tab, tabpanel and tablist
tab needs to support AXValue (whether its selected... which can be either if an item in its associated tab panel has focus, or it has aria-selected) a tab can also be selected if KB focus is in one of its aria-controls elements tablist needs to support AXValue = selected tab, AXContents (children that are not tabs) and AXTabs (children that are tabs) tabpanel needs to be an AXGroup with a subrole, like the other aria landmarks make sure this works http://codetalks.org/source/widgets/tabpanel/tabpanel1.html
Created attachment 42300 [details] patch Beth, I've made these tab roles like we talked about tab = AXRadioButton tablist = AXTabGroup tabpanel = AXGroup:AXTabPanel I also mirrored the other Mac accessibility things relating to tabs, and tried to follow ARIA spec. I re-organized some code so that it would be easy to get all Elements from a specific attribute. As a note, when i ran update-webkit-strings, it removed two accessibility strings. i guess those are no longer used...
Beth, can you review this one. One of the ARIA things we talked about
