From 13254da6c3192937812983f44ce95fe8e1bc602c Mon Sep 17 00:00:00 2001 From: Volker Hilsheimer Date: Fri, 17 Jul 2009 15:40:49 +0200 Subject: Implement QDesktopWidget::screenCountChanged signal on desktop platforms, and add manual testcase. Provide replacement "screenCount" for numScreens and document numScreens as obsolete to be more consistent with other APIs. --- tests/manual/qdesktopwidget/main.cpp | 188 +++++++++++++++++++++++++ tests/manual/qdesktopwidget/qdesktopwidget.pro | 2 + 2 files changed, 190 insertions(+) create mode 100644 tests/manual/qdesktopwidget/main.cpp create mode 100644 tests/manual/qdesktopwidget/qdesktopwidget.pro (limited to 'tests/manual/qdesktopwidget') diff --git a/tests/manual/qdesktopwidget/main.cpp b/tests/manual/qdesktopwidget/main.cpp new file mode 100644 index 0000000000..1afc82eeff --- /dev/null +++ b/tests/manual/qdesktopwidget/main.cpp @@ -0,0 +1,188 @@ +/**************************************************************************** +** +** Copyright (C) 2009 Nokia Corporation and/or its subsidiary(-ies). +** Contact: Nokia Corporation (qt-info@nokia.com) +** +** This file is part of the test suite 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 either Technology Preview License Agreement or the +** Beta Release License Agreement. +** +** 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.
