I've tried to search, but nothing seems to work. For example:
I am currently writing simple communication app in Python2.7 with PyGTK. I have background process, which is listening socket in while loop like that. I want to display message, when I receive it form server. But when I start gtk.main(), it obviously starts to loop again, so my listening loop doesn't working. I need to display new window for each message or close old window and display new window with all unread messages. Can I somehow display window (or more than one window) and don't block my listening loop?
IOChannel solution
while True: #listening loop
print 'Start'
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sock.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEPORT, 1)
sock.bind((socket.gethostname(), 80))
sock.listen(2)
conn, address = sock.accept()
conn.sendall('200 OK')
fd = conn.fileno() #Make file descriptor from socket
gio_channel = glib.IOChannel(fd) #Pass it to IOChannel
if(new_message):
#display message with gtk.main()
else
#Do something else like update file
subprocess.Popen solution
while True: #listening loop
print 'Start'
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sock.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEPORT, 1)
sock.bind((socket.gethostname(), 80))
sock.listen(2)
conn, address = sock.accept()
conn.sendall('200 OK')
all_json = conn.recv(2048)
if(new_message):
# This script run pygtk app in the background
subprocess.Popen(['python', 'communication_app.py'])
else
#Do something else like update file
