This article describes a method of maintaining and manipulating a graphical list in the OS/2 Presentation Manager environment. Often, an application lists a group of objects in a graphical format, providing one picture for each item in the list. The Presentation Manager provides list facilities that allow applications to furnish bit image graphics to represent a list item. If the drawings are more complex, the list facility does not store the graphics, although it may notify the application to draw complex graphics in real time on behalf of the list facility. In either case, the list facility must also maintain a linked list of data describing the logical ordering of the discrete graphical objects.
