From f6498fd6776b08b6bd33395e3f716b6d5d79a8b8 Mon Sep 17 00:00:00 2001 From: Marc Mutz Date: Fri, 30 Sep 2016 22:21:37 +0200 Subject: Plug more than 4k leaks in tst_QGraphicsView The vast majority is due to leaking styles in a data-driven test with almost 100 rows (scrollBarRanges()). Fix by creating the style into a QScopedPointer. The remaining ~500 leaks were due to leaked QGraphicsScenes. They had no parent, and QGraphicsView::addScene() does not adopt them. Fix those by passing the resp. view as their (QObject) parent.
