As the guy working on accessibility support for WebKitGTK+, I attended the hackfest to join some other great people representing different projects, such as Mozilla, Orca, AT-SPI, ATK, GTK+ and Qt. So, apart from helping with some “local” organizational details of the hackfest and taking some pictures, I spent some time hacking in WebKitGTK+‘s accessibility code and participating in some discussions.
And from that dedication I managed to achieve some interesting things too, being my favorite ones a big refactoring of the a11y code in WebCore (so it’s now better organized and hence more readable and easy to hack on) and pushing my patch for enabling accessibility support in WebKit2GTK+, after going through a meticulous process of review (see the related WK bug), which started with the patch I wrote and attached back when attending to the WebKitGTK+ hackfest, as I mentioned in my previous entry in this blog.
Yeah, I know that some weeks have already passed since then and so perhaps you’re thinking this could have been done faster… but I’ve spent some weeks on holidays in Barcelona in December (pictures here!) and so I wouldn’t have much time before January to devote to this task. However, the patch got integrated faster than what I would expect when I proposed the first version of it, so I’m quite satisfied and happy anyway just by being able to announce this at this moment. Hope you share my joy
So, what does this mean from the point of view of accessibility in GNOME? Well, that’s an easy question to answer: from now on, every browser that uses WebKit2GTK+ will be as much accessible as those using the previous version of WebKitGTK+, and this is definitely a good thing. Of course, I’m certain there will be bugs in this specific part that will need fixing (as it always happens), but for the time being this achievement means “yet another thing less” preventing us from pushing for upgrading some applications to switch to WebKit2GTK+, such as devhelp (some ongoing work already done, as my mate Carlos announced yesterday), yelp, liferea… and the mighty Epiphany browser, which is rocking more and more ech day that goes by.
Last, I’d like to share with you an screenshot showing this new stuff, but as I am a little bit tired of always using Minibrowser (that small browser we use for testing WebKit2), so I decided to try instead that new branch Carlos recently pushed for devhelp, so you could check that what I mentioned before is actually true.
So here you have it (along with a couple of additions done with Gimp):
As you can see, devhelp is running and Accerciser is showing the full hierarchy of accessible objects associated to the application, starting in the UI process (GTK+ world) and continuing in the Web process, where all the accessible objects from the WebKitGTK+ world are being exposed. As I explained in a previous post, the magic making possible the connection between the two process is done by means of the AtkSocket and the AtkPlug classes, also represented in the screenshot attached above.
So, that’s it.
