Description Scott Haeger 2007-11-05 13:16:46 PST
The tooltip seen here has the following debug for the Accessibility::Event object.  Note that the any_data field, the target of the object:children-changed:add event, is None. 

source =  [paragraph | ]
type = object:children-changed:add:system
any_data = None
detail1 = 2
detail2 = 0 

This is also the case for dojo tooltips (actually alerts) seen here and the tooltips linked from .

A strange oddity is that object:children-changed:add events for the live region examples were broken (pre-pyatspi migration for Orca) with respect to user_data, but now they work.  Beyond event type, I am not sure how else the two issues are related.
Comment 1 Scott Haeger 2007-11-06 06:30:41 PST
Accessibility::Event.any_data is correct if you change the 'span' to a 'p' for the tooltip in .  Please fix span issue (tough one I'm sure) or change the example, possibly mentioning <span> unsupported.

Now investigating why UIUC and dojo examples are unsupported with regard to any_data.
Comment 3 Scott Haeger 2007-11-06 07:15:06 PST
The dojo example seen here also uses a span for the tooltip.  However, changing it to a <p> did not fix the problem.  I tried several markup changes to the surrounding tooltip markup, all with no luck.  The event.any_data field is always None for object:children-changed:add:system events.  Also of note is that the object:text-changed:inserted:system events appear to be of little worth to Orca for tooltip announcements.

Comment 5 Scott Haeger 2007-11-27 08:36:07 PST
The UIUC tooltip examples can be fixed by changing their hiding/showing logic to use display:[none|inline] instead of moving the tooltip way off the screen.
Comment 6 Ginn Chen 2008-01-29 02:16:38 PST
We should not use
in  nsAccessibleWrap::FireAtkShowHideEvent

because for ATK we don't want to include text leaf nodes as children.

Nice work Ginn! I bet this solves a lot of other issues with show/hide events!

This bug and it's sister bug #402049 are both looking much better.
