Abstract
In a data processing system which defines and processes objects and defines a plurality of virtual screens of display data with which views of objects can be associated, the system defines distinct anterior and posterior display layers for display, with the anterior layer having a background such that the content of the posterior display layer can be viewed therethrough and with one of the layers being assignable for the display of a selected virtual screen and the other display layer being dedicated for the display of an additional screen. The system also provides for the transfer of objects between the anterior and posterior display layers such that the dedicated layer can be used for transporting objects between virtual screens.
