6. The display control apparatus as claimed in claim 1 , wherein the determination section determines, for each of the character strings having been judged as having a necessary display width greater than the width of the display area of said display device as a result of comparison by said comparison section, whether or not the character string, as it appeared when it was being judged to have a necessary display width greater than the width of the display area of said display device, contains the particular character string portion.
1. A display control apparatus comprising: a storage section that stores a plurality of data items; a display device that has a display area of a predetermined width for displaying character strings identifying individual ones of the plurality of data items stored in said storage section; a comparison section that compares a necessary display width of each of the character strings and a width of the display area of said display device; a determination section that determines, for each of the character strings having been judged as having a necessary display width greater than the width of the display area of said display device as a result of comparison by said comparison section, whether or not the character string contains a particular character string portion uniquely different between character strings of the plurality of data items; and a display control section that causes said display device to display a list of the character strings identifying the individual data items stored in said storage section, and that, for each of the character strings having been determined by said determination section as containing the particular character string portion, performs control to display the character string in the list in a display style where at least the particular character string portion is left in the list with another part of the character string omitted from the list.
