Detailed Description

A component that displays the files in a directory as a listbox.

This implements the DirectoryContentsDisplayComponent base class so that it can be used in a FileBrowserComponent.

To attach a listener to it, use its DirectoryContentsDisplayComponent base class and the FileBrowserListener class.
