  13     This class represents the directory chooser dialog.

  15     @beginStyleTable
  16     @style{wxDD_DEFAULT_STYLE}:
  17            Equivalent to a combination of wxDEFAULT_DIALOG_STYLE and
  18            wxRESIZE_BORDER (the last one is not used under wxWinCE).
  19     @style{wxDD_DIR_MUST_EXIST}:
  20            The dialog will allow the user to choose only an existing folder.
  21            When this style is not given, a "Create new directory" button is
  22            added to the dialog (on Windows) or some other way is provided to
  23            the user to type the name of a new folder.
  24     @style{wxDD_CHANGE_DIR}:
  25            Change the current working directory to the directory chosen by the
  26            user.
