accessed from any application.
Use install_name
and read Apple's
"Creating a Framework"
as well as Qt's "Deploying an Application on Mac OS X" if you customize your path.
LIBS *= -L/path/to/lib -lQGLViewer
Unix syntax if you compiled a dylib instead of a framework.

-Wl,-rpath
syntax so that your executable finds the library.
In case you are prompted with an error while loading shared libraries
message when executing the program, fix that path.
An other option is to copy libQGLViewer.so
(created when you compiled the QGLViewer library) to your app's directory,
or (better) move it to a standard library directory (such as /usr/lib
, as is done when you make install
).
LIBS *= -lXi
in the .pro
file.
Debian users may have to replace -lQGLViewer
by -lQGLViewer-2
in their .pro
.
See also how to customize your .pro or the libQGLViewer on Unix installation page.
.pro
for your application
Qt uses a .pro
file to tune the compilation settings. The one that comes with the examples is pretty involved since it
tries to automatically detect where the library and headers files are located. There is no need to change it: the examples should compile out of the box.
.pro
for your own projects. You need to set these three important variables in order to use libQGLViewer:
INCLUDEPATH
which must indicates where to find the QGLViewer's include files. Since the #include
s use a QGLViewer/qglviewer.h
syntax,
the QGLViewer
suffix should be omitted in this path (if libQGLViewer was installed in the /xxx/yyy/QGLViewer
directory, you will set this variable to INCLUDEPATH *= /xxx/yyy
).LIBS
which tells that your program links with libQGLViewer. Use LIBS *= -L/path/to/lib -lQGLViewer2
, where /path/to/lib
is the path to the libQGLViewer lib (named libQGLViewer2.{so|a|dylib}
or QGLViewer2.lib
depending on your architecture). Use -framework QGLViewer
instead if you compiled a Framework instead of a dylib
on Mac (default).
QT
which lists the required Qt modules: QT *= opengl xml
is a minimum..pro
(change the paths according to your configuration):
TARGET = myViewer CONFIG *= qt opengl release QT *= opengl xml HEADERS = myViewer.h SOURCES = myViewer.cpp main.cpp # Windows INCLUDEPATH *= C:/Users/login/Documents/libQGLViewer-2.9.1 LIBS *= -LC:/Users/login/Documents/libQGLViewer-2.9.1/QGLViewer -lQGLViewer2 # Linux INCLUDEPATH *= /home/login/Documents/libQGLViewer-2.9.1 LIBS *= -L/home/login/libQGLViewer-2.9.1/QGLViewer -lQGLViewer # Mac INCLUDEPATH *= /Users/login/Documents/libQGLViewer-2.9.1 LIBS *= -F/Users/login/Library/Frameworks -framework QGLViewer
.pro
, you can add the QGLViewer's headers path (without the trailing QGLViewer
) to C/C++ / General / Additional Include Directories
and add QGLViewer2.lib
to the Linker / Input / Additional Dependencies using the project properties.
These settings can also be shared by all your projects by setting the Tools / Options / Directories Include and Library values.

draw()
method to define your own scene.
Overload the init()
function to initialize your scene as well as the OpenGL state (such as textures and objects).
Read the principles of the library for details. If not already done, try out the
different examples and feel free to cut and paste code for the functionalities you need.
main
method to translate the texts of your interface.
QApplication application(argc,argv); QString locale = QLocale::system().name(); QTranslator translator; translator.load(QString("qglviewer_") + locale); // translator.load(your application specific translation file(s)); app.installTranslator(&translator);This assumes that
qglviewer_*.qm
is located in your application directory. If it is not the case, copy it or use the overloaded load
method:
translator.load(QString("qglviewer_") + locale, "C:\\Users\\login\\Documents\\Code\\libQGLViewer\\QGLViewer"); // for instanceQGLViewer translation files are available in the QGLViewer's header directory.
