    @class wxDirDialog

    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.
    @endStyleTable

    Notice that @c wxRESIZE_BORDER has special side effect under recent (i.e.
    later than Win9x) Windows where two different directory selection dialogs
    are available and this style also implicitly selects the new version as the
    old one always has fixed size. As the new version is almost always
    preferable, it is recommended that @c wxRESIZE_BORDER style be always used.
    This is the case if the dialog is created with the default style value but
    if you need to use any additional styles you should still specify @c
    wxDD_DEFAULT_STYLE unless you explicitly need to use the old dialog version
    under Windows. E.g. do
    @code
        wxDirDialog dlg(NULL, "Choose input directory", "",
                        wxDD_DEFAULT_STYLE | wxDD_DIR_MUST_EXIST);
    @endcode
    instead of just using @c wxDD_DIR_MUST_EXIST style alone.

    The application must check for an empty return value (if the user pressed
