1644810 - Tree views don't talk well with VoiceOver

Status: VERIFIED FIXED

(Core :: Disability Access APIs, defect, P1)

Description

[Marco Zehe (:MarcoZ)]

Steps, with VoiceOver on:

1. Visit this example tree view.
2. Tab to the actual tree view.
   • Firefox: Claims the table is empty, and seems unsure where the focus is.
   • Safari: Recognizes the table, and speaks where the focus is.
3. Start arrowing through the tree with up and down arrows.
   • Firefox: Speaks "List box", followed by the item.
   • Safari: Speaks "Listbox" and the item, but also the level, and if it is collapsed.
4. On an expandable item, press RightArrow to expand:
   • Firefox: Just repeats the item, does notgive an indication that the tree item has expanded.
   • Safari: Indicates that the item has expanded.
5. DownArrow into the newly expanded items.
   • Firefox: Only says "listbox" and the item.
   • Safari: Gives an indication of the level change.

Note that Safari and VoiceOver are a bit inconsistent about announcing the level changes when items are already expanded, and one traverses from a level 1 node to a level 2 one, or vice versa. But Firefox and VoiceOver don't give an indication at all.

The tree view inconsistencies are also reproducible using the HTML Inspector developer tool.
