[WK2][GTK] Implement AccessibilityUIElement in WKTR for GTK

• Component: Accessibility
• Status: RESOLVED FIXED

[Mario Sanchez Prada]

At the moment, WebKitTestRunner's implementation of AccessibilityUIElement is only available for the mac.

Thus, we need to provide an implementation for GTK if we want to be able to run the layout tests in WebKit2GTK+ (which we want). The idea would be to implement at least the same features we have in DRT's implementation of AccessibilityUIElement, so we can pass the same tests we already pass for WK1.

The idea with this patch is to provide basic support for accessibility in GTK to WKTR, and it certainly does that, since almost 100 a11y tests are now passing...

However, some others are not passing yet and some are even crashing. Those will be addressed later in separate bugs.

Ooops! Sorry, this is the right one (some tests to be skipped missing in the previous patch)

New patch. Implementing AccessibilityUIElements using AtkValue interface in a better way (see Martin's comments for bug 89226) and adding two more tests that are randomly crashing to the Skipped file.

looks good. a few minor nits

seems like you could probably implement this method pretty easily

extra white space after = sign

two FIXME's here

Thanks Chris for reviewing this, just got back from holidays today, so please understand my late reply.

Indeed. I just haven't done it so since I was more worried at this point about porting DRT stuff to WKTR rather than adding new stuff.

Still, I agree implementation for this one is very simple, so I just added it.

For some reason check-webkit-style didn't get this one. Thanks for pointing it out.
