As far as I know there is no easy way to extract a qvw template and use it in another qvw... There is a wizard that is supposed to help you with that but I've never had success using it. What you can do is... download, open and replace the script in the demo qvw and then start creating your objects in that file. That way you can use the backgrounds and all those nice effects.
If you need to copy an object properties, open another instance of QV and open the demo in it. In the demo, select the object whose properties you want to copy and select the copy format icon (paintbrush ), then clic on the object in which you want to apply those properties.
