#fn:9"><sup>9</sup></a> The main development force behind ATK was the Accessibility Program Office (APO) of <a href="/facts/Sun_Microsystems/VJ9EzEFd">Sun Microsystems</a>, Inc. (now <a href="/facts/Oracle_Corporation/0z14FygH">Oracle</a>) with contributions from many community members. When Oracle acquired Sun in 2010 they cut developer jobs of full-time developers working on GNOME accessibility components such as the Accessibility Toolkit ATK and the Orca screen reader.<a class="footnote-ref" id="fnref:10" href="#fn:10"><sup>10</sup></a> Since then, ATK is mainly maintained by the GNOME community. </p> <h2 id="successor">Successor</h2> <p>During <a href="/facts/GUADEC/rx8G4sHc">GUADEC</a> 2020 Emanuelle Bassi announced to have been working for about 6 months on a successor to ATK.<a class="footnote-ref" id="fnref:11" href="#fn:11"><sup>11</sup></a> Accessibility will no longer be maintained out-of-tree but be part of <a href="/facts/GTK/oLpVm9pp">GTK</a>.
