217311 - [ATK Accessibility] wrong text structure for HTML text

Status: RESOLVED FIXED

(Core :: Disability Access APIs, defect)

Description

[Kyle Yuan]

Currently, we are using block frame to generate the accessible text object for 
ATK. This will be failed in many cases which include a block frame with a 
nested block frame.
The new algorithm should be able to organize the text frame as much as possible 
within a same block frame and should not cross other block frame's boundary.

Attachment: the patch

1) rewrite the algorithm of generating text block (big work) - the previous
sucks;
2) fix a bug in nsOuterDocAccessible - the mFirstChind sometimes broken;
3) change the role of nsXULTabPanelsAccessible from ROLE_PROPERTYPAGE to
ROLE_PANE;
4) change the role of nsOuterDocAccessible from ROLE_CLIENT to ROLE_PANE;
