From: Robin Burchell Date: Fri, 2 Aug 2013 22:27:40 +0000 (+0200) Subject: Implement resource policy plugin using libresourceqt. X-Git-Tag: upstream/5.2.95+rc1~52^2~10 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=9f484eae83fd81e12aa4f07398ad13f9d453ba92;p=platform%2Fupstream%2Fqtmultimedia.git Implement resource policy plugin using libresourceqt. This contains a new resource policy plugin, replacing the built-in code that was deleted when the plugin interface was removed in 138242fb2dc19438a0ead34b36af848800e27190 (which unfortunately did not provide a plugin).
