gui().start()
gtk.main()

it is not working this way either

EDIT:
from bluetooth import *

class gui(threading.Thread):
__def __init__(self):
____.......
____self.entrybox=self.wTree.get_widget('entry2')
____self.sock=BluetoothSocket(RFCOMM)
____self.sock.connect((host,port))
____print 'connected'
____threading.Thread.__init__(self)
__def run(self):
____while 1:
______data=self.sock.recv(1024)
______self.entrybox.set_text(data)


gui().start()
gtk.main()

what i want is to set this device to send and get data whenever it wants.
i got a button in gui that starts send function and it work OK
but problem is whole about this reading function :/
