In order to display all information to be displayed on a computer screen in a manner which is easy to understand in hierarchical window displaying, an entire screen is taken as a root window, and display objects of windows and icons corresponding to child windows of the root window are arranged on the root window. Lower order windows and icons are also present within the child windows. The sizes of the windows are user-programmable, and each window has its own independent scale. The scales are decided in such a manner that a proportion occupied by the total surface area of the display objects within a window is fixed or does not exceed a fixed value with respect to the surface area of the window.
