132158 - Active Accessiblity: Report proper bounds for Image map areas

Status: RESOLVED FIXED

(Core :: XUL, defect, P5)

Description

[John Gaunt (redfive)]

Currently when focused by tabbing or walking through the image map using the
MSAA Inspector the bounds of individual areas is not reported correctly. This
results in the ring being drawn by MSAA Inspector in the upper left corner.

I'm not going to prioritize this very high, because the screen reader vendors
have not asked for it yet. I think we should do it eventually, however.

There is some lacuna in image map. Maybe the bug 135040 is valuable for this bug.

Comment 3

[Aaron Leventhal]

Gilbert, I'm sorry I don't fully understand your comments in bug 135040. I am
the wrong person to answer questions about the primary frame map.

I was saying that GetPrimaryFrameFor for an image map area should return the
image map area frame. I agree that GetPrimaryFrameFor for the who map node
should return the image.

In any case, we obviously need some way to get the bounds of the map area.

oh, maybe I did not express myself clearly because I had not master the key part
of these two bugs. I will work more deeply .

I have a patch for this. It also fixes accessible value to be the expanded href
of an area. The accessible name uses the title if it exists, otherwise the href.

This is slightly different from IE, which doesn't use the title at all. I think
we should use the title - it seems too useful to pass up.

Seeking r= from Beijing team.
