AX: Add ability to specify descendant type when using AXUIElementsForSearchPredicate.

• Component: Accessibility
• Status: RESOLVED FIXED

[Samuel White]

Add the ability to limit element results to immediate container descendants only.

This can be accomplished by supporting the following new keys and values:

Key:
AXImmediateDescendantsOnly (similar to AXVisibleOnly)

Value:
YES/NO

Unless we suspect further descendant filtering needs will arise in the future. In which case we could start with:

Key:
AXSearchScope (similar to AXSearchText and AXSearchKey)

Values:
AXAllDescendants
AXImmediateDescendants

Patch.

Updated log comment per review and fixed layout test expectations.

I'm going to let this one go in even though the mac WK2 bot looks flaky (I'll keep an eye on it and rollout if it is indeed an issue). Reason being, I'm seeing these same flaky issues in other patches that have already landed (watching the console). For example https://bugs.webkit.org/show_bug.cgi?id=128792 looks to have similar flaky test issues on mac-wk2. So, I suspect these are not related to this patch. Also, this patch doesn't make any changes to areas that are being flaky.

Patch.

I'm going to rebase this one and run it through EWS again.

Rebased patch.

Rebased because the commit bot was having trouble applying this one. Turns out it made no difference. Still, sending through EWS again to be double sure we aren't adding to the recent bout of test flakiness.

[Samuel White]

Same patch, just rebased. Chris, could you + this one again and I'll commit manually if everything looks good and the commit bot is still having issues. Thanks.
