<p>PURPOSE:To dispense with coding of a hidden surface processing of a window in simplified language which can execute coding of a graphical user interface. CONSTITUTION:A simplified language program source 21 for displaying a window 27 on a display device 26 is generated. In this case, a processing for redisplaying the hidden surface 28 of the window is not subjected to coding. A source program is compiled by a simplified language compiler 22, a lode module 23 is generated, and it is executed. In this case, a simple language window access library 24 executes a processing for displaying to the window, and by storing the contents displayed on the window, a hidden surface redisplay request from a window system 25 is received, and a hidden surface processing (redisplay processing) is executed.</p> |
