From 288d3884969624037bd201ef78540c06643807e8 Mon Sep 17 00:00:00 2001 From: Lars Knoll Date: Thu, 5 May 2011 14:02:45 +0200 Subject: special directory for stuff we want to move from widgets to gui Create a special to_be_moved directory, that will contain files that are to be moved from QtWidgets to QtGui. This will allow us to do a first split of the libraries rather fast and we can then start pulling in these classes one by one. --- src/gui/text/qlinecontrol_p.h | 456 ------------------------------------------ 1 file changed, 456 deletions(-) delete mode 100644 src/gui/text/qlinecontrol_p.h (limited to 'src/gui/text/qlinecontrol_p.h') diff --git a/src/gui/text/qlinecontrol_p.h b/src/gui/text/qlinecontrol_p.h deleted file mode 100644 index 0042f17261..0000000000 --- a/src/gui/text/qlinecontrol_p.h +++ /dev/null @@ -1,456 +0,0 @@ -/**************************************************************************** -** -** 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.
