The problem is that I cannot import gtk.glade (it's a GTK2 import). My first try was this
try:
import gtk
import gtk.glade
except:
sys.exit(1)
import gettext
APP="pytemp"
DIR="po"
gettext.textdomain(APP)
gettext.bindtextdomain(APP, DIR)
gtk.glade.textdomain(APP)
gtk.glade.bindtextdomain(APP, DIR)
But this last 2 lines doesn't work with GTK3, so I don't know how I can change my code... I want to use gettext for translate in different languages but i can't access to Glade strings.
