As I said, those are long term tasks, and the fact is that the current accessibility status needs to be improved also in the short and medium term. I also planned to define those short-medium tasks, but after reading again some mails, Matthias already did it in this mail [3], so I will not repeat that. I will just include that as task 1.5 I would include refactoring gailtreeview, one of the big problems related to performance that prevents having a11y enabled as default [5] For making things work better in the short/medium term (ie before we land a complete refactoring/rewrite of gail), I think two things are essential: 1. Define the atk interfaces to a testable level. One example that I have run in recently is the 'name' property of AtkObject - it is not really defined at all what this is supposed to contain, and how it is supposed to be used. It turns out a change that I committed last September made menu accessibles not have names - it turns out that that breaks ATs which expected those names to be taken out of the labels contained in the menuitems. This needs to be specified somewhere, so that we can then 2. Test that the accessible implementations actually follow that spec. I want to be able to have a unit test in the GTK+ repository that instantiates a widget, gets the corresponding accessible, and then verifies that it has the expected properties. If we had such testcases, it would not have taken 9 months from me committing the breaking change to me committing the fix. On the other hand, the fact that nobody filed a bug maybe tells us something about the amount of real-life usage that the gnome3 accessibility stack currently gets... ___ gtk-devel-list mailing list gtk-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-devel-list
Re: www.gtk.org now updated but no news!
I have hopefully fixed this problem (I can't test with older versions of PHP, but I have tested the new function by itself, and in theory it will work.) Patch is located here: https://bugzilla.gnome.org/show_bug.cgi?id=651807 I also cleaned up some code used during development of the website. ___ gtk-devel-list mailing list gtk-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-devel-list
