* Description:  Interface for controlpanel plugins, with this interface client application can launch a view from outside of controlpanel application.

    \brief The class CpLauncherInterface defines an interface for plugins, if one controlpanel plugin implements

    this interface, client application can launch a setting view from outside of controlpanel application by two ways.

    (1) launch setting view in client process, using CpPluginLauncher.

    \code

    CpBaseSettingView *settingView = CpPluginLauncher::launchSettingView("cpmyplugin.dll",QVariant());

    \endcode

    (2) launch setting view in embedded mode, using QtHighway client API.

    \code

    if (mRequest) {

        delete mRequest;

        mRequest = 0;

    }

    mRequest = mAppMgr.create("com.nokia.symbian.ICpPluginLauncher", "launchSettingView(QString,QVariant)", true);

    if (!mRequest)

    {

        return;

    }

    else

    {

        connect(mRequest, SIGNAL(requestOk(QVariant)), SLOT(handleReturnValue(QVariant)));

        connect(mRequest, SIGNAL(requestError(int,QString)), SLOT(handleError(int,QString)));

    }

    // Set arguments for request 

    QList<QVariant> args;

    args << QVariant("cpmyplugin.dll");

    args << QVariant();

    mRequest->setArguments(args);

    mRequest->setSynchronous(false);    

    // Make the request

    if (!mRequest->send())

    {

        //report error     

    }

    \endcode
