<p>PROBLEM TO BE SOLVED: To display a nondisplay part which is hidden behind another window and not displayed by an information processor, mounted with an overlap type multiwindow system, as to each window displayed on a display device. SOLUTION: When a user inputs a specific indication on a keyboard 11 or with a mouse 12, a CPU 14 finds the addresses of parts where windows overlap with each other from the display positions of all the windows displayed on a display device 18, and read all pieces of display information where bit map data developed into addresses are written out of a main memory 15 as to the respective found addresses, thereby developing the bit map data. Then the OR result of the developed bit map data is written in addresses of a frame memory 16.</p> |
