Re: [g-a-devel] Extensible states (or properties)



Screenshot for Thunderbird.

Notice that the Message -> Label submenu shows how to mark these. In fact you can just hit 0-6 to mark the message. Each is represented by a different color.

Doesn't seem like something can be both Work and Important :)

Where is the color? It is overlaid on the text, or is there a cell in a column that contains a color? If the latter, then that cell object can convey this information. Perhaps you can post a screen shot?

For the IM example, away is indicated with a color. The status string is not rendered unless you hover over the buddy name.

Ah. So it is rendered in this case like a tooltip? We typically map AccessibleDescription to tooltips.

Again, a screen shot would be helpful.

How would you recommend exposing these today?

Hi Aaron,

I don't understand why these need to be ATK states. In the e-mail case you cite, "Junk" and "Flagged for follow up", etc. are either written as text on the screen, or there is an icon that can have an AccessibleName. This is, after all, how the sighted user gets the information.

In the IM client, your status string example speaks for itself - it is a string. It should implement Atk_Text of course.

In the calendar, how is this information indicated to the user? Via icons or text, right? Again, we have standard ways to convey icon information, and of course text.

While these things are, semantically, "state" things, they are about the state of the application (IM), or of a record in the application (e-mail, calendar), and are already otherwise conveyed using user interface elements that we otherwise would be making accessible.


These don't seem like reasons to add new states to me, let alone something that needs to completely change the state mechanism (to allow for arbitrary strings).

One thing that has come out in the working group for DHTML accessibility is the need for extensible states.

Some sample use cases:

_Email:
_An email message may be marked with states such as "Junk", "Flagged for follow up", "Unread"

_IM client:_
A buddy in a buddy list can have one of the states: idle, away, do not disturb, etc. These may not be boolean as there may be a status string such as "Idle for 33 minutes" or "Away: at lunch"

_Calendar:
_A schedule item make have a state: conflicting, repeating, tentative, etc.

We can try to expand the states table to contain all of these use cases, but I don't think we can ever name all of the useful potential states or properties. At the moment people stuff this information into a tooltip or accessible name, which isn't a good long term solution. UI Automation will provide a localized statusString which will provide this info, but that is not semantic -- it would not allow the toggling of these states via on onscreen keyboard. On the other hand, it is a practical, simple solution which gets most of what's needed.

What will ATK provide?
