Bug 23583 – Populate role attribute for Documents

• Component: Accessibility
• Status: RESOLVED FIXED

[Sankar Aditya Tanguturi]

When a page is loaded in safari and inspect32 tool is invoked, Accessibility role attribute for document is not properly populated. We need to add a new role i.e documentRole and need to set that role to all document objects.


~ Thanks
Sankar.

This is a very small patch. This patch just contains the changes to add a new accessibility role i.e. document for document objects and populate it correctly when focused.

This patch just creates a new accessibility role i.e. documentRole for document objects and populate that role appropriately when focused.

[chris fleizach]

is the document role in windows equivalent to a web area role in Mac?

[Jonas Klink]

Yes, this is also equivalent to ATK's role ATK_ROLE_DOCUMENT_FRAME.

[chris fleizach]

are you sure you need to add a DocumentRole then to the list of roles, since apparently DocumentRole is the same thing as WebAreaRole

[Jonas Klink]

As long as MSAA will return the correct role on Windows (ROLE_SYSTEM_DOCUMENT), either way works for me.

[Sankar Aditya Tanguturi]

This patch returns the appropriate MSAA role i.e. ROLE_SYSTEM_DOCUMENT on windows. I don't find anywhere in the code that returns this role for windows.

~ Thanks

Based on my reading of the code Chris is right and WebAreaRole already serves this purpose.  I think MSAARole simply needs updated to map WebAreaRole to ROLE_SYSTEM_DOCUMENT on Windows.

As mentioned in review comments, I have update the patch.

1. Just added changes to populate role attribute for documents objects correctly.
2. Added a new test case. This fix is specific for windows accessibility. So, moved the test case to LayoutTests/platform/win/accessiblity directory.

~ Thanks.

looks ok to me

I cleaned up the ChangeLogs some.  I also removed some extra spaces and HTML from the layout test.  I don't understand why the layout test needs to use an onload handler.  I woudl expect it to work inline.  But since I don't have a windows box to test on, I'm just going to leave it using the onload.

The test would really be better as a JS-style test (like those in fast/js) but it's fine for now. :)

I also made     virtual long role() const;
have "virtual" since we try to be explicit about what methods are virtual and what are not, even though the keyword is not strictly required for subclass implementations.
