python GTK dialog script

Hi all, I'm in the process of writing a dialog for GTK using python, I already have all the functionality I need but I have a small problem. When I press a button on the dialog window to call an external program as Firefox the dialog becomes unresponsive until I close Firefox. I'd like to be able to call Firefox and still be able to call Exaile without having to close Firefox. Any suggestions?

import pygtk
pygtk.require("2.0")
import sys, gtk, gtk.glade, os, os.path, gobject

f_name =".utopia.rc" #Preferences file

filename = os.path.expanduser( os.path.join( "~/.config", f_name ) )  #If preferences file exists
if os.path.exists(filename) == 1:
    quit ()

#-----------------------------------------------

def do_exit (action): #quit program
    gtk.main_quit ()

def do_browser (action): #run Firefox
    os.system('firefox www.utopia.org &')

def do_appearances (action): #run gnome-appearance-properties
    os.system('gnome-appearance-properties ')

def do_music (action): #run exaile
    os.system('exaile')

def do_check (action): #if user wants to run this next time
    if checkbutton.get_active() == 1:
        os.remove(filename)
    else:
        FILE = open(filename,"w")
        FILE.writelines("WELCOME_SCREEN=1")
        FILE.close()

#-----------------------------------------------

xml = gtk.glade.XML ('/usr/bin/welcome.glade', None, None)

#-----------------------------------------------

window = xml.get_widget ('window')    
button_close = xml.get_widget ('button_close')
checkbutton = xml.get_widget ('checkbutton')
button_internet = xml.get_widget ('button_internet')
button_music = xml.get_widget ('button_music')
button_appearances = xml.get_widget ('button_appearances')

#-----------------------------------------------

button_close.connect ("clicked", do_exit)
checkbutton.connect ("toggled", do_check)
button_internet.connect ("clicked", do_browser)
button_appearances.connect ("clicked", do_appearances)
button_music.connect ("clicked", do_music)

#-----------------------------------------------

window.connect ("destroy", do_exit)
window.show_all ()
gtk.main ()

Tank you.

Re: python GTK dialog script

Strange, but adding '&' in the end works for me:

>>> os.system('emacs')

- interpreter is stuck

>>> os.system('emacs &')

- returns immediately

LOOLL, I've reached the same conclusion as it's treated like a bash command. But thank you for your help.

Re: python GTK dialog script

the new recommended way of running external processes is to use module: subprocess

Re: python GTK dialog script

i use something like this:

import os

os.spawnvp(os.P_NOWAIT,"programname",["","arg1","arg2",...]) # argn are the command line arguments to program.
Here, P_NOWAIT acts like the & in in os.system().
