From 6a1cff7c47e1f47161f765ba2f7094b55aaa13c5 Mon Sep 17 00:00:00 2001 From: Yoann Lopes Date: Fri, 11 Dec 2009 16:41:00 +0100 Subject: Fixes Graphicsitem transformation problems when grouping/ungrouping. New transformation properties added in 4.6, such as rotation or transformOriginPoint were not taken into account in addTogroup and removeFromGroup. Autotest and manual test included.
