This work for me:
#!/usr/bin/env python
# -*- coding: utf-8 -*-
import gtk
win = gtk.Window()
image_add = gtk.Image()
image_rem = gtk.Image()
b = gtk.Button()
image_add.set_from_stock(gtk.STOCK_ADD, gtk.ICON_SIZE_BUTTON)
image_rem.set_from_stock(gtk.STOCK_REMOVE, gtk.ICON_SIZE_BUTTON)
def on_clicked(button):
state = button.get_data('state')
if state == '+':
button.set_image(image_rem)
button.set_data('state', '-')
elif state == '-':
button.set_image(image_add)
button.set_data('state', '+')
else:
raise ValueError("unknown state :(")
# setup initial state
b.set_image(image_add)
b.set_data('state', '+')
# connect signals
b.connect('clicked', on_clicked)
win.connect('delete-event', gtk.main_quit)
win.add(b)
win.show_all()
gtk.main()
