  29     This control can  be used to place a directory listing (with optional
  30     files) on an arbitrary window.
  31
  32     The control contains a wxTreeCtrl window representing the directory
  33     hierarchy, and optionally, a wxChoice window containing a list of filters.

  35     @beginStyleTable
  36     @style{wxDIRCTRL_DIR_ONLY}
  37            Only show directories, and not files.
  38     @style{wxDIRCTRL_3D_INTERNAL}
  39            Use 3D borders for internal controls.
  40     @style{wxDIRCTRL_SELECT_FIRST}
  41            When setting the default path, select the first file in the
  42            directory.
  43     @style{wxDIRCTRL_SHOW_FILTERS}
  44            Show the drop-down filter list.
  45     @style{wxDIRCTRL_EDIT_LABELS}
  46            Allow the folder and file labels to be editable.
  47     @style{wxDIRCTRL_MULTIPLE}
  48            Allows multiple files and folders to be selected.
