Use a callback to handle the result and call it from your thread with
gtk.idle_add().

Other idea is waiting until threading.activeCount drops below 2, i.o.w.
you get only one active thread and this is a main thread (this may be of
some use if you spawn more than one worker thread).

See: http://docs.python.org/lib/module-threading.html

import threading
import time

def threadfunction():
# thread: do nothing for ca. 10 seconds
stoptime = time.time() + 10.0
while time.time() < stoptime:
print "thread: running"
time.sleep(1)
print "thread: ending"


t = threading.Thread(target=threadfunction)
t.start()

while t.isAlive():
print "waiting for thread"
time.sleep(1.2)

[pygtk] Wait until a thread is ended

2006-09-28 Thread Adolfo González Blázquez 
Hello,

I would like to know if someone can point me a solution to make a
function run as a separate thread, and wait until it is ended, without
blocking the gui.

In my application, i'm getting a long file listing using glob(), and i
want this function to run as a thread, so the user can stop it using a
button in the gui (right now, the gui freezes till glob is ended), and
then run another function to fill the treeview (this now works without
blocking the gui, using generators). .

Any idea will be really appreaciated.

Thanks in advance!
