<p>PURPOSE:To scroll plural screens independently of and simultaneously with each other by accepting en bloc the scroll events. CONSTITUTION:An event acceptance processing part 3 is provided to collectively accept the information of scroll events together with a screen processing part 4 which scrolls only its own screen, and the screen information 5 provided in a local area. The part 3 accepts the events in response to the scrolling operations received from the screens and decides that these events should be simultaneously scrolled. Thus the scrolling events are informed to the part 4. Then the part 4 scrolls the screens independently of each other by reference to the information 5 on its own local area.</p> |
