<p>PURPOSE: To reduce information volume to be held in an window, to save resouces necessary for the whole computer system and to speed up processing by allowing an window block to execute display and input in each item. CONSTITUTION: Windows A7, B8, C9 displayed on a bit map display respectively correspond to window blocks A10, B11, C12 and all windows are managed by a management block 13. When a position is inputted from a point device, whether an item exists in the inputted coordinate position or not is inspected. When an item exists in the input coordinate position and a processing symbol for the item exists, an window block informs the processing symbol to the block 13. The block 13 executes defined processing in accordance with the informed processing symbol.</p> |
