Hi, thanks for the reply.  I think that doesn't work and/or you 
misunderstood.  Demo:

http://assorted.svn.sourceforge.net/viewvc/assorted/sandbox/trunk/src/py/gtk/eventquirks.py?revision=1149&view=markup

from gtk import *
e = Entry()
def handler(*args): print e.get_window().get_geometry()
#e.connect('focus-in-event', handler) 
 

e.connect('configure-event', handler)
h = HBox()
h.pack_start(e)
w = Window()
w.add(h)
w.show_all()
main()

Try resizing/moving the window - nothing happens.

If you uncomment the commented line, then you'll see that the geometry 
doesn't get updated as soon as you resize the window - only on the next 
move/resize will you see the (prior) updated geometry printed.
