From 401f078386a8b5a87a58e237de7be9a2f9a045ba Mon Sep 17 00:00:00 2001 From: Lars Knoll Date: Wed, 4 May 2011 12:50:14 +0200 Subject: split kernel/ up according to the future library split Create a guikernel/ directory that contains the files that'll go into libQtGui. What remains in kernel/ will go into QtWidgets. In addition to that image/, painting/ and text will end up int QtGui. --- src/gui/guikernel/qplatformintegration_qpa.cpp | 225 +++++++++++++++++++++++++ 1 file changed, 225 insertions(+) create mode 100644 src/gui/guikernel/qplatformintegration_qpa.cpp (limited to 'src/gui/guikernel/qplatformintegration_qpa.cpp') diff --git a/src/gui/guikernel/qplatformintegration_qpa.cpp b/src/gui/guikernel/qplatformintegration_qpa.cpp new file mode 100644 index 0000000000..8ff12ebf9c --- /dev/null +++ b/src/gui/guikernel/qplatformintegration_qpa.cpp @@ -0,0 +1,225 @@ +/**************************************************************************** +** +** Copyright (C) 2011 Nokia Corporation and/or its subsidiary(-ies). +** All rights reserved. +** Contact: Nokia Corporation (qt-info@nokia.com) +** +** This file is part of the QtGui module of the Qt Toolkit. +** +** $QT_BEGIN_LICENSE:LGPL$ +** No Commercial Usage +** This file contains pre-release code and may not be distributed. +** You may use this file in accordance with the terms and conditions +** contained in the Technology Preview License Agreement accompanying +** this package. +** +** GNU Lesser General Public License Usage +** Alternatively, this file may be used under the terms of the GNU Lesser +** General Public License version 2.1 as published by the Free Software +** Foundation and appearing in the file LICENSE.LGPL included in the +** packaging of this file.

It has factory functions for creating platform specific pixmaps and + windows. The class also controls the font subsystem. + + QPlatformIntegration is a singelton class which gets instansiated in the QApplication + constructor. The QPlatformIntegration instance do not have ownership of objects it creates in + functions where the name starts with create. However, functions which don't have a name + starting with create acts as assessors to member variables. + + It is not trivial to create or build a platform plugin outside of the Qt source tree. Therefor + the recommended approach for making new platform plugin is to copy an existing plugin inside + the QTSRCTREE/src/plugins/platform and develop the plugin inside the source tree. + + The minimal platformintegration is the smallest platform integration it is possible to make, + which makes it an ideal starting point for new plugins. For a slightly more advanced plugin, + consider reviewing the directfb plugin, or the testlite plugin. +*/ + +/*! + \fn QPixmapData *createPixmapData(QPixmapData::PixelType type) const + + Factory function for QPixmapData.
