Review request for Plasma.


Repository: plasma-workspace


Description
-------

    this enables applications (such as the about-distro kcm) to list the
    version of plasma the user is running at runtime in a somewhat reliable
    manner, short of having a library function.

Testing
-------

read version... example code for reading:

    const QStringList &filePaths = QStandardPaths::locateAll(QStandardPaths::GenericDataLocation,
                                                             "xsessions/plasma.desktop");

    if (filePaths.length() < 1) {
        return QString();
    }

    // Despite the fact that there can be multiple desktop files we simply take
    // the first one as users usually don't have xsessions/ in their $HOME
    // data location, so the first match should (usually) be the only one and
    // reflect the plasma session run.
    KDesktopFile desktopFile(filePaths.first());
    return desktopFile.desktopGroup().readEntry("X-KDE-PluginInfo-Version", QString());


Thanks,

Harald Sitter
