Yes, I do that.

class ImageViewer : public cPlayer {
    ...
}

class SlideshowControl : public cControl {
    ...
}

SlideshowControl::SlideshowControl () :cControl (m_viewer=new ImageViewer()){
    ...
}

I do that too.

cOsdObject * cPluginSlideshowViewer::MainMenuAction () {
    // create and launch the control
    cControl::Launch (new SlideshowControl () );
    return NULL;
}


This is with 1.1.20.
