8Right-click on the panel above the line to get a menu. This menu will
9be managed by a FileHistory object and so the files you select will
10automatically be added to the end of the menu and will be selectable
11the next time the menu is viewed. The filename selected, either via the
12Open menu item, or from the history, will be displayed in the log

125wxFileHistory encapsulates functionality to record the last few files
126visited, and to allow the user to quickly load these files using the
127list appended to a menu, such as the File menu.

129<p>Note that this inclusion is not automatic; as illustrated in this example,
130you must add files (and remove them) as deemed necessary within the framework
131of your program.
132
133<p>Note also the additional cleanup required for this class, namely trapping the
134enclosing window's Destroy event and deleting the file history control and its
135associated menu.
