Public bug reported:
As text in notification bubbles are fairly dynamic, an atk text
interface will help assistive technologies distinguish between replaces
and appends. There should also be as much support for advanced text
features as possible.
Here is a list of interface methods, and the feasibility of having them
given the current limitations in the bubble rendering code:
Accessibility::Text::getText
Accessibility::Text::getCharacterAtOffset
These should be easy to implement, simply get the bubble's body contents.
Accessibility::Text::getTextAfterOffset,
Accessibility::Text::getTextAtOffset,
Accessibility::Text::getTextBeforeOffset
These will be problematic to implement fully, specifically because it requires
knowledge of line boundaries.
Accessibility::Text::removeSelection
Accessibility::Text::setCaretOffset
Accessibility::Text::setSelection
Accessibility::Text::getSelection
Accessibility::Text::addSelection
These simply should return false or zero values since the bubble is not
editable, selectable or caret navigable.
Accessibility::Text::getCharacterExtents
Accessibility::Text::getRangeExtents
Accessibility::Text::getOffsetAtPoint
Accessibility::Text::getBoundedRanges
These will be problematic to implement since the text rendering is flat - no
extents information is stored after the bubble is rendered.
Accessibility::Text::getAttributeValue
Accessibility::Text::getAttributes
Accessibility::Text::getAttributeRun
Should be possible to implement. The good news is that there is only one
"attribute run" since the bubble's body does not support markup. The bad news
is that we will probably need to retrieve the information directly from
defaults.c, or whatever config backend we use, since the bubble does not store
enough text attribute info itself.
