[pygtk] Gtk programming technique question...

[GSO]

Quick coding problem if I may.

I am displaying jpegs from CCTV cameras in a HBox, but need some way
to refresh the images in that box.  I need to show the main window,
but then refresh the images in that window.  How would I do this given
after opening the window the programs then waits at the gtk.Main event
loop.

Have tried with the multiprocessing module, but any new threads don't
seem to be able to access the memory of the main window to be able to
refresh the images.

RHEL6, pygtk2 v2.16, Gtk v2.18.9

Thanks in advance,
