Subject: [PATCH v3 5/6] kernel-shark-qt: Make the Vis. model use Data collections.
Date: Fri, 3 Aug 2018 17:29:36 +0300 [thread overview]
Message-ID: <20180803142937.3970-6-y.karadz@gmail.com> (raw)
In-Reply-To: <20180803142937.3970-1-y.karadz@gmail.com>
This patch optimizes the search instruments of the model by
adding the possibility of using Data collections.
