Only widgets that can receive keyboard focus themselves can emit "focus-in". But containers have a "set-focus-child" signal so this might be what you need: ===================================================================== import gtk win = gtk.Window(gtk.WINDOW_TOPLEVEL) win.connect('destroy', gtk.main_quit) hbox = gtk.HBox() win.add(hbox) def child_focused(widget, child, i): print('A child in vbox #%u got focus.' % i) for i in range(3): vbox = gtk.VBox() hbox.add(vbox) for j in range(5): entry = gtk.Entry() vbox.add(entry) vbox.connect('set-focus-child', child_focused, i+1) win.show_all() gtk.main() ===================================================================== Yeti
