Priority: medium
Bug ID: 75151
Assignee: [email protected]
Summary: [Win Accessibility] AccDescription has disappeared
from most controls
Severity: major
Classification: Unclassified
OS: Windows (All)
Reporter: [email protected]
Hardware: Other
Status: UNCONFIRMED
Version: 4.3.0.0.alpha0+ Master
Component: UI
Product: LibreOffice
In current Master builds, the Acc_description has disappeared from most
standard controls such as Buttons, Checkboxes, Radio Buttons etc.
To compare:
1. Open LibreOffice 4.2.0. Focus lands on the Open File button.
Using NVDA, I press Insert+F1 and get this information:
Developer info for navigator object:
name: u'Open File'
role: ROLE_BUTTON
states: STATE_FOCUSABLE, STATE_FOCUSED
isFocusable: True
hasFocus: True
Python object: <NVDAObjects.Dynamic_SymphonyTextButtonIAccessible object at

dialog.'
IAccessible accValue: None
IAccessible2 windowHandle: 525122
IAccessible2 uniqueID: -66
IAccessible2 role: ROLE_SYSTEM_PUSHBUTTON
IAccessible2 states: (0)
IAccessible2 attributes: exception: (-2147467259, 'Unspecified error', (None,
None, None, 0, None))
The important line is:
IAccessible accDescription: u'The Open a Document icon presents a file open
dialog.'
2. Now, open a current LibreOffice 4.3.0 dev build, any build from recent
couple of days will do. The info looks almost identical for the same button,
except:
IAccessible accDescription: u''
3. Back in LibreOffice 4.2, open any Writer document, then go to File/Export as
PDF. All of the controls have explanatory descriptions, for example the "Tagged
PDF checkbox":
Developer info for navigator object:
name: u'Tagged PDF'
role: ROLE_CHECKBOX
states: STATE_CHECKED, STATE_FOCUSABLE, STATE_FOCUSED
isFocusable: True
hasFocus: True
Python object: <appModules.soffice.SymphonyText object at 0x057EBA50>

STATE_SYSTEM_FOCUSABLE, STATE_SYSTEM_VALID (1048596)
IAccessible accDescription: u'Selects to write PDF tags. This can increase file

IAccessible accValue: None
IAccessible2 windowHandle: 853040
IAccessible2 uniqueID: -673
IAccessible2 role: ROLE_SYSTEM_CHECKBUTTON
IAccessible2 states: (0)
IAccessible2 attributes: exception: (-2147467259, 'Unspecified error', (None,
None, None, 0, None))
4. Performing the same in the LibreOffice-dev 4.3 build, I again get:
IAccessible accDescription: u''
This feels like some more general breakage to me. Note that this does not
affect all descriptions. For example tables and table cells in Writer documents
still expose the correct accessible description.
