Thanks a lot for the updated version! That helped me a lot and I got it
working now. I basically just replaced the insert function with:

def insert(widget, text, pos):
	weight = float(widget.get_text())
	weight += 1
	widget.handler_block(insert_sig)
	widget.set_text(str(weight)
    	widget.handler_unblock(insert_sig)

The only minor problem remaining was, that if the text in the entry is
selected, the selection gets deleted/replaced on any key press. My first
workaound is to prevent the default test selection when focusing on the
entry (with TAB, for examplse) with:

entry.connect('focus-in-event', on_focus)

def on_focus(entry, event):
        gobject.idle_add(entry.set_position, 0)

That seems to me like a quick hack, are there any better solutions?

Thanks again,
Eike
