382860 - No caret events in CSS scrollable area

Status: RESOLVED FIXED

(Core :: Disability Access APIs, defect)

Description

[Aaron Leventhal]

Attachment: CSS overflow testcase

Caret events are not being correctly fired in DOM nodes made accessible because they are scrollable (and thus need to be focusable so keyboard users can scroll them).

Load the attached testcase and turn on caret browsing. Caret move events will not be fired for the object.

Attachment: Use nsHyperTextAccessibleWrap (which inherits from nsAccessibleWrap) for generic HTML container accessibles instead of nsAccessibleWrap. It supports the caret and selection.

I guess it's ok to create hypertext accessible for all frames we have not enough info about. Though probably we should get rid CreateHTMLGenericAccessible at all, or is it better to keep it for possible future changes?

I filed bug 382966 for that cleanup -- we only need one of those methods.
