Abstract

A method and apparatus provide a direct manipulation protocol to allow a user, while dragging a source object to a target object, to pass the source object through one or more intervening processor objects, causing an appropriate action to occur to the source object when it is dropped on the target object. If the source object is passed across a processor object for which no appropriate action occurs, the source object remains unchanged in appearance and content. If the source object undergoes modification, its graphical representation to the user changes, giving the user feedback that the source object has been modified.
