/**
* A File List widget provides an icon rich view of the file system.
* It automatically updates itself periodically by re-scanning the file system
* for any changes.  As it scans the displayed directory, it automatically
* determines the icons to be displayed by consulting the file associations registry
* settings.  A number of messages can be sent to the File List to control the
* filter pattern, sort category, sorting order, case sensitivity, and hidden file
* display mode.
* The File list widget supports drags and drops of files.
