From 86b4e19ee160ee3e84210595db5e6af08a8b9e46 Mon Sep 17 00:00:00 2001 From: Miikka Heikkinen Date: Thu, 27 Feb 2014 11:23:17 +0200 Subject: Introduce state storing for mac and android. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit At least some mac and android environments do not handle shared contexts properly, leading to slowdowns and/or artifacts. Disable context sharing on mac and android, and instead store and restore relevant opengl state. Also improve renderer and context cleanup Change-Id: I8fa596b95f6ff20d53c950a34b5c28513acbc18f Reviewed-by: Tomi Korpipää --- src/datavisualizationqml2/glstatestore_p.h | 99 ++++++++++++++++++++++++++++++ 1 file changed, 99 insertions(+) create mode 100644 src/datavisualizationqml2/glstatestore_p.h (limited to 'src/datavisualizationqml2/glstatestore_p.h') diff --git a/src/datavisualizationqml2/glstatestore_p.h b/src/datavisualizationqml2/glstatestore_p.h new file mode 100644 index 00000000..560598bf --- /dev/null +++ b/src/datavisualizationqml2/glstatestore_p.h @@ -0,0 +1,99 @@ +/**************************************************************************** +** +** Copyright (C) 2014 Digia Plc +** All rights reserved. +** For any questions to Digia, please use contact form at http://qt.digia.com +** +** This file is part of the QtDataVisualization module. +** +** Licensees holding valid Qt Enterprise licenses may use this file in +** accordance with the Qt Enterprise License Agreement provided with the +** Software or, alternatively, in accordance with the terms contained in +** a written agreement between you and Digia. +** +** If you have questions regarding the use of this file, please use +** contact form at http://qt.digia.com +** +****************************************************************************/ + +// +// W A R N I N G +// ------------- +// +// This file is not part of the QtDataVisualization API.
