The tutorial chapters can be found in the +Qt documentation, which can be viewed using Qt Assistant or a Web browser. + +The tutorial is also available online at + +http://doc.trolltech.com/4.4/tutorial.html + +All programs corresponding to the chapters in the tutorial should +automatically be built when Qt is compiled, or will be provided as +pre-built executables if you have obtained a binary package of Qt. + +If you have only compiled the Qt libraries, use the following instructions +to build the tutorial. + +On Linux/Unix: + +Typing 'make' in this directory builds all the programs (part1/part1, +part2/part2, part3/part3 and so on). Typing 'make' in each subdirectory +builds just that tutorial program. + +On Windows: + +Create a single Visual Studio project for the tutorial directory in +the usual way. You can do this by typing the following at the command +line: + +qmake -tp vc + +You should now be able to open the project file in Visual Studio and +build all of the tutorial programs at the same time. + +On Mac OS X: + +Create an Xcode project with the .pro file in the tutorial directory. +You can do this by typing the following at the command line: + +qmake -spec macx-xcode + +Then open the generated Xcode project in Xcode and build it. + +Feel free to send comments about the tutorial to qt-bugs@trolltech.com. diff --git a/examples/tutorials/addressbook/addressbook.pro b/examples/tutorials/addressbook/addressbook.pro new file mode 100644 index 0000000..4607c25 --- /dev/null +++ b/examples/tutorials/addressbook/addressbook.pro @@ -0,0 +1,8 @@ +TEMPLATE = subdirs +SUBDIRS = part1 part2 part3 part4 part5 part6 part7 + +# install +target.path = $$[QT_INSTALL_EXAMPLES]/tutorials/addressbook +sources.files = $$SOURCES $$HEADERS $$RESOURCES $$FORMS addressbook.pro README +sources.path = $$[QT_INSTALL_EXAMPLES]/tutorials/addressbook +INSTALLS += target sources diff --git a/examples/tutorials/addressbook/part1/addressbook.cpp b/examples/tutorials/addressbook/part1/addressbook.cpp new file mode 100644 index 0000000..d0107ba --- /dev/null +++ b/examples/tutorials/addressbook/part1/addressbook.cpp @@ -0,0 +1,68 @@ +/**************************************************************************** +** +** Copyright (C) 2009 Nokia Corporation and/or its subsidiary(-ies). +** Contact: Qt Software Information (qt-info@nokia.com) +** +** This file is part of the examples 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.
