#!/usr/bin/env python # -*- coding: utf-8 -*- # 2009-12-27 David Goncalves - Version 1.2 # Total rewrite of NUT-Monitor to optimize GUI interaction. # Added favorites support (saved to user's home) # Added status icon on the notification area # # 2010-02-26 David Goncalves # Added UPS vars display and the possibility to change values # when user double-clicks on a RW var. # # 2010-05-01 David Goncalves # Added support for PyNotify (if available) # # 2010-05-05 David Goncalves # Added support for command line options # -> --start-hidden # -> --favorite # # NUT-Monitor now tries to detect if there is a NUT server # on localhost and if there is 1 UPS, connects to it. # # 2010-10-06 David Goncalves - Version 1.3 # Added localisation support import gtk, gtk.glade, gobject import sys import base64 import os, os.path import platform import time import threading import optparse import ConfigParser import locale import gettext import PyNUT #
