#!/usr/bin/python

#load in our glade interface

xml.add_from_file('tut02-buttons.glade')
#grab our widget using get_object this is the name of the widget from glade, window1 is the default name
self.window = xml.get_object('window1')
self.text = xml.get_object('entry1')
self.buttons = {}
self.buttons['but1'] = xml.get_object('button1')
self.buttons['but2'] = xml.get_object('button2')
self.buttons['but3'] = xml.get_object('togglebutton1')

self.buttons['but1'].connect('clicked', self.button_events)
self.buttons['but2'].connect('clicked', self.button_events)
self.buttons['but3'].connect('clicked', self.button_events)
