    Qt Mobility is not only for mobile platforms. It also contains some support (limited afaik) for desktop platforms

      Still I am afraid since this not an option since I have to port my already finished app to Qt Mobility. I would be surprised if it would work the same as on plain Qt, since it is a 52 inch multitouch application using heavy QGraphicsView stuff. But thanks for the effort.

        all you need is link QtM to your app and start use it, there is no needance for rewriting

          Okay, that would be cool. I will look into it. Thanks!

            I'm having problems getting Qt Mobility to work. First I thought it was because I was using Qt SDK 2010.05. So I installed the latest SDK (1.1.2) from http://qt.nokia.com/downloads/. Which claims to contain Qt Mobility version 1.1.3. However after installing I created a simple app from Qt documentation using QMediaPlayer, see http://doc.qt.nokia.com/qtmobility-1.1.3/quickstart.html.

            If I try to compile it complains about the following:

            #include <QMediaPlayer> main.cpp:2:24: error: QMediaPlayer: No such file or directory

            QTM_USE_NAMESPACE main.cpp:6: error: expected constructor, destructor, or type conversion before 'int'

            I must be missing out on something. Should I build Qt Mobility myself. I even can't seem to find the source files for it in the SDK directories :-s

              AFAIK desktop Qt in QtSDK doesn't contain QtMobility. You have to build it manually or use one precompiled (if you use some package-based linux distro it will be easy to install it from repos).

                It does contain it. The create project wizard even supports creating a mobile project. Which still feels weird since I am targeting a 52" inch desktop environment ;-)

                This is the .pro file created (and my changes):

                @

                Add files and directories to ship with the application

                by adapting the examples below.

                file1.source = myfile

                dir1.source = mydir

                DEPLOYMENTFOLDERS = # file1 dir1

                symbian:TARGET.UID3 = 0xE80DF1B4

                Smart Installer package's UID

                This UID is from the protected range

                and therefore the package will fail to install if self-signed

                By default qmake uses the unprotected range value if unprotected UID is defined for the application

                and 0x2002CCCF value if protected UID is given to the application

                #symbian:DEPLOYMENT.installer_header = 0x2002CCCF

                Allow network access on Symbian

                symbian:TARGET.CAPABILITY += NetworkServices

                If your application uses the Qt Mobility libraries, uncomment

                the following lines and add the respective components to the

                MOBILITY variable.

                CONFIG += mobility
                MOBILITY += multimedia

                SOURCES += main.cpp mainwindow.cpp
                HEADERS += mainwindow.h
                FORMS += mainwindow.ui

                Please do not modify the following two lines. Required for deployment.

                include(deployment.pri)

                qtcAddDeployment()

                @

                And here is my main.cpp:

                @
                #include "mainwindow.h"
                #include <QApplication>
                #include <QMediaPlayer>

                int main(int argc, char *argv[])
                {
                QApplication app(argc, argv);

                MainWindow mainWindow;
                mainWindow.setOrientation(MainWindow::ScreenOrientationAuto);
                mainWindow.showExpanded();
                
                return app.exec();
                

                }
                @

                And it does not compile for previous posted reasons!

                  Qt Creator is only part of Qt SDK and another part is Qt library itself. Your errors really looks like QtM is missing, aren't they?

                    Do you have
                    @
                    #include <QtMultimediaKit>
                    @
                    and more importantly, did you select Qt Mobility APIs in the Updater?

                      Yes, QtM appears to be missing. But when I go this url it says QtM is part of the SDK:

                      https://qt.nokia.com/products/qt-addons/mobility

                      That's also claimed on this page, from where I downloaded and installed the SDK:

                      https://qt.nokia.com/downloads

                      Check these screenshots from my system for more details:

                        It can be part of mobile libraries (symbian, maemo), I'm not sure on this btw (I'm using mostly selfbuilded Qt or Qt from my linux repo).

                          Try copying the mobility.prf from QtSDK/Simulator/Qt/gcc/mkspecs/features to QtSDK/Desktop/Qt/gcc/mkspecs/features

                          EDIT: This might not work. Don't be disappointed if it doesn't.

                              I did. Same errors after reloading and rebuilding the project.

                                Finally I succeeded achieving this in Phonon on Windows 7. I just adjusted the volume level to create the fade out.
