As stated earlier, visible objects are nearly useless unless you subclass one of the visible classes and handle certain messages. Although there's a lot of functionality built into VisClass and its subclasses, they must be customized to be of any use. In addition, visible objects must be put into a visible tree and connected to a GenView or other windowed UI object to be displayed.
