Some applications may benefit from allowing the user to have multiple data files open at any given time. GeoWrite and GeoDraw, for example, allow the user to work with multiple documents at once. Each document appears within its own window; each of these windows is a GenDisplay object within a Display Control object.
The Display Control objects, like the Document Control objects, allow applications to use multiple data files with a minimum of extra coding. The Display Control works closely with the Document Control to ensure that the proper data files are being operated on at all times. The Display Control also creates and maintains the Window menu, just as the Document Control creates and maintains the File menu.
