problem understanding pygtk

i'm trying to develop a trivial application which random copy files
from a directory to another one.

i made it using pygtk for the graphical interface, however i find
some problem with progressbar and ListStore:

basically i need to make pulse the progressbar while i'm copying files
and write filenames copied on the ListStore on to the window.

However while copying the window is frozen, even if files are copied
one by one and when the copy process finish the window is updated
This behaviour is well shown if i try to copy files to slow devices
such as usb disk.

Looking to example in pygtk i though one way to solve this problem
was using gtk.timeouts or using thread , but none of them seems
to work.

Any hints ? The code is attached here, hoping someone can help me

You need to call gtk.main_iterat ion() to "wake up" the event loop in between
copies. See

you should use:

while gtk.events_pend ing():
gtk.mainiterati on(gtk.FALSE)

in the loop, it requests a refresh of the gui.
So if you use a loop to iterate over a list of files insert that two
lines in the loop, and your gui will be refreshed every iteration.
I quit drinking and smoking once. Very boring 15 minutes.
