From 3d3bf7cf3c94225be59966d1c6b79559cc251f95 Mon Sep 17 00:00:00 2001 From: Thiago Macieira Date: Wed, 5 Aug 2009 12:11:42 +0200 Subject: Autotest: add QSharedPointer and QWeakPointer tests for QWidget too I don't want to link the tst_qsharedpointer test to QtGui, so I created a new test. This is testing only the basic manipulations. In special, it's not testing invalid constructs. --- tests/auto/auto.pro | 3 +- .../qsharedpointer_and_qwidget.pro | 3 + .../tst_qsharedpointer_and_qwidget.cpp | 150 +++++++++++++++++++++ 3 files changed, 155 insertions(+), 1 deletion(-) create mode 100644 tests/auto/qsharedpointer_and_qwidget/qsharedpointer_and_qwidget.pro create mode 100644 tests/auto/qsharedpointer_and_qwidget/tst_qsharedpointer_and_qwidget.cpp diff --git a/tests/auto/auto.pro b/tests/auto/auto.pro index 2550dcd..c923dee 100644 --- a/tests/auto/auto.pro +++ b/tests/auto/auto.pro @@ -270,7 +270,8 @@ SUBDIRS += _networkselftest \ qscriptenginedebugger \ qscrollarea \ qsemaphore \ - qsharedpointer \ + qsharedpointer \ + qsharedpointer_and_qwidget \ qsequentialanimationgroup \ qset \ qsettings \ diff --git a/tests/auto/qsharedpointer_and_qwidget/qsharedpointer_and_qwidget.pro b/tests/auto/qsharedpointer_and_qwidget/qsharedpointer_and_qwidget.pro new file mode 100644 index 0000000..db647a5 --- /dev/null +++ b/tests/auto/qsharedpointer_and_qwidget/qsharedpointer_and_qwidget.pro @@ -0,0 +1,3 @@ +load(qttest_p4) +SOURCES += tst_qsharedpointer_and_qwidget.cpp +DEFINES += SRCDIR=\\\"$$PWD/\\\" diff --git a/tests/auto/qsharedpointer_and_qwidget/tst_qsharedpointer_and_qwidget.cpp b/tests/auto/qsharedpointer_and_qwidget/tst_qsharedpointer_and_qwidget.cpp new file mode 100644 index 0000000..66727c2 --- /dev/null +++ b/tests/auto/qsharedpointer_and_qwidget/tst_qsharedpointer_and_qwidget.cpp @@ -0,0 +1,150 @@ +/**************************************************************************** +** +** 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.
