ABSTRACT:
The effective display area of a window, in a window display apparatus, is corrected to prevent it from protruding beyond the visible area of the display. A coordinate data input device selects an icon and moves the icon to the display area to display a window image. Depending upon the location to which the icon is moved, correction of the resulting image may be necessary to ensure that the effective display area is shown. Once a window has been displayed, no correction is performed if the window is subsequently moved.
