## Description

TFileListBox is a TCustomFileListBox descendant which implements a file selection list box control. It is used to select a file or directory on the local file system. TFileListBox sets the visibility for properties introduced in an ancestor class, and does not contains any new properties, methods, or events.

Use the Drive and Directory properties to specify the location on the local file system displayed in the list box. Please note that Drive is not used on UNIX-like file systems.

Use FileType to specify the files and/or directories which can be displayed in the control.

Use Mask to specify a file mask (with optional wildcards) used to select the files displayed in the control. Please note that wild cards may be implemented differently for some file systems. For example: '*' is the "all files" mask on UNIX-like file systems instead of '*.*'.

Use the Sorted property to control the order of files and directories displayed in the control.

Use the FileName property to get the current file selection in the control.

Assign an object procedure to the OnChange event handler to perform actions needed when a new item has been selected in the control.
