  12     This control can  be used to place a directory listing (with optional
  13     files) on an arbitrary window.
  14
  15     The control contains a wxTreeCtrl window representing the directory
  16     hierarchy, and optionally, a wxChoice window containing a list of filters.
  17
  18     @beginStyleTable
  19     @style{wxDIRCTRL_DIR_ONLY}
  20            Only show directories, and not files.
  21     @style{wxDIRCTRL_3D_INTERNAL}
  22            Use 3D borders for internal controls.
  23     @style{wxDIRCTRL_SELECT_FIRST}
  24            When setting the default path, select the first file in the
  25            directory.
  26     @style{wxDIRCTRL_EDIT_LABELS}
  27            Allow the folder and file labels to be editable.
