Hi,
I would like you to review the following patch:
https://gerrit.libreoffice.org/5160
To pull it, you can do:
git pull ssh://gerrit.libreoffice.org:29418/dev-tools refs/changes/60/5160/1
Add NSAXSpy to help debugging OS X accessibility
This tool currently logs the AXAttributedString of the first AXTextArea
found in LibreOffice (suited for Writer), and logs all AXValueChanged
and AXSelectedTextChanged notifications of that AXTextArea and also all
AXFocusedUIElementChange notifications. It can be adjusted to do
the same thing for TextEdit so that one can learn from it
how stuff should be implemented (TextEdit is basically
*the* reference implementation of AXTextArea).
Any adjustments (e.g. to observe TextEdit instead of LibreOffice)
need to be done in the source code of this tool.
