123 <h3>FileHistory</h3>
124
125 wxFileHistory encapsulates functionality to record the last few files
126 visited, and to allow the user to quickly load these files using the
127 list appended to a menu, such as the File menu.
128
129 <p>Note that this inclusion is not automatic; as illustrated in this example,
130 you must add files (and remove them) as deemed necessary within the framework
131 of your program.
132
133 <p>Note also the additional cleanup required for this class, namely trapping the
134 enclosing window's Destroy event and deleting the file history control and its
135 associated menu.
