    @class wxDirDialog
    @wxheader{dirdlg.h}

    This class represents the directory chooser dialog.

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

    Pops up a directory selector dialog. The arguments have the same meaning as
    those of wxDirDialog::wxDirDialog(). The message is displayed at the top,
    and the default_path, if specified, is set as the initial selection.
    The application must check for an empty return value (if the user pressed
    Cancel). For example:

    @code
    const wxString& dir = wxDirSelector("Choose a folder");
    if ( !dir.empty() )
    {
      ...
    }
    @endcode
