From 63fdbf4633552126197fad0d5f0595d505a28164 Mon Sep 17 00:00:00 2001 From: Arnold Konrad Date: Fri, 8 Apr 2011 15:00:11 +0200 Subject: [QTBUG-15278] QWidget::windowState gets out of sync (Aero Snap) Windows 7 sends WM_SIZE messages without preceding WM_SYSCOMMAND when a window is maximized or restored via Aero Snap. These messages are now handled correctly.
