Abstract
A scheme for controlling a screen display capable of allowing the addition of new functions such as the note entry and the pointing according to the input events not requested by the application program, and preserving the meaning attributed to the drawings related to the windows even when the window state change is made. The screen display is controlled by transmitting the inputs entered at the input device as input events to an application program, and supplying the display requests made by the application program according to prescribed types of the input events as well as the display requests according to the input events other than the prescribed types to the output device. Also, when the display of the window data is changed, the display of the drawing data is also changed in accordance with a change made in the display of the window data. Drawing data superposes or overlays separate window data.
