346906 - Hypertext::getLinkIndex return value is one off

Status: RESOLVED FIXED

(Core :: Disability Access APIs, defect)

Description

[parente]

The value returned by getLinkIndex appears to be off by one.

1) Visit http://www.mozilla.org/access/unix/new-atk.html
2) Inspect the html container accessible using at-poke or a similar tool.
3) Notice the first four characters in its accessible text are embed characters.
4) Call Hypertext::getLinkIndex(0) for the first embed character.
5) Note that the at-spi return value is -1. The correct result should be 0.
4) Call Hypertext::getLinkIndex(1) for the second embed character.
6) Note that the at-spi return value is 0. The correct result should be 1.

The complete result of using getLinkIndex for the first four embed characters and the first non-embed character is the following:

char offset: 0  link index: -1
char offset: 1  link index: 0
char offset: 2  link index: 1
char offset: 3  link index: 2
char offset: 4  link index: -1
