Display processing method for windows graphical user interface, involves transferring window content into additional storage zone and matching window size displayed by expansion or compression

摘要

When calling up the alteration mode, the actual window content (9) of the relevant user program (6) is transferred point-by-point into an additional storage zone with a bit- map in case an actual bit-map is not already provided. The window content can be matched to the actual window contour (22) during the alteration mode by stretching and/or compression. When leaving the alteration mode, the content of the display window (8') is again fully generated afresh by the application program only when an update (refresh) requirement is present.
