Method and apparatus for single scroll bars in graphical windows user interface

摘要

A scroll transfer control button is provided so that a single set of scroll controls can be used to alternately control scrolling in a plurality of separate windows which may be concurrently presented on a display device. Each time a scroll transfer control button is activated, active scroll control switches so that scroll control can be transferred from a work object contained in a first displayed window to another displayed window. Active scroll control can be returned to the first displayed window by toggling the scroll control button until the active scroll control returns. The single set of scroll controls is preferably provided at the edge of the edge of the available area for displaying windows containing work objects. The single set of scroll controls can be trivially thin in appearance or may be transparent due to their consistent presentation at an extreme edge of a display area.
