The Address Book Tutorial shows how to put together a simple yet
|
||||
fully-functioning GUI application. 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://qt-project.org/doc/qt-5.0/qtwidgets/tutorials-addressbook.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.
