  The Fl_File_Chooser::sort member specifies the sort function that is
  used when loading the contents of a directory and can be customized
  at run-time.

  The Fl_File_Chooser class also exports the Fl_File_Chooser::newButton
  and Fl_File_Chooser::previewButton widgets so that application developers
  can control their appearance and use.  For more complex customization,
  consider copying the FLTK file chooser code and changing it accordingly.

/** @} */

/** \fn Fl_File_Chooser::Fl_File_Chooser(const char *pathname, const char *pattern, int type, const char *title)
  The constructor creates the Fl_File_Chooser dialog shown.
  The pathname argument can be a directory name or a
  complete file name (in which case the corresponding file is highlighted
  in the list and in the filename input field.)
  
  The pattern argument can be a NULL
  string or "*" to list all files, or it can be a
  series of descriptions and filter strings separated by tab
  characters (\\t). The format of filters is either
  "Description text (patterns)" or just "patterns". A file chooser
  that provides filters for HTML and image files might look like:
  
  \code
  "HTML Files (*.html)\tImage Files (*.{bmp,gif,jpg,png})"
  \endcode
  
  The file chooser will automatically add the "All Files (*)"
  pattern to the end of the string you pass if you do not provide
  one. The first filter in the string is the default filter.
  
  See the FLTK documentation on fl_filename_match()
  for the kinds of pattern strings that are supported.
  
  The type argument can be one of the following:
  
  \li \c SINGLE - allows the user to select a single, existing file.
  \li \c MULTI - allows the user to select one or more existing files.
  \li \c CREATE - allows the user to select a single, existing file or
         specify a new filename.
  \li \c DIRECTORY - allows the user to select a single, existing directory.
  
  The title argument is used to set the title bar text for the
  Fl_File_Chooser window.
