Detect window manager using KWindowSystem

[Paulo Lieuthier]

Sorry, I've had some problems with my email and the list. Well,
checking the window manager's name is much more reliable, I tested
with many window managers and it worked with all. That's how I'm
doing:

bool LxQtModuleManager::nativeEvent
Filter(const QByteArray & eventType, void * message, long * result)
{
    // a new window manager is started
    if (!mWmStarted && mWaitLoop)
    {
        if (!QString(NETRootInfo(QX11Info::connection(),
NET::SupportingWMCheck).wmName()).isEmpty)
        {
            qDebug() << "Window Manager started";
            mWmStarted = true;
            if (mWaitLoop->isRunning())
                mWaitLoop->exit();
        }
    }

    if (!mTrayStarted && QSystemTrayIcon::isSystemTrayAvailable() && mWaitLoop)
    {
        qDebug() << "System Tray started";
        mTrayStarted = true;
        if (mWaitLoop->isRunning())
            mWaitLoop->exit();

        qApp->removeNativeEventFilter(this);
    }

    return false;
}

The reason for this is that lxqt-session only open the autostart
progams after the window manager is active (and the programs that ask
for a system tray after the system tray is active as well). There
probably is a better way, but that's our solution for now. Thanks for
your help!
