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