From f0ce8b847e2169ad4ae884dbb35b58e6dd0f1859 Mon Sep 17 00:00:00 2001 From: J-P Nurmi Date: Tue, 24 Jan 2017 15:29:07 +0100 Subject: tst_snippets: share a single QQuickView instance for all data rows This test contains a lot of data rows. Re-creating a QQuickView for every data row puts a lot of stress on the system. In the new Open Nebula -based CI, things start consistently exploding after a random amount of tst_snippets data rows. This change fixes that.

At that point the QQuickApplicationWindow object for the member function _q_updateActiveFocus() was already destroyed, so we would crash. Instead, make sure we clear the focus as early as possible, and then disconnect in case activeFocusItemChanged() is emitted after QQuickApplicationWindow is destroyed.
