<p>PURPOSE:To omit the interruption of user work and the labor of window redisplay by checking whether or not an icon can be accepted in the window, moving the icon to an original position, and reporting an error. CONSTITUTION:An icon moving device 6 detects the moving direction and moving distance of a mouse 9, moves the icon with the current icon position as a reference, stores the position before the movement into a storage 1, and when the position is applied as a parameter, the device 6 moves the icon to the position before the movement. An icon judging device 7 compares the class ID of a class structure obtained by chained-linking the data structure of the icon with the acceptable class ID of the window class structure obtained by chained-linking a pair of the window data structure on the storage 1, and when the window cannot accept the icon, the device 7 instructs the icon moving device 6 to move the icon to the original position.</p> |
