The Help System application program interface is designed especially for use with OSF/Motif applications. Specifically, Help extends the OSF/Motif widget set by providing two new widget classes (plus convenience functions to manipulate them):
General help dialog, which provides a help window that includes a menu bar and a topic tree, in addition to a help topic display area.
Quick help dialog, which provides a simple help window with a topic display area and a few dialog buttons.
You can use either or both of these types of help windows within your application. Once the application is compiled (with the Help library), the help windows become part of the application.
Chapter 9, Creating and Managing Help Dialog Boxes, describes the general help and quick help dialog boxes.
