Subject: atspi: support "default_label" attribute of window
X-Git-Tag: accepted/tizen/4.0/unified/20171012.225849~9
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=9d5594a3afd63368a7876cf54f191fbdc039bbfc;p=platform%2Fupstream%2Felementary.git

atspi: support "default_label" attribute of window

Wearable profile application does not want to use default label functionality
because it is hard to meet application UI definition.
So if the window has attribute "default_label" key, and its "disabled" value,
then screen-reader does not read out default label, and does not clear
currently highlight object.

Application should append attribute as below.

elm_atspi_accessible_attribute_append(window, "default_label", "disabled");

This patch set works with following patch set.
