Bug 326092

Description Rich Schwerdtfeger 2010-09-23 15:24:16 EDT

Build Identifier: 

This was originally fixed in defect 131958. Since then the WAI-ARIA specification changed such that it no longer uses namespaces. Consequently, ARIA semantics are not recognized, not mapped to accessibility APIs, and not spoken by screen readers.

What I believe the change is that needs to be made is:

So, the namespaces go. role attributes and their values are no longer namespaced. ARIA states and properties become aria- followed by the value.

x2:role="wairole:tree" 

becomes

role="tree"

and

waistate:expanded="true"

becomes aria-expanded="true"

so, 

where you have 

That would change this snippet:


<div x2:role="wairole:tree" tabindex="-1" class="tree"
onclick="return treeItemClick(event);"
ondblclick="return treeItemEvent(event);"
onkeydown="return treeItemEvent(event);"
onkeypress="return treeItemEvent(event);" id="tree">
<div id="veggieDiv"><img src="minus.gif" tabindex="-1"
x2:role="wairole:presentation" onclick="imgToggle(event);" alt=""><span
tabindex="0" x2:role="wairole:treeitem" waistate:expanded="true"

To:

<div role="tree" tabindex="-1" class="tree"
onclick="return treeItemClick(event);"
ondblclick="return treeItemEvent(event);"
onkeydown="return treeItemEvent(event);"
onkeypress="return treeItemEvent(event);" id="tree">
<div id="veggieDiv"><img src="minus.gif" tabindex="-1"
role="presentation" onclick="imgToggle(event);" alt=""><span
tabindex="0" role="treeitem" aria-expanded="true"

Here are some examples:

It is important that we keep the structure (tree, treeitem, groups, etc.)


Reproducible: Always

Steps to Reproduce:
1. simply bring up eclipse help
2. Start the JAWS screen reader
3. navigate to the navigation panel (tree widget) and navigate it with the keyboard.
4. You will not be able to use the arrow keys to navigate the navigate the navigation tree folders on the left hand side of the help screen and JAWS will not read them. If you tab between tree items JAWS will call them links
4. If it is fixed JAWS will not steal the keyboard keys used to open and close folders and you will hear the tree items or folders and their expanded/collapsed state as well as folder depth information along with the number of elements at that level.
5. without this blind computer users cannot access Eclipse help
