From 253b87180e0a6c5db0feaaed7e321139c4ff1643 Mon Sep 17 00:00:00 2001 From: Gabriel de Dietrich Date: Tue, 6 Apr 2010 17:04:20 +0200 Subject: Moved item wouldn't follow mouse cursor when ItemIgnoresTransformations is set Since the introduction of transform properties in QGraphicsItem, QGraphicsItem::transform() is no longer enough to get the correct transform of an item. No auto-test as it involves mouse dragging.
