I tried to do two things to see if was possible to do something similar, first 
I added all the event mask to the ComboEntry and see which kind of event it 
emit:

import pygtk
pygtk.require('2.0')
import gtk

class FirstWin(gtk.Window): 
    def __init__(self): 
        gtk.Window.__init__(self, gtk.WINDOW_TOPLEVEL)
        self.connect("destroy", lambda w: gtk.main_quit())
        combo = gtk.ComboBoxEntry()
        combo.add_events(gtk.gdk.ALL_EVENTS_MASK)
        combo.connect("event", self.doPrint)
        self.add(combo)
        self.show_all()
        
    def doPrint(self, widget, event, data=None):
        print event.type

    def main(self): 
        gtk.main()

if __name__ == "__main__": 
    first = FirstWin()
    first.main()


But seems that only a few events are emitted, the one that is close to what 
you want is the expose event, button-press-event no way.
The only problem is that this signal is emitted more than what you would like 
to do, so you will have more refresh of your list than the desired.

import pygtk
pygtk.require('2.0')
import gtk

class FirstWin(gtk.Window): 
    def __init__(self): 
        gtk.Window.__init__(self, gtk.WINDOW_TOPLEVEL)
        self.connect("destroy", lambda w: gtk.main_quit())
        combo = gtk.ComboBoxEntry()
        combo.connect("expose-event", self.doPrint)
        self.add(combo)
        self.show_all()
        
    def doPrint(self, widget, event, data=None):
        print "refresh"

    def main(self): 
        gtk.main()

if __name__ == "__main__": 
    first = FirstWin()
    first.main()

The expose event is emitted both when you click the button but also when the 
pointer goes over the button itself.

That's all I could find :)
